 Topic: canister filters
Posted: June 16 2004 at 3:44pm |

I just bought a few canister filters for cheep. I was wondering about there usefullness in a salt water tank. I know that you can run piggyback fitration and have good results, But what about a canister? Also if I had a drilled tank, can a canister work in an overflow style setup? Where it would take it's water virtically, through the overflow instead of sucking it out over the top of a tank?

I will just give my warning that your system will flood, bulbs will burn out, and things will take continuous maintenance... get over it.

As long as the canister was being fed as much water as it was pumping there would be no problem in the overflow...however I would not recommend it. In essence a canister filter is a closed loop and must remain closed to work properly. Unless you're sucking from the bottom/middle and not the top, then there is the possibility of breaking the loop and burning out your pump.
I use a canister filter for water movement and when necessairy (a lot lately ) mechanical and chemical filtration (e.g. filter pads and carbon). Otherwise I just remove them and let it run. (I use that instead of a big  pump for a closed loop as it's what I already owned, and have other plans for the $$$)

I don't think that I have ever had my canester run dry. I guess that I need to pull the feed end of the pump and see what happens. Do you run the canister over the top of the tank like normal then?

What is the expetation of the canister filter? Are you targeting a specific contaminant? Or, are you trying to just get rid of foaties? Possibly the more the merrier thought?
I would say that ensuring your pump is properly supplied, size your pump accordingly to the maximum volume capacity of the discharge side plumbing. Will you be using a pump on both sides? If so, make them twins, and you shouldn't have issues. Or, use a sumbersible where it's flooded.

what do you mean pumps on both sides? I was going to use at least one magnum 350 for mech filtration in general. Then powerheads for circulation.

I meant a feed and a return pump. Wasn't sure how you were setting it up.

Don't most overflows allow some air into them? From what I understand air+canisters=noise and  .
It could work though if the rate that water came into the overflow was the same(or a little more) as the canister's flow.
If you're running a sump mabe try running the intake of the canister from the sump and the output up to the main tank similar to what gonzo said.

so other than that it is still mechanical filtration as normal... good. flow is easy to adjust
