Zakki Sieve Pre Sieve Mechanical Filter?
prefilter, mechanical filter, zakki sieve filter questions
i programme on installing a zakki sieve in my filter setup side by side jump, as right now i simply have a foliage basket before the pump(which gets cleaned out daily) but then i have a bio and uv subsequently that. but question is with the zakki does a guy warrant annihilation more than merely a leaf basket? i have saw those cyclones after the pump which trap even more than debris. also with the zakki, does one ever have to clean out a leaf trap? I hateful the screen size on the zakki is a lot smaller than the leaf handbasket grid. is the cyclone necessary? i am not interested in an rdf as i need to have a pressurized suction and belch. i have been reading all that i can, merely but want to directly ask the experts.
Exist a pump primer pot...leaf baseket, a sieve, a RDF, a stack of matting or rows of brushes......they are not a pre-filter. They are all filters.....mechanical ones. They are their to capture insoluble organic stuff like algae, feces, uneatten food, leaves....etc.My mechanical stage for the skimmer excursion is the skimmer basket then a bead filter. My other mechanical phase is a pair of UltrasieveIII units that feed a pump and and so a shower. At that place is aught need after a sieve (or RDF) for a foliage basket on a pump. But, if you have elevated the pump significantly after a sieve or RDF, there could be a need for a the primer pot function and even a check valve.
I flush my Zakki sieve every 24-hour interval and the foliage basket every few days. The handbasket is never horribly bad. I bought the multi-whirlwind at the same time I got the sieve from Zac. Over the class of the season information technology probably didn't capture more than a cup of very fine droppings. This yr I removed it from my system and actually tin can't tell a departure in the clarity of the h2o. I don't retrieve I had the amount of period to make it work efficiently. If information technology wasn't for the Zakki sieve I would probably be cleaning my Nexus twice a day due to the loftier amount of algae it catches. I've had Zac's sieve running for 4 or five years now. I'1000 hoping to put some other i on my skimmer circuit side by side season.
I think in my humble opinion y'all demand a leaf basket after the sieve if yous bypass the sieve when flushing to clean it. I have had pea gravel in the priming pot basket several times. Only then again if y'all do t take anything in y'all pond that may get sucked in to your pump that may harm it there's no worries.
Exactly. Yous should keep the pump leaf basket in place for *when* this happens. Otherwise your pump will be torn up trying to tear up what the sieve normally catches.

I concord with Beak, Kevin and Dave.
The leaf basket is needed for when you lot aftermath the sieve (assuming you hook it up that way) equally well as for if/when the sieve screen were to get too full and pop loose (past design).
I clean my Zakki sieve every morning time (although not actually needed) only because information technology takes me less than a minute. I clean my leaf handbasket whenever I backwash my dewdrop filter and do a water change. Again, not needed just it'south just part of my routine.
I accept the Zakki, pump basket, and cyclone , then I tin can give y'all offset paw info. I flush the Zakki every ii-3 days ; same with the whirlwind ( Physician l ) . Since my ponds are heavily planted, I get more waste product and debris than most . My whirlwind captures a lot of fine sediment; when I affluent, the waste h2o is black ! If it was not there, all the sediment would end upwards back in the pond. I do recommend it . Flushing the cyclone takes no more than 20 seconds.
I don't make clean the pump handbasket very oft; I gauge when to practise it past looking at my waterfall menses; when it looks similar the menses is reduced, I know from feel that the pump strainer handbasket is starting to get clogged. Also, if the Zakki overflows considering you forgot to clean the screen, the Zakki waste material will clog the pump basket in short society, only that won't happen if y'all monitor the Zakki every couple days.
i am past no means getting rid of the leaf basket, just noticed how much smaller the zakki screen is vs foliage basket. i think i volition hold off on the whirlwind for now, but design it so i permit room for it at a afterward appointment if demand be. what happens to the zakki if you lot pull besides much water through it? my pump is rated higher than the capacity by 1100gph, but i oasis't calculated head loss and know i take some. i believe i could put a brawl valve on the discharge side of the pump to restrict it a fleck if need be, simply would prefer non to.
