New member (although I've visited the site quite a bit for a couple years) and I'm wondering if I have an algae problem or something else? I had the pool opened a week ago and found murky, greenish water. It was tough to see the bottom of the deep end. I've had algae problems a few times over the last couple years so I assumed it was back. The guy who opened my pool put 4 pounds of non-chlorine shock in (which I knew would do nothing, but let him do it anyway). I didn't have time to SLAM it properly until Tuesday, so I didn't mess with it until then. Check the specs in my signature.
I tested the water Tuesday morning and here is what the numbers were:
FC = 1.5
CC = 2.5
CYA = 10
TA = 130
pH = 7.6
I also had the water tested at my local pool store which confirmed my numbers and also showed that the CH was 320 and phosphates were 0.
So... very little FC, CYA was way too low and TA was high. From reading on the site, I decided to tackle the algae first and start SLAMing the pool. I did add a gallon of liquid stabilizer to bring the CYA level up to about 25 (which still isn't good, I know). I started SLAMing and got my FC to 11 pretty quickly. I checked my FC levels every 1-2 hours, adding bleach when needed, which was just about every time until evening. I also had my SWG on super-chlorinate the whole time. For the OCLT test Tuesday night, I tuned off the SWG and tested about an hour later. The numbers for that were FC = 11.5, CC = 1.5. The morning numbers were FC = 10.5, CC = 1.0, so petty good, right? Except the water was still murky and greenish (although not quite as bad as the day before).
I turned the SWG back on (super-chlorinate), poured in another gallon of liquid stabilizer to bring the CYA level up to about 38 and added bleach to bring the FC up to 15. I checked my FC levels every 1-2 hours, but didn't need to add bleach the rest of the day. The FC level actually went up to 21 at one point so I took the SWG off super-chlorinate and lowered the output. For the OCLT test last night, the numbers were FC = 16, CC = 1.0. The numbers this morning were FC = 15, CC = .5, so really good, right? Except the water, while quite a bit clearer, was still murky and still a little greenish.
So am I being impatient or is there something else going on? Should I keep SLAMing the pool? When I've SLAMed the pool in the past, the water cleared up right away (much faster than I was able to keep the FC levels up and pass the OCLT test). Complicating matters is that since I've been testing so much over the past few days, I'm now out of FAS/DPD testing powder and drops and can't get any more delivered until Saturday.
Any ideas or advice?
