I have had my tank for 3 years, recently took all fish out for Ick. I have had 6 total fish back in there for 3 weeks. My lights are radion gen 3 pro with red and green cut down and total light time of 8 hours,I run a skimmer, ATS, dose vinegar. Change 15 gallons a week with rodi from a spectrapure I have had for 3 months with 0 tds. I feed LRS fish frenzy daily. I keep getting this algae on my sands and rocks. Any suggestions? Considering going lights out for 3 days. Thanks.
