I too am looking for a 'bot type pool cleaner. I currently have a Letro Legend, and was looking at the dolphin. I'd be interested in hearing other folks experiences too...'cause that's a fair bit of cash to throw down for a cleaner! Michael

Ok, *but* my pool seems to be happier at a lower pH. *shrug* Although it could be that I'm imagining things, haha. I do have a paper that outlines killtimes with cya at varying pH levels, and there is a difference. I haven't looked at it in a long time, but I'll see if I can find it and put...

Not really my equation. ;) I'm not smart enough to figure out the balances, hehe. I just found it on the net, but apparently wasn't getting the whole story. Your explanation does make perfect sense tho. Which would be great if PF worked, but it hasn't been up (surprise!) since I joined the...

Jandy valves are usually the culprit. The way I track down air leaks (and if you don't have a SWC, it is indeed on the suction side of the pump) is to use a length of PVC pipe, 1/2" works well. Use it like a stethoscope. Hold one end to your ear, and then trace out the plumbing with the other...

Ok. I like to keep my pH lower than that, usually 7.2 - 7.4. Higher pH reduces the effectiveness of chlorine, since it is more hypochlorite, rather than the hypochlorous acid that really does the work. Be careul with the constant usage of that solar cover. Offgassing is a good and necessary...

Hm. I thought the reaction was this: 2NaCl + 2H2O ==> Cl2 +2NaOH + H2 Now I'm not going to pretend that I wrote that! :wink: I had done some electrochemistry research around the time I purchased my SWC, and to me, the above made sense. Also, in the engineering company I work for, I've...

This kinda puzzles me, mainly because with a SWC, if you use it, it produces a small amount of NaOH. The only way to reduce your acid demand over the long term is to either dial your SWC down, or run it less....neither of which is an acceptable solution. I have a 20,000g pool and I use about...

Yup, that's me. Glad to see it's helpful for ya! It's written in visual basic. Michael

Yup. That's because combined chlorine won't show up in a free chlorine test. More than likely if you don't have any FC, you have some CC. Michael

We are virtually neighbors, heh. I live in Katy and work in Sugar Land. :)

Same here, Dave. I got tired of the same things. This is definitely going to be my new home. I'm out of town for the next few months (in Madrid, Spain) so my posting maybe somewhat sparse, but I'll try to be more active regardless. Michael

Brining! Heck yes! This is one I've used very successfully on pork. Give it a shot! Michael

Here ya go folks, it's the unstoppable BleachCalc! As always, any comments or suggestions are appreciated, and more than likely will be incorporated. Michael Download Bleach Calc 262

Just wanted to let you guys that I'm still around. :D I also have significant experience in running/admining a phpBB forum, so if you need any help, have any questions on setup, feel free to drop me a line. Heck, I may even resurect good ol' BleachCalc! Michael