As Kevin stated, if yous pull too much water through the Zakki sieve information technology will catamenia over the spillway in the sieve. That ways that water will not run through the sieve and will get to your pump unfiltered. I use ball valves earlier the sieve and after the dewdrop filter to adapt the flow to pull every bit much through the sieve equally it can handle without flowing over the spillway.
i am by no ways getting rid of the leaf basket, merely noticed how much smaller the zakki screen is vs leaf handbasket. i think i will hold off on the cyclone for now, only design it and so i allow room for it at a afterwards date if need be. what happens to the zakki if you lot pull too much h2o through it? my pump is rated higher than the chapters by 1100gph, but i haven't calculated head loss and know i have some. i believe i could put a ball valve on the discharge side of the pump to restrict information technology a bit if demand be, only would prefer not to.
I run the valve betwixt my BD and sieve fully open and only open the valve from the skimmer approx. one-half way. I take a pump in the skimmer the pulls water and sends it to our plant pond so the feed from the skimmer to the sieve is just for some additional draw through the skimmer but mainly acts as a "safety" feature to keep the pond from draining completely should something happen betwixt the pump and the swimming. If this were to happen the skimmer feed to the sieve would draw air and loose prime number to the pump. I would rather burn upward a pump than than completely bleed the pond.

what is a prefilter and then? seems Zac calls his sieve filter a prefilter. kinda thought mechanical and prefilter went hand on manus. Maybe not
Zac's use is fine if you e'er think that a "filter" is really a device/chamber for nitrification or denitrification. But in reality those ii processes are not filtering....they are converting from one inorganic chemical compound to another (ammonia -> nitrite -> nitrate). Ammonia and nitrite are not removed in a dump port....they are converted to nitrates. The mechanical stage more closely follows the function of a filter as it should capture and remove something. Hence we actually backwash or clear a mechanical phase......and have no need to do that to a nitrification or denitrification sleeping room if the previous mechanical stage did a good job.
does anybody have whatsoever dislikes most the zakki? or tips on what not to do, like install wise what worked better or if you lot had to redo anything subsequently initial install?kevin32, is that a normal amount of debris to clean out? does that amount impact catamenia at all?
We've installed several of these sieves and nosotros DO Not contain all the additional plumbing/valving to arrive supposedly easier to clean. I hateful, if yous can save all that flow loss by eliminating all the valves,elbows and boosted piping, you can but plough off the pump, open the lid and wash downward the screen through the waste product port. Shouldn't take more than about five-10 minutes. Of course, I can't imagine assuasive the sieve to get long enough betwixt cleanings to await similar Kevin's picture, simply then, the pic belies less than ideal overall filtration for that much algae glarf to build up in 2-iii days!
That's almost three days of stuff collecting. I similar to make clean information technology everyday just often get lazy and stretch 2-3 days.
I would say the only downside is all the head pressure you seem to loose and it beingness a pressurized filter seems to loose menses from this too.
I think I may have my 4 way turned upside downwardly so I would have changed that. and if you lot just manually make clean it out then you tin eliminate some of the pipage needed to flush and bypass the sieve.

then when you dont install all the "featherbed" stuff, what does the plumbing wait like? exercise yous just rinse the screen/inside of the zakki with a hose then?
The bypass $.25 on the Zakki sieve is really to allow the pump to run while cleaning the sieve. Equally needed you can flush the sieve with pump water (using that 3way after the pump), or grab a hose and remove the top and flush manually. On a weekly footing I take to remove the screen so that I can inspect and clean both sides of the screen.
so when you dont install all the "bypass" stuff, what does the plumbing wait like? do yous merely rinse the screen/inside of the zakki with a hose and then?
So if yous accept a hose by your equipment, sure, skip the bypass and meliorate flow. If not, then I would include those in a build.
It's is a pretty unproblematic concept, just well made, so it's hard to mutter well-nigh it. I have a three" inlet, 2" out and ii" waste.
does everyone take any dislikes near the zakki? or tips on what non to do, like install wise what worked better or if you had to redo annihilation after initial install?
If I had to do it again I would get a 3" waste. I get a lot of pine needles and they "span" across a 2" waste hands. A 3" would mean less popping the elevation to remove.
I ended up installing the bypass piping and I'm glad I did. It literally merely takes me maybe 30 seconds to flush out the sieve using the bypass valves. Then every morning before I go out for piece of work I rinse off my skimmer screen, affluent the sieve and feed the koi. This whole procedure only takes me merely a few minutes. I only remove the chapeau and hose off the screen while the bead filter is backwashing (before I do a h2o change). I like the idea of not having to employ the clamp latches whatsoever more than I have to. I figure information technology saves habiliment and tear that way (how much, if any, I actually don't know).
so when you dont install all the "bypass" stuff, what does the plumbing look similar? do you just rinse the screen/within of the zakki with a hose and then?
