Thanks so much guy's, a update is due this weekend.
The first few weeks I had co2 24/7 with a high bubble rate possibly 4-5 bps while the AS was settling and leeching out the ammonia, mind you I did not do crazy water changes like many do with new AS, just one WC a week.
I have been running my photo period at 11 hours but I'm going to cut it back now because the stones started growing BBA hence the big cleaning I just did.
I think it may be due to the fact that I had blasted the Co2 in the beginning but had to cut it back once the shrimp went in.
I'm also experiencing some GDA but not too worried about that.
I find HC will do best with high light, Co2 and ADA AS as a substrate, you don't even have to dose that much.
