Well..just got my TF-100 today and ran all of the tests. We have been getting rain like crazy (from Hurricane Alex)...no sun for the last 2 days. My SWG is set for 80%. I have had to drain some water from the pool to keep from overflowing. My pool has scaling and also "had" algae on the bottom of the rock ledges-but water was and still is very clear. I think that I have gotten rid of the algae. My question is regarding the FC, CC, PF and TA levels. I added 1 gal of muriatic acid last weekend and reduced my PH from 8.2 to 7.2 (test done at store on 6/27/10). Today, my PH is back up between 7.8-8.2 (it was kinda medium-dark pink). What should I do first? Help!!
Tests from 6/27/10 (done at pool store)
cc: not done?
TC: not done?
PH: 7.2 (was 8.2 two days before adding 1 gal of acid)
Tests done today with TF-100
PH: hard to tell (between 7.8-8.2)
The pool calculator says pool has the potential to become scaling.
I have read the article on water balance for SWG, but wanted to know if I am done "shocking" for the algae and how do i reduce the FC level now? What to do first? I have probably taken about 4 inches of water from the pool since yesterday b/c of the rains..but the pool calculator is telling me to lower CH by taking 35% of the water out...How could this have changed so much in 1 week? Since last month I have probably drained about 32 inches of water from the pool (trying too get rid of high salt level) I clearly am over my head!! Any help/ feedback/ direction would be greatly appreciated!
