Been having trouble for a while passing all three criteria, the holy trinity, of the SLAM. (Clear water, CC < .5 and passing the OCLT.)
FC - 18.6
CC - .6
CYA - 40
I was SLAMMING from about the 25th of April to the 8th of May. Couldn't pass Slam. Decided to let the FC drop to normal levels. Changed to another source for liquid chlorine ( that's another story.) By the 13th FC was normal for CYA of 40 (about 7). Dropped PH to 7.2 and commenced to slamming again on the 13th.
Since then, maintained FC between 16 and 20. Brushing once a day. The ladder has not been in the pool. I'm keeping any debris out with an Intex over the edge skimmer, hand skimming and vacuuming to waste when necessary. Today I took apart the entire skimmer assembly and found a little "schmutz" under the lip. (See images on lid, on finger and wiped on paper.) Feels slimey/greasy. Cleaned the cover good with soap, water and liquid chlorine. I'll leave it off until tomorrow.
what to do? Stay the course?
thanks so much
