I had a green algae bloom and checked the chemical readings before slamming it. PH 7.3, TA 80, CH 100, CYA 50, FC 4, CC 0, water temp 80. Added bleach to bring FC up to 25. PH went up as expected close to 8. Brushed and brushed. Ran the filter. Checked with a DPD kit (a Taylor kit that only reads FC and PH). Checked in a couple hours and FC had gone down to 22. Next morning FC 20. Next morning 18. This was a few days ago and now FC down to 10. There is no biofilm or slime anymore, but the water is a lovely cloudy aqua color, and we can't see the bottom.
The robo cleaner picks up some greenish/brownish sediment. I was hoping all the dead algae would settle and I could vacuum it out to waste. But it isn't cooperating. Do I need to keep the shock levels up high for longer? And will it hurt the robo cleaner to run in such harsh conditions?
