I have had this tank for over a year and a half. I recently changed the aqua scape with Marco rock around two weeks ago. I went on vacation for 5 days and it was white before vacation and now it’s filled with some sort of algae. I had hair algae in the past, so I assume it’s partly this. But some of it is like neon orange and looks way different from hair algae. Any input would be appreciated. I will be testing phosphates tomorrow because I usually go to my LFS for testing, but I just bought the Hanna tester and it comes tomorrow.
