If your Aquapure only has 10% and 20% settings that may be part of your problem in managing a 5100 gallon pool with a 40k gallon sized cell. 20% is probably about right in the summer when you lose a lot of FC to the sun but too much in the winter when days are shorter and the sun is not as strong.Also my SWG is usually left on 10% and is run 8 hours a day. Chlorine got low so we turned it up to 20% last week and it shot up to 8 so it is off at the moment.
Why are you running your pump for 8 hours a day? That's probably far more than necessary considering that your pool is enclosed in a birdcage and your FC rises too much.
I'd suggest you drop your pump run time to 4 hours a day and see how that does. You can tweak FC by either pump run time or percentage on the cell. Its a balancing act.
With his fancy test machine....did *he* say your CH was too high? What advice did *he* give you??My friend came by and tested my pool. He has a system called waterlink spintouch which he said is a $700 machine (he used to sell them) and is very accurate. It did yield some different results from what the pool store gave me which does make me question them. I will say after I added another cup of acid this morning and tested it, it finally started looking in the normal range and he confirmed that for me. Results are:
FCL- .56 (I already turned the SWG back on to 5%
Pho-272 (We are going to add phosphate remover)
I added one more cup of acid to stay ahead of the game so it seems I am finally getting somewhere with the ph thank god. Is my calcium level too high? Anything else I need to do based on those results?
I find 30 minutes is sufficient time for MA to mix and show the change in pH. Some other chemicals take longer.I wouldn’t retest it so soon. These chemicals you add need time to mix in and disperse before you can retest them. If your dumping acid in and retest the water 10 mins later your not doing any good. Nothing beats a good Taylor test kit either
True'dat.... letting the water mix up is imperative.I wouldn’t retest it so soon. These chemicals you add need time to mix in and disperse before you can retest them. If your dumping acid in and retest the water 10 mins later your not doing any good. Nothing beats a good Taylor test kit either
