thanks,just got off the phone with the discuss geek and he thinks it was a lack of o2 in his tank,with his discuss he already has the temp so high and was'nt running any o2 at night and leaving it running straight for those first few days,lol, he said he found a o2 test kit at one of or shops in town,and was getting an extremlly low read three time in a row,he took the whole system apart out of anger and now has a huge air stone running,lol he said that he had never seen such a change in the plants in those few days with co2 but now he is scared,I told him to fix the problem and give it another try,but he has about10-15 nice discuss and is scared to risk it again atleat until they are all acting normal,maybe he should drop the temp in the tank a bit,its up at 85,I know the discuss like warmer water but wouldnt they adjust to 80,that would be better for the plants too right,any way I may try and buy the system from him,so if I do you will be getting alot more questions
