Green spot and ????? Algae –what is not right?
Hello. Here is some pics of my problem. What is it and how I can fix it.
40gal Long. Light 1x6700K 32W,1x8000K 32W fluorescent on 4h, off 4h, on 4h
Temperature 77F,Eheim 2217, UV sterilizer – on for 10h night time.
Ferts-PPS Pro every day before light comes on.
I use to have air stone ON for 9h night time but there was high PH fluctuation and I stop it 3 days ago.
PH -6,5-6,8 , KH 6 , gKH 7 , Nitrite 0 , Ammonia 0 , Nitrate 20ppm , Phosphate 2pm , Iron 0.13-0.18ppm
Pressure CO2 1h before lights comes on 2bps - 25-35ppm
Why there is no pearling over the plants?
Do I have to put more light with shorter photo period or there is some other problem?
Please help me to have good looking healthy plants.
