Thanks - I have a good test kit - I used it for the CYA. It's not cheap, though, especially since I just spent $60 on bleach - so "dark purple" is good enough for me until I'm closer to a chlorine level that I need!

CYA is now 60. Chlorine is still way (dark purple - way more than 10). I turned off the SWG - how long until the excess FC burns off - any thoughts?

Our pump runs 24 hours a day, and both our filter and our pump are oversized - previous owner's doing. I'll need to get a timer to save on electricity at some point. 2.5 hours later, and still way up on the FC (dark purple on my strip). CYA appears to be up. I think I am in the clear. I...

On the bucket test, what am I checking every 1/8 tsp? FC? How long do I wait? I've read several posts on the bucket test, but that part has not been clear to me. In any event, I just added 8 more 182 oz jugs (33ppm). I did a test in an area that I did not pour the bleach half an hour later...

2.5 times CYA? I'm going to need some more bleach! I had like 70 CYA for the SWG! I'm going to see if there is any FC this morning (last year something like this happened, and I was really discouraged, and then all of a sudden I had FC). If it is low, I'm going to go buy more bleach, I guess.

Hi all- Seems like the time of year when I need to lean on everyone's expertise. We just opened our pool, and we had the CYA to Ammonia conversion that others have written about. My numbers yesterday were: 21500 Gal. outdoor SWG pool 0 FC 4 TC/CC 0 CYA 6ish ppm Ammonia Other chemicals were...

OK, so its been a while, but here are the new numbers, verified by the pool store: FC 2.26 TC 2.29 ALK 121 PH 8.1 (ouch - probably from the refill, right?) CYA 73 CH 168 Saturation .59 Clear, no Algae So, my plan is to add 3lbs of PH Down, and up my SWG to 30% (it's been running at 20%). Any...

Update and request for more help... Pool size: 16x34 - 3' deep in the shallow, 7.5' deep in the deep end I drained and refilled the pool about 18" over the last couple of days. CYA (black dot test) shows at about 60. The strip shows a little more maroon than that, which implies a higher...

Update - 1. FC was 7 or 8 today (hard to tell - I need a better kit) - I actually dialed back the SWG a bit. 2. Pool water tasted salty. As soon as my new salt strips come in (pool store sold me defective ones) and I get a better CYA test kit, I am definitely going to be draining. 3. I...

Solar salt - that's good to know! I can get it at Lowe's, right? You are convincing me. I assure you that my hesitation is not that I don't believe you or the advice.

No delusions, just gun-shy given the pain I've already had. I'd have to drain 40% of my pool! My plan is to struggle along this year (CYA will drop as it rains) and do a big drain at winter close in Sept. and let rain and snow refill. If it is too hard to keep things in check I'll drain earlier.

I have a gal of 12% and 4 x 1.42 gal of 6%. Maybe I'll put some of that in in the morning if the FC levels aren't up enough.

So, I measured today, and all of my tests showed - miracle of miracles - between 2.5 and 4 FC. I even did a bucket test with 1/3 Pool, 2/3 tap and that showed about the same (when multiplied by 3) to make sure I wasn't bleaching out. So, either: 1. The FC was so high yesterday that it...

Thanks for the replies, all. I know the CYA is high, but I live in WV, where it rains all the time (rained all night), so I add a bunch of water and do a partial drain in the winter. My SWG manufacturer says CYA of 50 and FC of .5-1.5. Thus, I'm not too concerned about the CYA of 136, as I...

Not sure if this is the right forum, but my bottom line question is "what else can I test" so I'm posting here. I have a 23,500 gal vinyl pool with a high CYA - 136 (high, I know) and a new SWG. I would rather not dilute if I can - it will happen naturally with all the rain we get in the summer...
