As my household begins making plans for a major upgrade, though having a limited budget to do so, we are putting together a list of what we will need. Some things are not too difficult to figure (like how much substrate, and what lighting we will use), but having never ventured into the realm if "large" aquaria, the one area that I'm unsure of: filtration.
We have about narrowed tank size to something around 120-125g. This will be a planted FW
tank, that will primarily be home to angelfish. The intent is for the tank to eventually be pretty heavily planted. So how much filtration should we be looking at? One large canister ("700gph" Odyssea for example), two smaller-capacity canisters? Any point of an HOB
(like my current Emperor 400)? I know with the longer tanks like the 125, circulation/dead spots can be a concern (can be helped w/powerhead). I'm kind o leaning towards two mid-sized canisters ( thinking you still have some filtration if one filter has problems/breaks down). We have time, so no big hurry right now. Just trying to plan it all out so we can budget and not run I to too many unexpected "bumps".
