I'm in SE Florida and have been doing TFP method for about a year and a half. Over the last spring either due to bad circulation or not staying on top of FC I had some algae start on the floor and corners of the pool steps (and along the auto cleaner hose). 15k pool with about 45 CYA
This last week I've been attempting to SLAM to clear the algae. During the week I could only add chlorine in the morning and evening. It would at 5FC or so at 6pm every day and I'd bring it to 16-17, double check/add if necessary around 8pm. After a few days and brushing the spots are gone, but I kept doing this all week since I kept having FC loss in the morning. CC during these tests was either non existent or .5 or less. Pump has been on 24/7 during this.
The weekend I went ahead and added chlorine throughout the day, last night bringing it to 19 FC. This morning I was at 15FC. 4FC loss overnight seems rather high considering everything mentioned. Water never actually got cloudy and I've cleaned the filter as well, the only thing I can think of is that the water is just too warm to hold it overnight (it is rather warm even early morning), but I don't see that mentioned anywhere.
Any thoughts?
FC - varies, 5-19
CC - <.5
PH - 8
TA - 80
CH - 285-300
CYA - 45
