As of yesterday I saw pin sized white spots on the glass of my tank- alot of them, but they were soo small I could barely see them-i thought it might be an algae growing or something similar. Well, tonight in looking closer and in a spot that the pump is not hitting and they are actually moving all around--even on the rock, just really hard to see. What the heck are these and should I be worried? Nothing else has been introduced to my tank near the time of these things and all that is in there is my cleanup crew that is now well outnumbered. Ughh I hope someone can ease my pain here soon lol
