Hello, I am new to the forum and have spend many hour reading all the various pool school recommendations and a multitude of posts. On June 6th I opened the pool to find a terrible swamp. After much bleach (about 25 gallons) the water is now crystal clear. Then I could not get it to hold chlorine. Now I am losing 1-2ppm overnight of free chlorine. I cannot really do a SLAM, due to work and time constraints. One thing I should probably mention and am acutely embarrassed to say is that I accidentally bachwashed flocculant into the filter after the algae treatment. I called the company and they thought this would not really present any problems. They recommended a chemical clean WTO be safe which I have not done.I am still concerned as I can find no information anywhere about this particular error of mine. Anyway, the water has remained crystal clear, I bought the K2006 test and am waiting for it to arrive.here is my water chemistry for the last few days. Filter has been running 24/7 for 10 days. Backwashed three times before all of the readings below but only today has the pressure reading changed from a baseline of 19, today for the first time it is 25.
6/15 Tuesday : computerized pool store results:
FC .21
TC 0.4
CC .19
pH 7.4
TA 92
CA 526
CYA 23
Total dissolved solids 500
Phosphates 0
Copper, iron, manganese, nitrates all 0
Sat index .5
My results using k2005 test kit ( I just today received my K 2006 test kit) we basically the same, although I got a CA of 450 and a CYA OF 50. The chlorine at that time with the K2005 test kit in the evening after 726oz of 8.25/7.85 available chlorine ie Clorox, would test 10 but could have been higher since that is the max the K2005 test kit would read. By 5:00 am before the sun, it would test 0 FC and CC. This went on for 2 days then started testing 1-2 at 5 am. This is adding 726 oz bleach every night. The pool is in the sun the entire day, temps around 85-90 degrees.

I Received the k 2006 test kit which gave these results right after the computerized pool store result
FC 5
CC .05
PH 7.8
TA 110
CH 475
CYA less than 20
Questions:
1) what would cause my CYA to drop from 50 to 10 in 4 days. No water has been removed, I did add a small amount of water this morning, hard to say how much water added but the hose was only running for 30 minutes.
2) Any intel on the flocculant I sucked into the filter? It was probably no more that 25% as the vacuum would quit sucking quickly, then I realized my error and vacuumed to waste.
Any recommendation , information, experiences would be greatly appreciated.
I have read everything in pool school,all the posts I could find on CYA, ammonia levels, there is no information on flocculant in the filter.
Sorry for the long post, it's been a heck of a 2 week opening!
