So i have a 20 gallon reef tank and it relatively new (about 6 months). within the first 3 or 4 months my tank exploded with diatoms which as i understand is very normal. About 2 weeks ago i started seeing another bloom starting in one corner of the tank. I readjusted the flow thinking maybe it was due to low flow in that one corner but it seemed to make it worse. I have re-adjusted the flow back to how it was but the bloom is getting bad. I'm wondering what other than time can be done. I was doing weekly 40 percent water changes but that hasn't seemed to help. What if anything other than time can i do to make this go away? I feed every other day and only have 2 small clowns and a fire shrimp in there plus several frags. am i just suffering from more "new tank syndrome" and it will eventually die off? Will they effect my water quality or corals? Thanks for any help.....
