Hello,
First, here are the stats for my pool:
25K, white plaster, DE filter
Alkalinity: 90
PH: 7.4
CYA: 40
Chlorine: 1
I've been treating my pool for going on three weeks now. I did a SLAM, treated with black algaecide, did another SLAM and am adding a weekly maintenance dose of black algaecide. In addition my husband and I are brushing the pool twice daily hitting the most prominent spots with a SS brush followed by brushing the entire pool with a combo brush. The FC level is holding as are all other chemical levels. The problem is, the walls are now brown where the algae once was. Are these areas dormant algae waiting to attack when the FC drops? How can I get rid of them?
Also, will black algae survive a cold winter in a covered pool without light?
Thank you, thank you! I love this site!
