Why are the CYA levels for SWG pools recommended to be higher? http://www.troublefreepool.com/content/128-chlorine-cya-chart-slam-shock Non-SWG goes down to 20, SWG starts at 60. I'm at ~35 and deciding whether to increase that further or not.

11am - FC down to 13 - Added 75 oz of bleach to hold at 15

9:30am - FC is 15.5, CC 0 Making progress. Will hold it at 15 today and try the OCLT

8am - Added 3 more jugs of bleach (targeting 14-15 FC) - Added 2 jugs of liquid CYA

- 2am FC 14, CC .5 - 7:45 am - FC 4.5, CC .5 Adding CYA and more bleach

1.5 hours later: - FC level down to 4 / CC .5 or less - Added 6 more jugs of 121 oz 8.25% bleach - Brushed down stairs, tanning ledge and walls/floors

Re: A little encouragement for those with algae and new to B I bought 12 jugs at WalMart at midnight - checker gives me a funny look, I just told him "ever seen breaking bad?"

Posting updates to keep track of what I've done. - ruled out reagent failure by testing neighbor's pool for CYA - it was 60 - reconfirmed that mine was 0 - ph at 7.0 - FC .5 before beginning - Added 4.5 121oz jugs of 8.25% bleach - tested 1 hour later - FC 2.5 !!!!!!! - Added 3 more jugs of...

Thanks for the reply, I had read about the bacteria - wierd. As I'm not 100% certain it is the bacteria, is there any chance that the R-0013 reagent can go bad? I'm presuming the idea here is to a) kill the bacteria then b) SLAM killing anything that remains...

I added 242 oz of 10% clorine before a trip last Thursday. Came home yesterday to 0% and a cloudy pool (but not green) and bubbles from the spa spillover. Added another 242 oz of 10% last night, FC was 0 again this afternoon (was raining this morning and I didn't check). Tested CYA again and...

No algae at all and the chlorine I add keeps getting used up. Guess I'll keep adding! Sent from my HTC One using Tapatalk

Hi all, did the Ascorbic Acid treatment last Thursday/Friday - I used 6 lbs since the stains were really really bad. Since Saturday I've dumped 6 gallons of 10% bleach and can't keep the FC up. I did the overnight test last night it was 4.5 - 5 ppm, then this morning before sunrise it was down...

Nice pool! Another Flower Mound resident here, welcome!

I'm not an expert but you can buy a new one. Or, new house right? Do you have a home warranty? Sent from my HTC One using Tapatalk

If you haven't already be sure to clean your SWG. When I did it made a huge difference in the amount of chlorine generated. Also make sure the salt level is up or it won't make and chlorine. Sent from my HTC One using Tapatalk

Sorry it's on my pool deck the are about 4 of them. One has a wide rust ring around it like water comes up out of it but when I unscrew the top there is just dirt and mud in the hole Sent from my HTC One using Tapatalk

Makes sense, worth a trip to the store then to make sure I don't wreck the CYA and cause other issues. So a better plan would be to: - Add 241 oz of 6% liquid bleach - Add 49 oz of Muratic Acid (31.45% 20 Buame)

Hello from DFW area - lifelong Texan here, never lived anywhere else.

Thanks! Sold us on the house, along with a few other features. Since I didn't plant them I'm not 100% certain but they look like Italian Cypress to me.

First time dosing my (new to me) pool. Thanks to the help from this forum so far, I've calculated the size of the pool, purchased the TF-100 test kit, and tested a few times to get the results below. Before I "dose" for the first time, here are my calculations and plan - I appreciate any...

Thanks Richard. Makes sense. As a type 1 diabetic for 30 years I have lots of practice doing this with my blood sugar, I figure the pool is just another thing to dose and measure, dose and measure, rinse and repeat...

Thanks for linking to that tool BoDarville - very helpful (is that really you Burt Reynolds?) I calculated the following: Pool - 6.5 average depth (4.5 shallow end, 8.5 deep end), 17' wide, 36' long = 26,700 gal Spa: 7' diameter, 4' depth = 1,200 gal Total gal = 27,900 Sound about right...

Hi everyone, thanks for this forum, loads of information here. I got the TFT100 test kit so I have results to share and questions about those, but first I thought I should know the size of my pool. Previous owner doesn't really know (he guessed 35k-40k gallons). I'm including photos and...
