Ive seen this algae cover the tank and within 2 days of noticing it i started up the UV Skimmer. seemed to be working at stopping the rapid spread. Then i had a alk swing and within 6 hours i saw these white spots on the glass and back of the tank and some corals were ticked. i fixed the alk and most of the coral is opened back up except a hammer and frogspawn. I was wondering if anyone has a positive ID (i think its diatoms but i could be wrong) and if they have ever encountered whats goin on on my glass. also can this effect my corals well being?
