Yup

You're correct our indoor pool surrounded by the aluminum structure is around 1200 ppm salt. I will be bringing all this info to the owner at the end of the week so hopefully we will see a change. Thanks so much to everyone so far. -Brandon

Ok fair enough, semantics, it's not useless but it is reduced in effectiveness no doubt. Sufficient =/= ideal. As am sure you'd agree with what's been happening in my last thread with our method of chlorinating. We are sufficient, but not ideal. but even in the last forum thread link you posted...

And yes, other factors in the water have an affect on orp. pH being the biggest one but th and others having a much smaller affect. But that's still relating back to oxidizing potential. What happens to chlorine when your pool water is at a 8.0 pH? It does basically nothing. Cl in a pool with a...

No argument :) I think you are assuming though that we add cya at the beginning of summer and that's it. It gets maintained at 30 ppm the whole summer via weekly cya testing. So there is no constant adjusting of the setpoint. Just occasional additions of cya as needed. -Brandon

I am very much aware of this. But with water changes and back washing throughout the summer. By winter time I get our cya levels back to 0. We only run up to 30 ppm in the summer, which isnt hard to get rid of with the methods I stated. We've been doing it this way for 7 years now and trust me...

0 All due respect, orp doesnt care if its measuring a commercial pool or a residential pool. You stated orp sensors dont work when cya is present in the water, and that is incorrect. -Brandon

Sorry to butt in but this is not true. A truer statement would be CYA levels affect ORP readings. But not in the sense that would lead one to state that they cause them not to work. And they most definitely work on outdoor pools. Not all outdoor pools use cya. Orp is simply measuring oxidizing...

Thank you joyful, I dont see you coming off as harsh I want all this info. I very much care about my pools and this business that the owner has going here. I just want to improve things. The main being that I don't like me and my guys handling cal hypo. I am already against it I just wanted to...

Not sure exactly what you are asking here but there is no "system" in use here. We simply create our own bleach solution (albeit poorly) and use automated chemical feeders in conjunction with ORP and pH sensors to pump acid and Cl into our water as needed. The chemtrol get set to an ORP...

I will be buying the hypochlorite test you recommended. I am very curious about what we are actually making. All that I see specifically mention sodium hypochlorite but I imagine it would do just fine with cal hypo too correct? -Brandon

Thank you for the reply. The pH of the solution once it's been siphoned over is in the high 9s to low 10s. However we are just using city tap water to mix the cal hypo. In our case this is usually around a 7.7. So what you are saying if I'm understanding correctly is that the cal hypo will be...

Thanks :)

Additionally, I realize at 1oz to 1g of water is a low ratio according to what the cal hypo container suggests by a large factor, it's just even when weve tried to up the ratio to 2oz to 1gallon of water weve had massive amounts of sediment build up in the mix tank.

Quick history of our operation: I am NSPF certified and I run the bodies of water at a hotel/health club 1 33k gallon pool 1 75k gallon pool 3 spas 1300, 1300, and 1800 gallons. For the past 10 years we have been using cal hypo as our sanitizer for all of our pools. However, we do it...
