My last thread I brought up this accumulation of white filament. I wasnt able to bring up a picture because I had just cleaned the tank, but I did mention that after after awhile it comes back. Well... it's back unfortuantly

. I've been doing 50%water changes every Saturday. I still haven't gotten any type of snail yet.
This what i was talking about.
Also, I have another question. I bought a 3 gallon wisper filter for Auron because I was worried about tough currents pushing him all over the place. I did have elite mini, but it was primitive and 6 years old. The thing is... it doesnt move the water at all! Should I go the next step and get a 10g wisper?
