Question about the OP who was putting bleach in every day or two and not following the shock process as described. When the FC goes back to 0 is all of that bleach wasted and are you basically started from scratch again? or are you making progress and getting closer to shocking the pool?
I was doing that for a bit until I found enough bleach to give a large shock.
fresh bleach in pool and brushing sides one day and bottom the next, third day vaccume.
I had so much CYA (310) I believe much of it went into killing off algae and mixing with the CYA.
but I had a SWG that was non-op, I repaired it and by the 4th week once SWG worked the bleach had a better
and longer lasting effect.
with a CYA level too high from tablet use, it is recommended to drain pool. I pay a sewer fee for just as much water
is used. but being in a area that gets a lot of rain at times I just drain off over flow slowly and will do that.
just North of me Nashville say they go 32" rain since 1st of year. I maybe got 10"...so I will vaccume and bypass
my filter out to the street so to speak, maybe 1" every time I get enough rain.
as for the 310 CYA number if you put that into the pool calculator it requires a enormous amount of shock/bleach.
I choose to get there the gradual way.....I thought it too much for my liner to handle without discoloration.
note: after adding about 30 pounds shock had almost a zero FC next day. 3 3"tablets were in my skimmer too.
there was no green in pool, it was FC at or near zero every morning or less than 0.5. (dirty or dark cloudy at deep end)
then afternoon when almost full sun added a 8.25% bottle bleach.
at then end of the week I might put in 4 or 5 bottles at once, again follow by brushing full pool.
I figured algae will never get a foot hold that way.
one more thing three weeks later the pool never looked green at all, no FC measured above 1.0 except the day after
the 5 bottles were put in...but short lived. I let the pool run 24/7 for a few days. backflushed a few times after
vacumming bottom to waste. it took a bit like help from SWG to finally see my 8' bottom clearly.
hope that helps. I did get my CYA down to about 140 now.
just wait-in on more rain......patience.....
FC10, CC 0.5, TA 120, PH 7.5, CYA 140 stable as a rock with my SWG running at 65%.
