Okay, I've been battling this for a while and I'm getting frustrated. I have brown algae on the live rock and live sand and green algae growing daily on the glass. Can't ever seem to get a nice clean tank. Looking for suggestions!
I have a year old 125 gallon reef tank w/ 40 gal sump and skimmer. I have a yellow tang, a blue tang, a clown fish, a rabbit fish and two small cardinals and a purple headed dottyback. I have about 15 marguerite snails and three conch's as cleanup crew. Sandbed is about an inch thick.
I have an RODI that automatically tops off the sump. I have two filter socks that filter the returning water from the two returns. Two powerheads at the top 1/4 of the tank and strong aeration and circulation by means of a 1200 gpm pump.
I feed twice daily, pellets in the am and brine shrimp in the evening. All is pretty much consumed immediately. Some days I only feed once.
LED lighting in place which runs about 6 hours per day. (white and blue) If I don't turn the lights on for a few days, I don't get the brown algae which is like a dust on the rocks. As soon as I turn on the lights, within an hour, the tank is brown. It's almost immediate.
I also get this purplish color under the sand where the sand meets the glass.
Any help or suggestions would be appreciated!
I was told by the LFS to do 25% water changes weekly which I was then told by a group online not to do. I've tried both ways and it doesn't matter with regard to the algae.
PH is usually between 8.2 and 8.35. All other parameters are 0 with the exception of Phosphates which sometimes will be a little elevated but not quite .025 as tested. I have a bag of phosguard in the sump. I do weekly if not bi-weekly changing of the filter socks and cleaning of the skimmer.
What should I or should I not be doing? Am I feeding too much? Too much light?
