ok so i have read several how to's and watched a couple videos on sump pumps for both saltwater and freshwater tanks. I like the idea of not having all the room in your tank taken up by equipment.
I have a 5 gallon tank and a little 2.5 gal
tank. I am using the 5 gallon for my tiger barbs and algae eater. I built a canister filter out of a jiff peanut butter jar and it takes up a lot of room in the tank. I tried to make a smaller one but it didn't work out too well. I have found a piece of drift wood that is to my exact liking and with the canister and the drift wood and my plants my tank is getting a little cramped.
can i make a sump pump with the 2.5 gal
to nix my canister and free up some space for my tiger barbs? it should proportionally work, but has any body done something so small?
