How do you guys prevent surface scrum??
I'm looking to start 2 or 3 nano tanks, they will be in the 5.5 - 6.5 gallon range. My main challenge at the moment is figuring out how to get rid of anticipated surface scum. My tanks will be rimless and open-top so a clear water surface is a must.
I have a Eheim Skim 350 on my 50 gallon, I love it - best thing ever. But I was suggested in another thread that I can't use the Skim 350 as the sole filter. That said, Aquaclears - they can't prevent surface scrum can they??
The tanks will be heavily planted, low tech, low bio-load.
