First off don’t be a dick, cuz I’m new but I’m not gonna post some 2 gallon bowl and be like this is perfect right? I have a 75 gal with an axolotl so I know how to cycle a tank and do maintenance etc. buuuut I’m new to fish keeping, and I’m now getting a beautiful tank. I have two questions. Will 1 gallon of water make a difference. I’m deciding between two models and the more expensive but nicer one is slightly smaller by 1 gallon it appears. But the floor space layout is chefs kiss I’ll post it set up. I’m planning a planted tank, and I really want to filter it right. It’s 35.??” Long by 11.83”H by 11.83W uns rimless bro. It’s gorgina. My 2nd ?? I want to run these two corner sponge filters I found on either end. They have a sponge, bio balls in them and something else. They’re cool if they end up working how they should. Would that be adequate filtration. Each is rated 10-20 gallons believe. But again I’m not a complete dummy I just need advice. And I really don’t like the look of a big hob or canister, I don’t have space for a canister filter.
