Hello again all,
So my pool was great until my SWG stopped working and we developed a mustard alge problem because I was not taking care of the water (boo for me)!
Since, my husband fixed the SWG and I keep doing the same thing over and over almost every week - shock with a 2.75 no phosphorus bleach, vacuum like crazy until it's all clear, raise the run hours of the SWG and Pump until things seem all clear. BUT, lo and behold, the kids don't swim for a few days and here comes the algae again!
I've forgotten how to use the FAD-DPD to test FC and I'm sure not doing this has contributed to my problems - but - I'm trying to get back on top of things before summer ends.
So, here's what I know right now:
CC Over 10 maybe - Very dark yellow but not orange - SWG running 9 hrs
PH above 8.2 - a dark hot pink (I added 16oz of muriatic acid 31.45% 20 baume' last week and yesterday and it's still high)
Salt strip reads 6.6 so according to the directions it's at 6250 (no high salt warning from the SWG and in fact had low salt warning two wks ago so added 1 bag)
CYA about 28 - just under the 30 mark - tops off the cylinder
TA - 120
I think it's in my signature but just in case it's not, I have an Intex Metal Frame 18 x 48 pool with an Intex large sand filter and intex 8110 SWG
I read how to SLAM it and plan on doing that 1st but I need to know how to test my FC again - I searched it but didn't find an exact answer.
I almost forgot - the water is very clear! Only the algae is there, clearly seen at the bottom and all around the bottom edge of the pool and IS more prominent in the shaded areas.
Thanks for your time
