Not having a great success rate with the AA treatment as described here in the forums. Even when the vitamin C tablet works fine, the AA just isn't taking the stains off consistently, even with heavier than recommended doses. I sell a little brush that hooks to a telescopic pole. It looks...

Not worried about filtering them, worried about sequestering them. I was told by a tech for the other sequestering agent that I sell that "it's not very effective for iron, but works great for copper." Wondering if I can sell the anionic polyacrylamide or if I need to stock something else.

This is the main ingredient in a stain and scale prevention product that I know of. Does anyone know what it is, how it works, whether or not it's effective? Is it a chelating agent for iron/copper/manganese? Thanks again. Next paycheck, becoming lifetime supporter. Unless my truck...

The manufacturer's directions on a certain AA product that I know of says to balance the water to 100-120 TA and 7.4-7.6 pH, along with 0 chlorine, before starting the treatment. But it's actually more effective to lower the pH to 7.0 or 7.2 before starting, right? The question is, if your...

Manufacturers of chelating agents are pretty consistent with the idea that metals can be filtered out after a sequestrant has been applied with a DE filter or a sand filter + cellulose fiber. Is this a total myth or is there some accuracy to it?

I called Taylor today to finally ask them why they recommended a minimum CH level of 150ppm for a vinyl pool. I spoke to two people before finally being directed to a third. He said that even if the calcium didn't come from the vinyl, the water would try to pull it from somewhere. I said that...

Can someone explain why chlorine is a more effective disinfectant in a lower pH environment? Technical is fine, I've been brushing up on my chemistry for a year. But a subtitled description of what's happening would be fine. Basically, if you you have a swamp with a 25 drop base demand, is...

I'll have to make sure that my ammonia test is still good. I buy those out-of-pocket. Thanks all!

That's a good theory, FPM. It's quite common that someone whose last test shows the 60-80ppm CYA level that I recommend comes in the next spring with 40% salt loss (we had a LOT of rain and drain this year) and 100% CYA loss. The FC levels track reliably but the CYA levels do not. So this...

Situations just like this. I don't doubt the math. I've spent some time learning and understanding the chemistry and the math. There just has to be something I'm missing.

This is for chem_geek or anyone who wants to chime in. Coming into an unusually warm Spring after an unusually cold and wet Winter in GA, I've had a lot of SWG customers come in saying, "Yeah, the pool is a swamp." Well, their salt level is 1600 ppm and their CYA is indistinguishable from...

Duraleigh, Sorry, I was unclear. I didn't mean how much bleach was required to clear up the pool, I meant how much it took to reach my target of 30ppm. Anyway, I didn't mean to ruffle anyone's feathers. Liquid chlorine is great. I just think that in a large number of situations, the...

Oh yeah, I have no problem trying to convince someone that some rock-shaped speakers will impress their friends =). Because they KNOW they don't need it. But I won't sell calcium chloride to someone with a vinyl pool or phosphate removers to someone who has a SWG and brings their water in...

Mid-Southern GA. Never used anything but Clorox brand from Kroger and Wal-Mart. In the first case, when I first got converted to BBB, I was testing every 45 minutes or so and came out with a max percentage of 4%. I was trying to prove a point and it took days and a lot more bleach than was...

Well, in my market, the CH comes out of the tap at about 30ppm. Adding calcium here is either beneficial or harmless. My point is that the cost vs. convenience idea simply doesn't work out in some regions. For a lot of first-time posters, regardless of whether or not they have a vinyl or...

chem_geek; You have no idea how much you've helped me these last few years. I hope that whatever you're doing, you're making a ton of money. And you're exactly right. I present everything in a cost vs. convenience way. The stupid thing is that even if people choose convenience over cost...

Alright, so I've never recorded numbers. Theoretically, bleach from the grocery store should be 6% active sodium hypochlorite. This should make bleach about 63% the cost of the 73% cal-hypo that I sell in my store. I've done 7 swamp-to-pool conversions pro-bono for the sake of knowledge...

I just wanted to say thanks. I'm going into my third summer working at a pool store company. I've followed this forum constantly through the whole journey. Here's where I started: if-you-have-the-time-a-hypothetical-t12484.html Strangely, I have the lowest average per customer sale...

Thanks chem_geek. You remain the man.

I am hoping that someone could explain the "once a bromine pool, always a bromine pool" adage a little further. An indoor pool, drained one week ago and re-balanced. Bromine tablets are dissolving in a commercial-grade chemical dispenser. However, the bromide salts used to create a...

Nice! Now throw some dichlor in my eyes and disappear in a mist! Internet pool ninja masters =/.

All other considerations aside... Pound for pound, which is the more efficient oxidizer between chlorine and monopersulfate? If you literally need a pound per pound reference, think 73% cal-hypo.

I'm surrounded by veterans that insist on first-hand experience with vinyl damaged by untreated soft water. So I'm going to put my employee discount to good use and design an experiment. Unless you all tell me that it's not feasible. I'm not looking to publish a paper or anything - just for...

As always, thank you. I know that helping pool stealers is not what the site was intended for. I intend to become a supporter in a couple of weeks - the info here and the help of you nice people has easily made my life $30 less difficult! And if its any consolation, I feel confident that...

JasonLion - I had him lower the PH to prevent the stains from re-appearing, as described in a post here on the forums about the AA treatment. Was this a mistake? Likely there is plenty of acid left in the water, so what do you think is a good strategy for introducing chlorine via dichlor...

Hello, all of you inexplicably friendly folks. I work in a pool store and had a gentleman come in at closing time tonight. He started a stain removal treatment on Friday afternoon. I didn't sell him the chems (his pool store was closed) but he is sure that the stain removal product was 100%...

Thanks guys! Sounds like I should just stick with the Poly. This is what I've been using all along, per chem_geek's initial recommendations. Glad to know that it was the right call. I do make sure to stress to customers that diligence is required. Advising people on how to spend their...

Howdy! Hoping for some advice from the experts. This question concerns customers who have very high CYA levels (unfortunately, more common than values that are in range.) Which product is best to recommend as an algae preventative? I have had VERY little success convincing people that they...

Ah, okay. I figured that 80 lbs wouldn't be near enough, but I didn't even know that the meter was measuring anything other than salt, and I use the thing every day. Does this mean that it would be beneficial to overshoot on salt when using the meter to gauge how much to add? Or do the...

Howdy Wild Duk. Did your friendly pool store employee use a beige cylindrical electronic meter when testing your salt levels? Also, was he incredibly charming and good looking? If you answered yes to both of these questions, then the salt reading is accurate. Many of the chemicals that...
