Baquacil CDX to Chlorine conversion

[Watermom]

Hi Warrior! I'm sorry you didn't get any replies to your initial post in this thread. Somehow I didn't see this post until today. Sounds like you have been doing your homework and doing a lot of reading on the forum. I understand your worry after reading about reese and aciam's experiences. Those two were strange cases. We've helped with many conversions through the years and haven't come across cases like those before. Weird that they were both the same time period.

Keep hitting it with bleach. The more often you do so, the faster the conversion will be done. Never heard of the cottage cheese part before.

People can swim but should wear old suits and be extra diligent about watching swimmers in cloudy water.

Thanks Watermom for the reply. To continue from above at;

noon fc=8.0
cc=.5
ph=7.2 oto
added 364 oz of bleach

2pm fc=9.5
cc=.5
ph=7.2 t
added 182 oz of bleach
added 6 oz of borax to try and raise ph slightly......does it suprise you that it dropped from 7.8 during this process?

Then we had a swimming party & it was great. I never added anything to the pool the rest of the day & night. This morning at 7am fc=0
cc=.5
added 642 oz of bleach

at 11am fc=2.0
cc=.5
ph=7.2
added 546 oz of bleach

I do have a few questions though.

1....I can't hold any fc numbers, do you think it's time to add stabalizer to raise cya?

2....I think you will probably tell me it's too soon to try the step by step to lower TA, but should I add more borax to raise ph?

3....The water is still a little cloudy, maybe because of splash free bleach or high TA. I still have a lot of splash free I would like to use up if you think it would be ok?

Thanks to everyone for sharing their knowledge here on this forum.

It's not time to add the stabilizer until you're able to hold FC overnight (sundown to sunup before sun is on the pool). At that point, you need to change out your filter media, and THEN add your stabilizer. Also, with the pH at 7.2, I would leave it alone for right now.

I also would not use the splash-free bleach--can you return it and exchange it for regular, generic bleach? The splash-free part means that there's been something added to change the bleach--and additives usually create problems in pool water.

I'm sorry that we were late getting to this thread--I somehow missed it until today, too. ;(

Thanks aylad, I will wait with the stabilizer and try to exchange or return splash free bleach.

To pick up where I left off at 11am above, I did not add any bleach after that as we were swimming.

at 7pm fc=0
cc=.5
so I hit it hard with 728 oz of bleach

at 9pm fc=23
cc=.5
wow, no bleach added

today
at 6am fc=16.5
cc=.5
no bleach added.....pool really starting to clear up

10am fc=8.5
cc=.5
ph=7.4 Taylor
added 278 oz of bleach

1pm fc=6.5
cc=.5
ph=7.2 oto
added 364 oz of bleach

You're doing great! Keep up the good work!

Someone please help me understand this. (and please understand, I am not trying to troll, I am honestly confused).

Bleach at Walmart currently cost 2 cents an ounce and according to my calculations for GBWARRIOR's 13,500 gallon pool he has spent approximately $192.00 for bleach.
I am located in Lexington North Carolina and have contacted Davidson Water, Inc to determine the cost to fill a 13,500 gallon pool using my garden hose. Their reply: 59.30 TAX included.

In my situation (at least) would it not make more sense economically to drain the pool, change the filter medium, fill the pool and then begin the BBB method from scratch?

[PoolDoc]

If you can drain and refill for $60, that would be MUCH easier and better.

BUT! (And this is a great BIG "but")

BUT, many pools can NOT be safely drained without professional help, and often can not be drained even then.

+ In ground liner pools can NEVER be strained without special prep, and usually, professional help.
+ On-ground liners can sometimes be drained, but sometimes they collapse. If the liner is old, it will often tear, rather than stretching back into place.
+ If there is the smallest amount of water in the excavation of an fiberglass pool, it will float out of the ground!
+ If the ground is WET, even a concrete pool will float!

And . . . all of those outcomes will cost you way more than $200 in bleach! So, be careful.
