hey guys.. i have these tiny whit dots, or specks i guess in my water, they seem to be concentrated around my HOB filter, is it just dirty? or do i need a uv sterilizer? i sort of remember similar threads like this suggesting that but i couldn't find any. im not too worried about it, everyone seems to be doing fine, im more or less curious as too whats causing it and how to get rid of it... i can try and get pictures, they're most lilkley to be cell phone quality thou..
