Not true. It will be rare for the typical Bleach treated pool here to reach salt levels equal too, or greater than those using SWG and they don't need draining for "high" salt levels. Because of Bleach use, and my well water, mine is actually one of those rare pools, but my CH level will force...

I want to emphasize to anyone reading this in the future. What Matt says about not using SA in a pool under any circumstances cannot be over stated. It's much too dangerous to have anywhere near your family or pets. I know first hand how quickly and badly it can injure you, and I could share...

Wish it was like that for me....:sad:

Only to give perspective, this is really not that much. Many of us in the South and Southwest would be extremely grateful for such low acid demand. My makeup TA is 130-140 minimum, and pH in the high 8 range. Indeed, some people have it much worse. Be thankful of your small demand, and be glad...

Some people have it, but most have to adjust. I wish I didn't but it's all in your makeup water...too bad for me.

No, this will not do. You must use an approved drinking water sanitizer. In Texas this is regulated by the TCEQ. We are a reciprocity state meeting or exceeding EPA drinking water regulations. Different brands of Bleach, and pure gaseous Chlorine are at least two approved sanitizers on the list...

Just pay attention and you won't hurt anyone. We have a few around, and some others with serious chemical or water treatment backgrounds. Some of those and many others will be very interested in the workings of such a facility. Keep them and yourself anonymous for sure though. You'll learn some...

It would be better, safer, and certainly more practical to simply mix a diluted bleach solution. His method simply isn't the best approach for more than one reason. Edit: My reply was intended for an answer to post #3 and not a rebuttal of Matt's last reply. As usual... too slow. :sad:

Welcome to TFP! Yes, depending on what else happens in the pool sure it's possible, and with less than 800. Scaling is dependant on more than one factor. Not assuming you don't realize that, but it needs to be said. I don't know the answer to your second question, but whatever that value is...

I like your approach Danny! N-Joy the summer and dump the stress. :party:

I almost always agree. There is no rush to add them.

Pretty amazing what people are doing with these little things. That looks pretty slick I must say.

Sounds like a terrible idea in that case then. Unless you like foaming, and increased FC demand. I'll pass. :D

As Matt said, if you have soft water, its a good alternative. Even helpful if you need a Calcium source, cost aside. I don't think we say this often enough but its just fine in many cases. Bleach is great, and the next best thing as an alternative to most sources of FC, but the cumbersome...

Re: Treated Low pH & Alkalinity w/ Baking Soda - Now "deposits" at bottom Excellent choice, and glad to hear you got it sorted. :goodjob:

Sorry, was just thinking FC! :hammer:

Also, 12 drops on the 10 ml FAS/DPD test would come out to 6.0 PPM, instead of 15 PPM.

If they don't react with acid, Im not sure what to suggest other than mechanical removal, but I know that doesn't sound appealing. It wouldn't to me, and I'm sorry I dont have a better answer.

Personally, I have seen this very thing happen to a Lady's pool I helped with. She called a couple of hours after we added Chlorine and we determined later it was Iron. Fresh fill in a large pool with City water and it made sense after we thought about it. Old town, and they were constantly...

When Chemical Engineers test swimming pools.

Just once I would like to see some pictures and hard evidence of what bad, or worn out sand looks like. Not one person has ever produced any that I am aware of. I'd also like to know what is done to determine that it is bad. Do they pull a sample and look at it under magnification to see if it...

Ill take the first. 1. WRONG on all counts. Has he been in a Chlorine Plant? Doesn't sound like it to me. 2. WRONG again. Dry acid adds Sulfates. And he is just wrong about the pH spikes. Sure, it CAN happen, if you're careless.

Rust on the outside would be there regardless of FC level, and Cya in this situation has no bearing at all. I would say that salt water will be more agressive in this situation for sure, but this is not a water chemistry maintenance issue. Not in the least.

Re: What pool chemicals should not be stored together? Bleach and Acid should be stored seperately. Also, dont mix different forms of dry Chlorine in the same containers or those used with others previously. For instance, you have an old bucket of Cal-Hypo, and another partial bucket of...

It probably is, but are you certain you need more? Most places in Texas have enough in the makeup water, but there are some that don't. I presume this is a plaster pool? How low is your pool and fill water CH?

Given the pool type/situation, I too think the CC count is more than plausible. I obviously have no idea what they plan, but I would think MPS would be unlikely due to cost factors. That's being presumptuous about their budgeting motives to be sure and ignorant of club pool management as well...

The high FC is changing your TA test color, and your pH test as well. The FC is very excessive especially in the likely case where there isn't any Cya/Stablizer in the pool. I won't say its going to cause anything drastic, but I wouldn't suggest swimming in it. For an indoor public pool, it is...

At 8500 gallons, cooler temps, and shorter days this will be a pretty easy go once you get ready to start. Good luck, and keep us posted.

Although I dont suggest it either, the answer is yes. Even brand new drums of 12.5% have just as little odor. This was a shocking revelation to me many years ago, but its absolutely true.

In our experience, no paint holds up long in the pool environment. I think it's less the chemicals and more that there are just inherent problems with painted objects constantly wetted/submerged in any body of water.
