Just started two nano tanks last week using Tropic Marin Pro letting them cycle no light for 2 months or longer. What is with the foam with any or surface turbulence? Started skimmer after a week just to see how it works wow what a mess!

Any surface turbulence, splashing air etc causes foam.Not exactly sure where you’re saying your foam is coming from, but I think you mean your skimmer. They go through a break in period and it probably just needs to be tuned down.
Do you have a photo you can post? I’ve had foam build up in my overflow on an AIO.Any surface turbulence, splashing air etc causes foam.
