Re: Does Cal-Hypo's Low Price Undermine TFP's Focus on Bleac Just wanted to say thanks to all responders. I've been working with your ideas for a week now, and I've benefited from them all. A very valuable thread for me, though forum experts might see it as ridiculously simple. Thanks!!

I'm trying to make economic sense out of TFP's preference for bleach and I can't see it so far. Was BBB born in a past era when bleach was more cost effective? I looked at the great thread on Bleach Prices 2013, and it looks like everyone is struggling to make the bleach idea work. An older...

Re: Calculating pH Impact of Cal-Hypo, Bleach, & Other Chlor Plaster. So since we have really low CH in our make-up water I was open to Cal-Hypo. May still be. But handling that stuff is so unnerving. Noxious fumes when you open that big bucket, and you know years are being erased from your...

Re: Calculating pH Impact of Cal-Hypo, Bleach, & Other Chlor OK. Made the mistake of trying to buy sodium hypo from a pool supply. None of the stores I contacted had it. Of course they have lots of other products they recommend instead. AND they use the ruse that bleach is high pH and will...

Re: Calculating pH Impact of Cal-Hypo, Bleach, & Other Chlor The CYA test is a strange one, and I'm never quite sure I'm performing it correctly. But yes I'm doing it, and that little black dot finally disappears completely when the scale reads somewhere in the 30 - 40 ppm range. I'm rapidly...

Re: Calculating pH Impact of Cal-Hypo, Bleach, & Other Chlor Fascinating! Thank you both! We have low CH here (western NC), and there's a giant tub of Cal-Hypo in the storage room, so I may focus on the Cal-Hypo rather than the Bleach. Perhaps if I bring enough of that into play then I can...

The Pool Calculator's "Effects of Adding Chemicals" helps me estimate the pH impact of Trichlor, but not Cal-Hypo or Bleach. My 50,000-gal community pool uses a Trichlor feeder, and I'm investigating the possibility of reducing Trichlor usage and combining with Bleach or Cal-Hypo for a net pH...

Correct. With pool water it behaves as expected. For example, a couple days ago pH was low and I did a base demand test. FC 3.6 ppm CC ~0 pH 7.1, 3 drops base demand TA 60 ppm Base demand test behaved as expected. As I understand it, TA = 60 ppm is low but it's not as low as the make-up...

Recently purchased a Taylor K-2006 Test Kit, and can't say enough good things about it. As a newbie, I feel like I have a million questions, but the one thing I don't have to wonder about is the quality and consistency of test results. Tried testing my make-up water today. TH (30 ppm) and CH...

Yes. Minimal caking. Glad to hear it's probably OK. OMG the smell is potent. I'll take it outside on the hand trucks before opening. Thanks!!

Just saying thanks. I'm in a sharp part of the learning curve, and ya'lls advice kept me on track. Following JasonLion's advice, I adjusted pH using Soda Ash. Took two attempts, but the result was pH up from <7.0 to 7.4, and TA up 20 from 50 to 70. Now I see that, like you said, I can now...

Just had to take over operation of a community pool. There's no one to tell me the history of any of the chemicals in the storage room, so I don't know their age. There's a huge bucket of granular Cal-Hypo that's about 2/3 full, and I'd like to use it due to low CH. But can it be relied upon...

Yes, I am generally aware of the CYA issue with trichlor. I've been told that I might use trichlor in the feeder, and then add cal-hypo in the pool. But I haven't attempted this yet. Not sure how exactly, but I guess I'd throttle down the feeder a bit and add cal-hypo to reach target FC. Any...

Newbie. Have been handed a community pool in mechanical and chemical disarray, and I'm trying to recover the situation while keeping the pool open. When I stepped into the crisis, FC was ~ 0.5ppm. Turns out the trichlor feeder lid was jammed so nobody put any in. Fixed the lid and threw in...
