I have 2 of the Marineland 3-gallon Crescent tanks, they originally came with the adjustable
flow Tetra Whisper 10i Filter. One filter has finally died and the filters they now sell as the 10i are no longer flow adjustable & way too powerfull for a 3 gallon! (I emailed the maufacturer to complain but didnt get a reply)
I have a 3i Tetra Whisper in another tank but it doesnt work as well as the original adjustable 10i, have to change the so called "filter cartridge" more often.
Anyone have any good filter recomendations for this 3 gallon tank that you dont have to baffle & works well.
