OMG! no Cal hypo is really basic! but good explanation none the less that while add liquid or cal the pH will rise and then drop back down to the original level once the CL has diminished. And as you say it is an elegant way of saying adding bleach 'is' effectively pH neutral because the pH...

oh ok i was just curious because if someone SLAMS a pool.... say with Cal Hypo because of the nature of Cal being 'basic' the TFT forum say to drop pH to very low 7's because adding the CL will raise the pH automatically with the SLAM sized Cal hypo in the water that part i understand...

while SLAMMING i get that... ill drop it down to 7 or so on the pH... The pool is fine as far as chlarity and all that but... my CL has to remain high because i do have 50 PPM CYA and it is an outdoor pool in Mexico where the sun is near 0 degree straight up quite strong. Back to the point...

From reading the Forum here, you cannot accurately measure pH beyond 10 ppm of CL, that much i understand. In one of the Forums, there are several methods to circumnavigate around the problem. One of them is by diluting the test sample (1:1 ratio) with distilled (only distilled!) water...

1.5 kilowatts = 5,000 btu's more or less . so to raise it 1 degree, could it do it in 6 hours one day and then by the weeks end 30 hours later, 5 degrees and then hold it to that, could it do it without killing it? or is heat evaporation faster than it can generate?

id like to add an electric hot water heater. all i need to do is heat the water 5 or 6 degrees F. i have 7,500 gall pool. or 60,000 BTU's to heat it 1 F. it only gets cold down to 65 F but 85 during the day ... so the water ends up around 70 F mean ave. id like to get it up to 80 F. if i put an...

great ! thank you. i read or i'm still reading the post he left me ( the graphs from his previous post). I guess all that is condensed into the Pool Calculator or Pool Math for you, as it were. BTW, 7 day into the Slamming, water is 95 ~ 97% clear, i'm brushing it 3 ~ 5 times a day to get the...

one last question.. if the cya is around 50 and the FC's are between 5 ~ 7 wouldnt that also give an artificially high pH reading?

reading chem geek's last reply is something i know now thanks. sorry for the mis-information

I thought heat would shorten the life span of chemicals, obviously the sun would be the worst yea. I heard reagents only have a shelf life of a 1 year, so knowing that, i figured storing then in a refrigerator would help prolong the life of them.

testing TA,CH, can it be done during the Slam process or will the high CL interfere with it?

of course! the kit gives you a proper basis or proper starting point and able to monitor the critical phase of Slamming. The kit i had is a not a Taylor test kit but a version of it in a foreign country called Spin. the company attempts to mimic the exriact look of the taylor kit. I tested the...

last year, i didn't have a FAS DPD test kit like the TF 100 mentioned. I couldnt tell how much chlorine i had but i knew i had a truck load of caclium Hypo in the pool. ( i wasnt as knowledgeable back then). I couldnt understand why the pool remained cloudy, despite high levels of FC, vacuuming...

for instance, i read somewhere ( i could give you the link) that below 7.5 pH, the Hypochlorite acid is less dominate but the Hypoclorous acid is. The latter is not as effective. At 7.5, both are present and equal in the water. also, wouldn't the pH lower, if more dirt ( bacteria laden dirt)...

well thats just it - is running a pool a strick chem science or a 'Cady Shack' way of running a pool lol ( a chocolate bar in the water looking like ***). i do like the science tho behind what you all mentioned that bleach is neutral. I do like what chem geek has said. I just feel its better to...
