This is my 3rd year opening my above ground pool that I inherited when I bought my house 4 years ago. I always seem to have some issue on opening and I would appreciate some guidance!
I opened my pool on 4/19/20 and the water was pretty dark green. I could see the bottom. I balanced the water, vacuumed and added a starting kit from Doheneys (metal out, shock, algaecide, water clarifier). That didn't seem to do anything.
During the first two days I found the pressure in my DE filter went up 10 psi, even after bumping, so I changed out the DE. It was caked brown but still white underneath. Today (4/21/20), the pressure was back up, so I opened the pump to re-sit the basket and now now the pressure is only increasing by 6 PSI. (Not sure the filter pressure has any relation to my water clarity issue).
Earlier today (4/21/20) I added two gallons of liquid shock and have not seen much of a difference throughout the day.
My current chemical numbers are:
Alkalinity: 110 ppm
pH: 7.4
FC: 10 (kit only goes up to 10 ppm)
TC: 7.5 or 10... the color was hard to differentiate
CYA: did not reach 100 marker (so over 100?). Sample is very cold so I will re-test at room temperature.
Based on the reading I've done here and the high CYA level, it seems the SLAM process will be ineffective until I drain some of the water out and refill the pool. Is that true? How much should I drain? This might also explain why my pool is always so highly chlorinated even in the middle of summer!
I appreciate any help and guidance here.
(I will also be ordering the TF-100 test as I have seen recommended on other threads.)
