this is my first post
i have a climbing FC and CC and slimy pool bottom and sides. i have spent a fortune in chemicals and really need to pair down and get simple.
the last test was 6/20 and these were the numbers
FC 8.77 PH 8.5 iron .2
TC 11.87 AK 88 Borate 5
CC 3.1 CYA 140
Last week the numbers were
FC 8.47 PH 7.9 iron .1
TC 8.52 AK 90 Borate none
CC .05 CYA 140

SWG 40,000 gallon vinyl pool multi speed pump that runs 8am to 1pm then 4pm to 11pm
salt is at 3100 (salt generator always reads "add" at 2700 on remote read so I use the pool store salt test)
last week they told me to reduce the SWG to 60% output
yesterday they gave me muratic acid and told me to put a gallon in over an 8hour period. reduce my SWG to 40% and gave me a natural chemistry product to clear the water(which is crystal clear and gorgeous anyway)
she thought the sliminess was from dead algae since the chlorine is so high
i think there is algae(mustard because of the yellow on the steps sometimes and i have brownish yellow stains on the bottom deep end that i cannot get out)
yesterday i bought a pool test kit(that only reads up to 5 FC which is useless to me right now)
poured 1/4 gallon muratic acid into pool and the pool clarifier.
tested last night and PH was down to 7.5(according to my new"kit")
ALK was 80 ....FC off the chart
I put in four 1lb bags of HTC shock and swim and three 1lb bags of dichlor from the pool store along with two chlorine tablets in the skimmer. these are all i had on hand and i wanted to try to get as much chlorine in the pool as possible because I think the pool is trying to fight off something which is why the cc is climbing.
please help
no one is swimming in the pool this weekend so I thought i would try to shock the heck out of it.
i will be gone for a week before i can get back to it.
i need to know what to do next.
I am having the water tested today before i leave and the pump will be running continuously for the next two days.(it has been running all night so far)
