Hey everyone newb here, I started a 30 gallon saltwater tank on 9/02/03 it is now about 17 days old. I have just recently since the 15th day started to grow some brown-red algae stuff growing on the substrate. But i have not seen any spikes on my levels, NH3, No2, or N03, my pH is 8.2 and spec grav is 1.023 temp 78 F. i have two damsels and 4 lbs of live rock. Is there some thing wrong with my cycle or do i just need to be more patient? Thanks
