Two weeks fight with GW ( the chemistry, change of water etc.) did not bring the effects. Effects were worse yet, water got greener. Bloom started when I had cut a few plants. Macro nutritients were very low (N total - 2ppm, P total - 0,2ppm). At the beginning I raised level of NP- N to 15 ppm and P to1 ppm and I made change of water. Water ....continually more green, which brought me to fury. I was spending lots of time reading all accessible materials on APC & other forums - Tom Barr's posts inspired me particularly. Then, I made following experiment. I added to filter activated carbon and filtered by 24 hour to polish water (specially NH4) After I added oxygenated water (3% H2O2 - 50 ml / 100l) and changed 50% water in tank. Then I beck to routine fertilizing (N, P, trace)
Water became incredibly clear!
I hope that bloom never comes back.
Maybe it was by chance or maybe it works
