Hello, I have a 125 reef tank with live and dry rock. It has been set up since May 2020. I do not have a sump. I have a Fx4 canister filter with ceramic media inside, HOB Octo Skimmer, 13 W UV sterilizer in tank, two Nero 5 pumps, I have a HOB filter with Phosgard and filter floss. I have three 165 watt Viparspectra lights 65% blues, 1% whites. I have an Aquatop 300 watt heater with the digital controller. I have been having a horrible time with brown hair algae. It was so bad a couple of weeks ago that it was choking some of my corals down and making them look horrible. It was all over my pumps, accessories and sand. I treated with Phos RX thinking I had high phosphates. I changed all of my RODI cartridges except the membrane. It only got worse. Then I started noticing I had red cyano on some of my rocks. I treated with Chemi-clean and turned the lights off for 48 hours. I also raised my temp to 82 which had been suggested to kill the hair algae. It was also suggested that I add an airstone to help my PH. All was cured and everything looked great for about a week. I do a 30 gallon water change every Sunday and wash out my canister filters about every 3-4 weeks. I even ran my skimmer air line outside for a week and I still have the large air stone in the tank. I use Reef Crystals for my salt mix. I have a Scopa tang, yellow tang, firefish, two pajama cardinals, multicolored goby, many snails and crabs and another clean up crew coming any day. I am using Hanna testers for everything except Nitrate. It is API (drops). I just noticed today that I have brown hair algae all over my sand blowing in the current. I am out of ideas. Can you tell me what I am doing wrong or what do you suggest I do now. Thanks.
My parameters are as follows today: Calcium 523, alkalinity 10.3, pH 7.8, phosphate 0.31, Nitrate 5. Also attached a picture of the algae on sand. Hope it is clear enough. Thanks again everyone.
