I just got this tank from a friend about a month and a half ago and the diatoms just went crazy about 3 weeks after setting it back up. The tank has been established for well over a year. I got 2 oscelarous clowns a cleaner shrimp and a small goby, 5 astreas snail 5 nasarious and a few other inverts. Frogspawn, mushroom coral. Nitrates read 0 and haven’t tested phosphates yet but am using an absorbent media. Any tips to slow this down or should I just wait it out? Ps there does seem to be some more Coraline growing on the back glass
