[CATALYST]

Where are you getting your water from? I know that my algae starts growing when it's time to change the filters in my RO. The snails do help with the algae. For filter in my pod I use purigen, chemipure, a skimmer and a small piece of the blue foam for the overflow that I clean every day or every other day. You might try putting some macro algae of some sort in your tank too. Then it will eat up the bad stuff and grow instead of the micro algaes.
