Looks like my pool cleaning robot power supply failed. No lights or response from control panel. Tried multiple outlets just in case :) What has been the experience with others on this product? Any realistic expectation on lifespan? This unit is only 2 years old. ~$250 to replace it, can't...

You may have been a victim of the same problem I've been dealing with the past week. The SWG stopped while we were out of town, and upon return the pool was a light green haze with FC at 0...along with the CYA! CYA was last measured around 40 before we left town. It has taken an immense...

I'm a victim to the CYA disappearance after FC went to zero when the SWG stopped while out of town. Last known CYA was around 40. Given the warm temperatures and sunny days, I'm limited to SLAMming in the evening/overnight so not to lose FC to sunlight given the high SLAM FC levels. After...

I discussed this with him, and it will be fixed next season with a timer or variable speed pump and proper SWG setting.

A neighbor who had been getting help from "the local pool store" was saying they were having problems with the pool chemistry. I took my Taylor FAS-DPD test kit over yesterday and measured what I could, but given the high free chlorine levels, or something else going on, would like to run the...

Thanks for all of your replies. Educational and helpful. For the geek in me, is there a post (or an external link) that goes through the chemistry of the FC/CC DPD tests and reagents? One other question I have wondered is the impact on the CC results if you add an extra drop of R-0871 at...

Thanks, Marty. Not sure how I screwed up the daily SWCG generation, but I do get the 1.4 ppm you mention now when I ran the calc again. I'll switch over to the 10ml test going forward. I assume one dipper of powder is all that will be required for that, correct?

I've read that the exact amount of R-0870 powder isn't critical so long as the color changes. Given the apparent instability of my daily Cl readings, compared to what I was expected when computing daily SWG generation from its duty cycle, I decided to run a little experiment. I ran three...

Looks like one white bulb would fit. Thank you.

I'm not having luck confirming if there are any 120V LED bulb options for replacing our existing 500W 120V Philips bulb. Any assistance would be appreciated. Color would be nice, but would be ok with white. Thanks! John

CH 260. Not sure I follow why it would rise with an overall constant volume (and should drop with rain and backwash/drain).

After opening the pool a bit early this year, it has been settling in to good balance and clarity as I have taken over the routine maintenance after the pool service did the opening last week. I will be adjusting levels over time to hit the TFP recommended levels for plaster/SWG. Logs...

Hello everyone! I've been lurking for the past week since I took over our pool maintenance after opening early this year to help provide distraction and entertainment while grounded here with the COVID-19 situation. I've always wanted to manage or pool maintenance, but have been too busy in...
