I am getting a fair bit of surface scum on my water.
What is the cause of surface scum? Is it because the tank is open top? Anything to do with CO2?

Is increasing suface agitation/movement the best way to break it up?

It's a buildup of proteins. Surface movement will remove it but too much movement will decrease co2. You can get a protein skimmer if you have room in the tank.

Try focusing on CO2 more as eluded to, the more CO2= more O2 from plants= more growth, = less surface scum.


Plants leak the scum when stressed.
increase the CO2 and do some water changes and thing ought to be fine a in few days, week etc.
