You know, like CYA takes about a week.

I've noticed that three reagents don't have expiration dates on them: R0010,R0011L and R0012. I learned a lesson in not watching the expiration date on the CYA reagent I was using one time and it caused me lots of problems. I just want to make sure that I don't use something that may have...

New to SWG and have kinda been chasing my tail with up and down chlorine levels (we're in 'winter' here in Hawaii with clouds and rain many days so sun not as intense). I had to shock it some time ago and put 'sanitizer output%' level at max but have been lowering it last few days to get...

When i do the calcium hardness test, the sample turns blue immediately. Don't do this test too often but when i did some 8 months ago, I've had to add calcium. When i plug zero into pool calculator it says add 48lbs of calcium. Really? Is there some other factor that's affecting this? I...

Filling completely empty pool with new water. Ran tests on tap water going in. Couple questions, I don't want to get into the same mess as I had with high CYA level: 1. Problem with Taylor K-2006 test kit is that when I test for CYA, the gauge on the low side only goes to 30. At 30 I can...

Pool empty and I'm cleaning it. Wondering if once it has been dried by the sun will it come back to life if you add water? Just curious if I miss a spot when brushing.

Not sure where to post this, I'll move it if this isn't right place. Not totally a beginner to this, been following your advice for about 5 years now but need some advice on what to do after pool has been completely drained. Ran into this problem because CYA was over 100 and couldn't get rid...

Not sure what I'm not doing wrong. Had cloudy, algae caused problem months ago. Shocked it. Fixed problem and returned to crystal clear. But, even though I kept the chlorine level within 2-8 over next week and a half, algae came back. Repeated the process but problem returned within a week...

Just added a bunch of CYA and ph has dropped to 7.0 (or below). I read in here that CYA affects ph but should I add borax to bring the ph level up or just leave it? TA = 70. Ben.

ph in the hot tub always seems to rise and I control it, but ran out of 'ph down' late one night and really wanted to get in. was just curious, is it dangerous to your body to sit in a hot tub with a ph of 8.0?

Looked around the site and can't find info on chlorine shock levels for the spa. Are there some posts somewhere I can read? Water is cloudy and trying to figure out the cause but thought it best to shock it first but not sure what the correct amount of bleach to use.

I have just added a spa to the backyard and already use the Taylor K-2006 for my pool. What additional test kit stuff will I need to test chemicals (bromine?) in the spa (Sundance 780 series Chelsee model). They gave me strips but don't think I want to use 'em. Thanks, Ben.

Thru this site's advice, I've been very good at keeping chem levels up to your recommendations. I test every three days and typically add 1.5 gals of clorox every 2-3 days and MA every 3 weeks. Water is never cloudy and I don't have any problems. But, and maybe I'm expecting too much, water...

Had to go with Swimming Pool Supply Company. :( And related question - is R-0871 reagent the same as DPD 1 or 2?

It appears that when you put in values in pool calculator it recommends you add chemicals to get to the highest value of the range (even if your values are within range). Is this what I should be doing, going after the highest value of each range (except maybe for ph)?

For 2 months now (since joining this forum) I've been following your lead and am happy that chemical balance has been under control and not one day of cloudy water (something that I always struggled with when I had pool guys do it). Water is crystal clear and I get all kinds of compliments from...

Every week I cut the grass around the pool and even though I use a basket to catch clippings, the trade winds, weed whacker and blower cause a large buildup of grass in the pool. It's almost more work skimming and vacuuming out clippings than it is to cut the grass. I have a slide and a diving...

I have the Taylor K-2006 kit and love it except for the CYA test. Just seems I get different readings depending on lighting, my eyes, bubbles, exactly when black dot disappears, you name it. Is there another test kit or process that does this easier?

Guy at the pool store tells me that it's better to use trichlor instead of bleach because bleach is only 6% which means I'm adding 94% of something inert. He contends that this 94% of something else will eventually bring the Total Dissolved Solids (TSA) level up to the point that only draining...

Heavy rain today and pool has risen a couple of inches. I have been testing daily until I can get everything stabilized but just curious, will this affect my numbers?

FC in the morning was 7, twelve hours later it's at 0. Now, CYA level is still at zero because I just added it a few days ago and it's slowly dissolving thru socks and I think you said it takes a week or so to register so maybe it's not helping to keep chlorine in the water (and it was a fairly...

Wish I had read the little warning around the pool light that says, 'Only turn on light while submerged' BEFORE I was draining the pool and turned on the light to see how low the water was at night. Quickly blew the 500w bulb...and they aren't cheap! Who'd a thunk the light needed to be...

Started on new journey with me doing the pool maintenance...with this forums help![attachment=2:3fsowf5o]Pool1.JPG[/attachment:3fsowf5o][attachment=0:3fsowf5o]Pool2.JPG[/attachment:3fsowf5o][attachment=1:3fsowf5o]Pool3.JPG[/attachment:3fsowf5o]

This is a continuation of another topic I started but thought it best to start new one. I replaced ALL the water in the pool to get rid of high CYA level (200ppm). I tested new water and here are results: FC = 0 pH = 7.6 TA = 60 CH = 50 CYA = 0 Assuming these are normal results because it's...

I'm currently draining the pool per your recommendations to get CYA level out. Do you have any recommendations on anything I should do while my tiled pool is empty? One of the things I'd like to do is get rid of the white substance buildup on the water line tiles. One of the pool guys said...

Hi...my first post, thanking responses in advance. From Taylor kit test my CYA level doesn't even come close to 100 mark which, since scale is inverted, I'm assuming it means it's around 200 or so. Tested twice, same result. From what I've read here the only way to lower this is to drain and...
