Canister filtering a sump

  • We are currently upgrading MFK. thanks! -neo
I've had yet another idea.....
I have one new canister filter waiting for my new tank to be ready, and I also have my old canister filter which is filtering my old 140gal tank.
I was thinking about just using the 2 canister filters on my new build.

I want to use a seperate outlet feed for each canister, and have both returns running through one return 1" bulkhead and spraybar.

Or.......could one 1" bulkhead feed both canister filters??

Sorry, I don't know the brand of the canisters off hand, but the smaller one has 3 trays inside it and the bigger one has 4 trays.

Sorry for all the conflicting questions in this thread, but my filter knowledge is a big fat "ZERO".
 
We would have no idea without knowing what brand and model the filters are.
 
those are jebos i would not think 2 of those would be enough for your tank
i think they push around 325-380 each, but i think thats what there rated for so it might be less with media

if i was you i would look to push at least 1200 to 1600 gph back into the tank so i would think you need at least 3 1 inch bkheads for the shipon if each pulls 600 gph
but 4 would be safer as you cant pull out more then you pump is pushing back

your planning on keeping bigg messy fish so i would look to over filter
i like what people have told you so far
i think you will be ok with 3 - 4 1'' bkheads and a return along the top of your tank

Yeah, I know you are right, but I am just trying to cover all my bases before I finally decide which filter system I will use. I think I will be going with a sump, but I was just thinking out loud.
 
Did someone say sump?


Hooray for sumps!
 
OK, I have decided, I will go with the sump method, but have a question....

I will make an example....
My tank is around 280 gal, so an ideal sump size would be around 80~100gal. Whilst the sump is running I would say that only 1/3 of the sump has water in it at any time. So that's about 25~33gal of water.

My sump will be on my balcony which is a tiled sloping floor with a drain at the lower end.

So here's the question, could I then use a sump of around 40~50gal with an overflow in the sump connected to the drain?? If the pump stopped running for what ever reason the water in the sump would overflow and just go down the balcony drain.
Would the smaller size sump affect the filter funtion??
 
yes you could
but lets say the power went out and the sump overfilled and spilled 40 gallons of water off the balcony. when the power came back on your system would be 40 or so gallons short-- this might not be enough to keep water in you sump, the dried bio media will kill your bb and the lack of water could burn out your pump.. so you can set it up with enough filtration but i wouldnt do it

i would measure how far down your over flows are and find out how many gallons they can drain---that volume + at least 25 gallons should put you in the right ballpark for a sump size

and btw i would def. use a sump for a size that big

if you went with cainsters your setup would be alot eaiser and safer, but your gonna spend a ton more money,
another thought is pm NC_NUTCASE , he was talking about a pressurized pond pump and how its cheaper than the new fluval, maybe he can give you some details on that
