Opinion on my pool chemical maintenance

[Watermom]

You are right that your CYA may be higher than 100. 100 is the upper limit on the test range so it might mean 100 or it might be any number higher than 100.

Janet (Aylad) does purposely run a HiC2 (high chlorine, high CYA) pool for the very reason you state. Living where it is super hot, allows her to not have to add chlorine every day. Whether this is for the reason you are hoping or not, this is what you are going to have to do by necessity due to your extremely high CYA. Covering your pool will also help the chlorine last longer between doses because it will cut down on loss to the sun.

The question is whether or not to continue to use the trichlor tabs. How many tabs do you have left and are they wrapped or unwrapped? If they are wrapped, I would probably not use any more now but save them for maybe next season. If they are unwrapped, that presents a whole other issue. Read this to see some of the discussion that we have been having recently about storing chemicals:> http://www.poolforum.com/pf2/showthr...-and-chemicals

One caution --- you need to be really careful that you do not get algae. In a HiC2 pool, cleaning up an algae bloom takes extremely high chlorine levels. http://pool9.net/cl-cya/

The tab disposal is ok if I decide that, worst case I would just give them to a friend who has no interest in BBB and I would just give them to her. I hate to lose the $ but I would not charge her for them.

Do you know if there is some rough calculation of how much CYA breaks chlorine down at a certain level. For example, if I keep my CYA at 100, how long would it take for 10ppm of chlorine to get to 5ppm assuming my typical conditions (weather in mid-upper 90s, full sun all day, occassional swimming, no rain). I've tried to google for it but I am apparently using the wrong terminology to search for it.

Unfortunately the tabs are unwrapped, so if I continue to use them, the CYA will continue to creep up, then I fear I will be stuck with an overstablized pool and get myself in a bind.

There is no way to know how fast chlorine will drop to a certain level as there are way to many variables to account for. You pretty much just have to learn what is normal behavior for your pool.
