i have received 3 different answers of what his brown algae is. My LFS said 1, another LFS said another so i am just confused as to how to treat. Any feedback will be wecome.
I agree. Looks like dino's. Take a sample and mix it up in a white cup with some tank water. It should break up and turn the water brown. Wait 30 minutes and see if it starts to string back together.
Dino is likely and you can start with a good siphoning. What water are you using ( tap, well, Ro ?)
Margarita, astrea and cerith snails will attack some of this. I have had great success using Phosphate rx and/or Red Sea PO4X to help battle this. Reduce bright white lighting if you can also,
By any chance, is your tank at or near a window?
I RODI water for my auto fill. No natural light hitting tank at all, i use the custom setting from the factory. I’m going to shoo-in out and also do a 10% water change as well.
