I have not yet had luck with algae. I have tried cheato on several occasions and it died and wrecked havoc in the tank. Phos spiked like crazy killed some coral. If anyone has advice on using algae in a fuge would be appreciated. I’ve been told to try cheato gro. Going to do so and maybe get back with results. What’s a good light to use that won’t break the bank? Tried several.
