Good evening all. test results tonight:
FC 6.5
CC 0
TA 140
CYA 55
CH 50
PH 7.8
TF 100 TEST KIT
wATER has been crystal clear, but over the last two days have noticed some green spots at bottom of pool, not on walls, few here and there. tonight went in and bottom felt a little "slippery/slim". I brushed bottom of pool and could see algae cloud up as i brushed. Have been able to see from end to end under water until tonight....little cloudy under water once water stirred up, but still able to see bottom looking down into pool. FC has not dropped below 3. Filter running about 6hours/day. Temp of water has been 78-80. going to check overnight fc loss tomorrow morning. CYA has been 30-50. have raised the FC levels up, but not to shock level.
Can I have algae if FC has been adequate?
Recommendations of where to go from here?
