Well, last year I found this forum and you guys helped me out immensely to get my pool from green to water that everyone we had over raved about how sparkling it was.
Fast forward to August of last year, baby was born, came back from hospital several days later and the pool was a green swamp again. Not enough time with the newborn so the pool was neglected, not used again, and.... eeek... not closed over the winter.
So, early this spring I get to work hauling piles of dead leaves, insects, sticks, etc. out of the pool water. I start up the pump, water spraying everywhere, I'm an idiot and my lack of pool closure resulted in the valve on my sand filter being ruined, sight glass shattered, and last year I was having problems with the pump, so I say okay I'm gonna just buy a new filter and pump and not mess with this. Buy a new pump and filter (Hayward Easy-Clear 40 sq. ft cartridge w/ 1HP Power FLO LX pump), have some problems but finally get it working.
SO - for the past 3 weeks I have been adding bleach, testing, adding more bleach, trying to make sure I've fished everything out of the pool, adding more bleach. The pool has improved a bit but it is still extremely cloudy and has a very slight tinge of green.
I nearly ran out of the DPD titratent (sp?) and CYA reagent so luckily that just arrived this morning from TFTestKits (ordered Wednesday night, arrived today, awesome turnaround!) so now I am all set to continue my eternal struggle with the pool.
My latest results have shown that the CC continues to drop but that the pool is still consuming a lot of FC.
One of the problems I have is I thought I had very low CYA so I bought some stablizer, added 2 lbs, tested a week later and now it is at least registering but just barely (the dot dissapears at the VERY top of the tube), is this OK during the shock process? Should I assume a CYA level of 20ish at the top of the tube like that?
I have been trying to hold the shock level at around 15-16ppm FC. Today I have finally had a day to continuously test and I have been testing and adding a bottle of 8.25% and when I test about an hour later the level is at about 16ppm. CC has been registering between 0 and .5 ppm
My latest results are as follows:
pH 8+ (I tried to correct this but hadn't yet read that the test is unreliable during shock process so I am going to stop adding borax/MA)
CYA 20 ? (dot dissapears at very top of test tube)
TA 90 ppm
Questions are - should I assume 20ppm CYA, and can I leave this alone until I am done shocking? I am trying to follow the CYA/Chlorine chart but the fact that the reading is
super low left me wondering what my shock level should be.
Is the water cloudiness a result of the pool still consuming chlorine? I have been cleaning the cartridge filter at least once a day and sometime more than once to make sure the filtering is working as it should.
My thoughts are that I haven't been adding enough bleach, but, it also seems that with such a low CYA the shock level of 15-16ppm should be more than adequate.
Your help is greatly appreciated, I've been beating myself up with all the problems I've had trying to open the pool up (that'll teach me to not close properly) and the wife
just this morning pulled out the dreaded "Let's bring a sample to the pool store" !! so I am trying to make enough progress to fend that off
