    How to add CYA?

    I know this is an old thread,but I found it helpful so i thought I'd post a pic of my first attempt at adding "stabilizer"/cya to my pool. My wife doesn't know i raided her sock drawer :) Thats a broom handle holding the 2 in 1 hose in front of a return jet. Its only holding ~2lbs.

    Noobie chemistry question

    Changed my mind about the pics, no one wants to see an old swampy pool. I'm really surprised how clear the water is now. Today the sun is intense so I had an umbrella shading a section of the shallow end where my daughter and I were hanging out. My torso was above the water and shaded, but my...

    Ya got me....:cool: if only I could use photoshop! I'll add pics of what the pool looked like when we bought this place. It was areal swamp, at night the bats would swarm above it eating the bugs. Thanks a lot for the help. - - - Updated - - - Wait till I post pics from two years ago...

    Sand filter and chlorine burn rate

    Thanks. I'm going to clean the sand soon. I saw a YouTube video that showed the procedure and I'm very curious to see what's in there.

    Yeah, it just started raining here, guess I'll wait till the a.m. for pics. My old concrete deck isn't very photogenic without sunshine so it's all good...

    Sand filter and chlorine burn rate

    This may be a dumb question: If organic matter in the pool eats chlorine and the sand filter catches organic matter, will a dirty sand filter (say one that hasn't had the sand cleaned in 5 years) increase the burn rate of chlorine as the water moves through it? I suppose it must, but after...

    Noobie chemistry question

    So yesterday the FC went from 18 to 9ppm during the day. My pool gets a lot of sunlight during the day, so from what I've read on this forum that burn rate is normal. I got the FC back up to 18ppm and it was still 18ppm this morning. The water is very clear and the C.C. has been zero since the...

    Noobie chemistry question

    Got the pool full after work yesterday and the cya is between 40 and 50. Last night I was getting a consistent 40 when i measured , but this morning I tried a few times and got varying results. Light reflecting off the water in the black dot beaker is the problem. My plan last night was to add...

    Noobie chemistry question

    Yesterday I decided to drain some water. I drained ~22% out, I didn't want to drain much more, since the liner is new and I didn't want to cause a problem. Anyway, I almost got the pool filled back up by this morning. I let the garden hose run all night but only with the valve half open so it...

    Noobie chemistry question

    At 6:40 am today the F.C. was 5.5 ppm, the test has .5 ppm accuracy so I'm gonna say no chlorine was eaten overnight. So I guess the rain messed up my first attempt at the overnight night test?

    Noobie chemistry question

    I wasn't sure if you had a special "cup" marked at 10 oz., or if it was a typo or powdered chlorine or what, just thought I'd bring it to your attention. ;) Today at 6:30am my F.C. was 7ppm, at 8:30 pm it was 5ppm. My pool is on the south side of the house and gets direct sunlight basically all...

    I just looked at what was remaining in the jug from last night. Instead of adding one gallon I added 1.5 gallons. The jug is 2.5 gal and I goofed...

    Noobie chemistry question

    Thanks for the advice. To get 50 cya I need to remove 17%, to get 40 cya I need to remove 33%. My pool has a shallow and deep end and the deep end is an uneven shape, the sides slope. So if the shallow end drops from 3' to 2', can I assume I've drained 1/3? Btw it's raining again so the slam...

    I use p a p , but ace is only 1 mile away from so I'll consider them next time. The water looked great this morning and we didi go swimming. I'll start the slam this evening. Thanks

    Noobie chemistry question

    Ok, I checked the f.c. 15 minutes ago and it is at 9.5, so I lost 1.5 ppm overnight. Should I SLAM the pool?

    Noobie chemistry question

    Confused now..according to the pool math, one gallon of 10.5% chlorine should have bumped me up to 5 ppm. I added the gallon and waited at least two hours with the pump running on high speed. The drop test showed 11 ppm. Do need to wait more than one hour after adding chlorine to test?

    Noobie chemistry question

    Ok. Thanks. I added 1 gallon of pool store chlorine after the big down pour stopped and bumped up my pump to high speed for two hours, after which it was programmed to shut off. Right now the rain has slowed to a sprinkle so I'm going to test the fc and test again in the morning. Rain chance is...

    Will rain affect the Overnight fc test? It's still raining , but I'd like to do this test over the weekend. Thanks

    Thanks for the comment. My cya is at 60, the numbers are in the first post. I'm also in Tallahassee, nice and cool today huh?:crazy: I'm going to do the OCLT test tonight/tomorrow a.m. My cc is zero and the water is clear so that's two out of the three SLAM passing requisites. I'll post the...

    Noobie chemistry question

    The green stuff comes and goes. This is my second season of owning the pool and the alge usually starts at the corner of the pool with the palm tree and after brushing and shocking goes away. Last weekend I had pump problems that caused at least one day of no filtering maybe two, before it was...

    Noobie chemistry question

    Thanks so much for the quick reply! I have read most of the articles in pool school, and was planning on stopping the puck poison :D. Funny how the pool store never mentions the cya side affect of pucks. I don't mind using the jugs to keep the water balanced. The p.s. is only a few miles away...
