Canister for Fish Only

  • We are currently upgrading MFK. thanks! -neo
So it's going to be fish only with live rock? Are you going to put the live rock in the canister filter, or in the tank? Do you have additional water movement in the tank (fans/powerheads)? Have you abandoned the idea of the protein skimmer altogether? I would say that if you're going to attempt to not have a skimmer, abundant live rock and abundant water flow through that live rock is crucial.

I ran a 75 gallon on a Marineland C-360 for two years with zero Nitrate before I upgraded my system. I also had a hundred pounds of rock in the tank, and ran a skimmer. 2 Koralia powerheads worked inside the tank to move the water through the live rock. I also stocked very lightly, and performed regular water changes.

So, it can be done, but only with the presence of lots of rock, lots of flow. And the skimmer would definitely help, but if you've ruled it out, then you'll have to try and make it work without it.

What size tank is this?
 
if you're only keeping one fish then pretty much any canister (tank size dependent) would suffice really. As long as the water turnover is sufficient for the size tank you're using (generally ill always buy a bigger filter than necessary to give me legroom.

EDIT: my bad didn't see this was marine section ;)

My tank is 78 Gallons.
I'll probably get XP3 for canister.

I would get a protein skimmer but I'm really turning salt to house a dogfaced puffer.
I'm a student so I'm on a budget too.
On top of that, I need as little clearance possible between the tank and the wall.

So can it be done with a powerhead, canister, and liverock?
 
This is really true. Do a little research on what Live Rock is going for in your area, and add that price into the filter, and the extra powerheads it's going to take to set a tank up like you're looking to do. You don't want to get halfway through, have the tank set up, and then get to the store and realize LR's going to be $300 or $400. That would be very disappointing!
 
I use a fluval canister for my FOWLR tank and it's great that extra mechanical, biological, and chemical filtration make a huge difference.

true, ^ but if your getting at least 5 times over with the canister and the powerhead's are doing the rest you'll be good.

hmm,

so 78 gallon times 5x canister filter plus powerheads?

Looks like I'll have to do something better than XP3 if I understood that right.
Salt requires money either way I guess, but damn, it looks so worth it.
I'm sure it is.

I'll do more research on the salt set up, thanks