I do agree with Dave, at that place have been a couple of times that I wish the waste product pipage was 3" instead of 2" like in the spring when I had an algae flower. If yous get too much build upwardly in the sieve so you tin can clog the waste material piping and you'll take to remove the lid and free the clog by paw.
I've had my Zakki sieve running for 1.5 yrs now and I'm in dearest with it. I retrieve it depends on your swimming and the amount of debrie weather you do the featherbed or non. Personally I am so glad I did the featherbed, it'south one of my favorite features of the sieve. Summer, autumn and winter I dont collect much in the sieve just I even so flush it every few days because its so fast and like shooting fish in a barrel west/ the bypass. In the spring however for about 6 weeks while everything is coming out of its winter slumber I flush information technology every 24-hour interval because of algae, thats when I couldnt imagine not having the featherbed.I'm with the others as far as the prime pot/foliage basket before your pump, yes... go along it w/ or w/o the bypass, better to exist safe than sorry.
I have a filter room deck behind my pond with all my mechanical and bio filtration. Because I need to feed (2) 55 gal barrels afterwards the sieve that are raised four' higher up pump I used a ESS6400 (medium caput pump) and it is perfect to max out the sieve to its total potential of h2o flow. I did have Zac make my intake iii" for future utilize but as of now it'due south still working with just my 2" retro BD line.
I posted a few pics for you on how I have mine set and how the zakki sieve works with the featherbed line in place. At that place is also one of what mine collects for the few weeks of spring kickoff up (this is the reason that I Dearest having the bypass).
I was very intimidated when I first got my sieve and had no idea how I was going to figure it out and plumb it with the bypass and so it worked. I watched Zacs videos a hundred times and was clueless, then of a sudden information technology merely came to me in one of those "OMG so thats who information technology works" moments. Once I knew how it worked the plumbing was the easy part.
If you decided not to do the bypass in last pic (clean fashion), the 2 lines with 10's on them would not exist needed. You would also not need the (2) three style valves and they could be replace with regular ball valves. Personally, for the two extra pieces of pipe (and the 3 ways come up with the sieve) I wouldnt skip the bypass unless y'all take to much caput for your pump already and want/need the extra h2o catamenia.
Sorry for the book
Hope this helps

I had a Zakki Sieve for my mechanical filtration, the smaller vortex after my pump as suggested and especially designed a Japanese Lantern way bio shower with a waterfall weir. I think this is a pretty good set up Zak designed for me but it wasn't enough bio for my fish load. That is another conversation. :-) We abound equally we learn. :-)With that existence said, the sieve is mechanical equally it provides no bio function at all. It'southward role is to take the debris and particles out of the water.
In order for "me" to accept expert mechanical I had to affluent my sieve twice a day (a bit anal) and I flushed my vortex every other twenty-four hours. That took a few minutes a week so information technology wasn't much piece of work at all. Talking to Zak about the vortex from fourth dimension to time about the "fine" particles, I came to realize it provided some benefit but not plenty for me to suggest someone buying information technology.
The level of debris in your sieve comes with many factors. Feeding, fish waste, trees, plants in your h2o, etc. The cleaner your sieve, the cleaner your water. You must know the sieve can't get all of the really modest fines as they pass over the screen. This is why it is of import to make clean your sieve as much as possible. For some, they take moved to the RDF considering it consistently cleans the screen to prevent those fine particles from returning to the pond. The expectations of your sieve actually depends on your level of effort in keeping it properly cleaned. If you flush it in one case a week, you can't look crystal clear h2o.
Featherbed is KEY! Awesome.....
I think the Zakki sieve (and all sieves for that thing) are actually consider as a "kickoff" stage filter. I personally would not run a sieve without having both a fines filter and bio later on information technology.I utilise my sieve to get the larger debrie out of the water column before the water enters my fines filters allowing then to function improve. My BD feeds the zakki (1st stage/mechanical), and so goes to two 55 gal fines filters (2d phase/mechanical/some bio), from at that place goes to my shower (3rd phase/bio).
The bulk of the time I only need to affluent my sieve a couple times a week Only, I as well rinse/flush my fines filter barrels twice a week forth with water changes. Keeping the fines filters clean is what gives me the h2o clarity/quality that I want, the water truely looks like liquid glass.
