What kind of algae is in my sump wall and on my heater?

I see hair algae for sure. Looks like green cyano on the heater and likely some diatoms all over. Make sure you have measurable phosphates and nitrates so you don’t get dinos.![]()

How long has your tank been running?
still relatively new... probably just finishing up some of the ugly stage at the end of cycle
few snails, water changes and some manual removal... will be good as new
this is in your sump? do you have water movement?
