I should have come to y'all first. I didn't realize what I was getting myself into.
I had some staining in my pool probably due to organics, and I used absorbic acid to remove them. I didn't add algaecide to my pool, because I'm BBB and don't need it...or so I thought. That's just one of the many mistakes I made.
Now I'm not sure if my pool is green because:
1. No algaecide and now I have an algae outbreak.
2. PH jump caused by adding too much baking soda on day two, and the PH jump made my stain "re-plate" in the water. (<<---According to pool store.) I didn't use any sequestering agent because I thought those were just for metals.
3. An amazing amount of pollen dropping in the Memphis area. So much that I broke the handle on my sock-lined skimmer basket because of the pressure of all the pollen in the basket. I turned off the pump to get the basket out and yellow pollen started pouring back into the pool from the skimmer area. It was so thick I couldn't even see the skimmer basket. From my searches, I doubt this is what it is. Probably just a coincidence.
The water is clear and light green. Not cloudy. Not slimy. Doesn't smell weird.
Before absorbic acid treatment:
FC: >7 (I turned the SWG too high and didn't check for a couple of days.)
Didn't test for anything else.
Turned on the SWG. I began my spring pump schedule of 8 hours on from 8 AM - 4 PM.
Added 5 lbs. baking soda.
FC: in the morning 1-2 (About had a heart attack! I've never had my FC that low before!)
PH 7.4. Lower that I usually keep it so I added more baking soda 3 lbs.
FC 3 (I intended to leave the pump on all night, but DH turned it off.
Ph 7.8 I battle low ph so I didn't think this was bad at the time.
(Told my husband if he turned off the pump again, he could be responsible for balancing the pool from now on. )
Afternoon: Pool turned greenish! I tested the pool water, and then took it to the pool store for them to test. Our #s matched. They almost always do. My pool store has good testers and equipment. I figured it must be pollen.
FC: >5 (I said 5, they said 6)
CYA: 40 (I had been adding CYA)
Late-afternoon: pool greener. Panic sets in. Call pool store. They had told me to not to super-chlorinate or shock the pool because of the AA, so I called to make sure I couldn't. She said it is probably the stain "re-plating" and not algae, but she couldn't be sure. She said to add the algaecide, some sequesterant, and some non-chlorine shock. I'm going to the pool store today, but before I do, I wanted to check with y'all.
What do y'all think about this treatment, and what is non-chlorine shock? I'm such a BBBer that I don't even know other chemicals besides chlorine, baking soda, borates (never added), cyanuric acid, calcium, muriatic acid and salt.
(Also, the PS was shocked when I said I have NEVER shocked my pool. She was speechless. LOL! I let the chlorine get too high over the winter when I was lazy about shortening the # of hours the pump is on, and the SWG just kept plugging away putting chlorine in the water. That was as close as I ever have ever been to shocking.)
Pool is 26000 gallons, vinyl liner, Zodiac salt chlorinator, cartridge filter.
Thanks for your time!
