Hey guys so I’m running a fluval sea light on my 90 gallon tank. My corals are doing great I’ve seen some growth and haven’t had issues with any of them, the only issue I have is that brown algae is growing a lot in the tank. The tank is 6 months old and I recall after the first 3 months my algae issue went away but it suddenly came back like a month ago, it’s covered the glass and even the sand bed (also noticed Coraline growing on certain areas). Right now my lights run from 6am to 6pm 100% blue and 90% white. Then from 6pm to 10pm it’s just 100% blue, at 10pm it’s completely off. Am I running my lights too long? Should I only be running blue lights? I have like 5 turbos, a red tux urchin and a Diamond watchman goby to sift my sand ( haven’t seen him in a while) I’ve heard people say to use rodi, I’ve been using the boxed saltwater from my lfs for water changes and for fresh water top off they sell rodi water a dollar per gallon so i use that for my top offs.
