when i save enough money i plan on making a better ATBA & filter. my turtle is 6 inches long & i have a 20 gallon long tank. I KNOW i need a bigger tank, but they're just too expensive for me right now (i do not work, i get a small allowance, & i'm a full time nursing student so i'm quite busy). when i finish making the ATBA, i plan on raising the water level as high as possible, so that she's has a lot of swimming room.
could anyone please let me know which filters are the best & CHEAPEST for a 20 gallon long? i'm trying to make do with what i have & i want the best for my turtle
