My tank is around 2-3 months old now and been through the initial cycle and diatom bloom. Was happy how easy it cleared up at first! But they are back!!
My rocks have started to go brown and green in spots, diatoms seem to cover a lot of the sand.
Tank is stocked with a few snails, 2 clowns, fire tail goby, coral banded shrimp and a royal dotty back (which I've not seen for few days) few zoas and a hammer.
I do weekly water changes of 10% and clean out filter sock.
I originally filled the tank with tap water but use rodi ever since initial filling. Could this be the reason for the return of diatoms?
