Attaching my spreadsheet. It is similar to many others. If I were smarter and/or had more time I would build a small Access database and form to capture and report on the usage, etc. Heck, with something like that and the Pool Calculator available as iPhone Apps I might have to by an iPhone...

OK, I wouldn't normally wade into the Deep End, but I want to make sure I understand what occurred. I believe this scenario happend with my pool as I had a 30 to 40 PPM of CYA at the end of last season and then very low CYA when I tested it in March and I had not done any backwashing. I...

The best price I can find on bleach is at Costco. They sell a box of 3, 182 oz jugs of 6% Clorox Bleach for $7.99 here in NorCal. Regards.

OK! Off to Wal*Mart I go to get the Borax. Thank you for the input and feedback!! jcichocki, thank you for closing the loop and confirming your success. We are still a few weeks away from swimming here, but that will give me the time to get the borates in and the pool balanced.

I read the sticky about adding the 30 - 50 PPM of Borates, ordered some Borate test strips, and was about to purchase the Borax at Wal*Mart to get it done. I took pause when I read the warnings on the box about being an "eye irritant and "may be harmful if swallowed". Since getting the stuff...

The 380 seems to be getting the job done, but because it uses a booster pump that runs daily with the filter pump I was thinking that a robotic cleaner could just be put in once or twice a week and use far less electricity.

Hi All, Since I can not find robotic pool cleaners in my Consumer Reports magazine I am hoping that I might be able to draw out a few posts on any personal experiences with these devices. I am considering replacing our Polaris 380 with a robotic cleaner. I have two primary factors/assumptions...

The clean filter, with the same open valve settings, is running at 23 PSI. The other return line is for the slide; and yes, the other pump is for 3 sheer descents. So it sounds like our pool should be turning over every 3.2 to 4.0 hours. If I understand correctly, I should easily be able to...

Mark, I really appreciate your patience and assistance! I think you may be correct about the return line; it might by 2.5 to the pool and 1.5 at the pool or perhaps 2.0? I set the skimmer/drain valve so that both suction lines are 100% open. The PSI moved from 25 to 26. Based on your...

Will these images help address your questions? It looks like the lines are combined at the pool before the run to the pad. I have other images, but can only upload 3. I just thought to add there is a valve at the equipment that allows for a flow/suction adjustment between the drain and...

Hi Mark, I have been following the filter manufacturer's cleaning frequency instructions, "The most commonly used but less accurate indicator is to backwash when the filter gauge reading increases 10 PSI over the initial (clean filter) reading." This is because I do not have a flow meter and...

Thank you all for your quick responses. I really enjoy this forum and have learned a lot by reading, and searching, and reading, and searching more... Based upon my reading from this forum and information from my builder I believe my turnover rate is approximately 4 to 5 hours. Here is the...

Hi mas85, I am out here in CA as well, Tracy. I would love to reduce my pump time with the cost of electricity. Is there a turnover rate calculation in Pool School or elsewhere? I have only been running 4 hours a weekday during the off season, but was running 8 hours a day during the summer...
