Last July, I came here for help clearing a cloudy pool. With advice from others here, I lowered CYA from around 270 to normal over the course of three rainy months, chose a new pool robot, and have kept the pool in great shape with only one brief SLAM needed after being away. It is so nice to...

I called back to get confirmation that the T55i and S300i are the same robot with the same full featured remote app, just sold in different regions.

I am not an expert on Dolphins, just a homeowner who made a couple of calls to Maytronics. This is what the two agents told me. The first agent (top of the chart) seemed to be consulting both 2017 and 2018 model year information, while the second gave information on 2018 models only. There are...

Years ago, we had a long period of relative drought followed by recovery with lots of rain. After the rain, a small void opened in the intersection closest to our home. The county repaired it many times as each repair would get swallowed up by the hungry void. Just as I was beginning to have a...

I spent too much time trying to solve this problem, and am posting here what worked in hopes of saving someone else some effort and hassle. One of the two knobs that hold the lid on my Hayward strainer basket kept popping out when I tried to tighten it down to reseal the lid after emptying the...

True, it's not much different, but Maytronics says they haven't sold it in years and cautioned that if anyone has one, it would be aged in storage. Still shopping. I find it frustrating that Doheny's refers me to Maytronics to learn about Doheny's branded Dolphins, but Maytronics can't answer...

Thank you! I am very happy with the results! So much nicer than paying for gobs of water! Oh my! Yes, I have raised CH. I enjoyed showing my 12 year old the exothermic reaction. =) The pool needs it again now. CH 230 CYA 40 (no longer intentionally lowering) TA 100 pH 7.5 FC 7 CC 0

This sounds like a great solution, but I'm not sure I understand where the plastic needs to be and where it should be removed. Does this mean apply to the inside of the male piece continuing onto the outside of the piece, and remove from all recesses within that piece, leaving it on the raised...

I may be there with you eventually, ka8yiu. I was happy to read a CYA test of 55 last night. So much progress in just under three months, and with rain water instead of a huge water bill! I'm hoping I can learn to manage CYA with dichlor and trichlor when I get to that point since I have some of...

Hi, Skenn81. I had to raise CH for the first time in a long while recently too, and I had the same question, plus I wondered how volume differs if you buy pellets or flakes. I bought 94% pure anhydrous CaCl pellets. The first time, I measured half as much as the pool calculator said in a...

Currently you can find 50 pounds for $24 with free shipping and no sales tax to Florida on Amazon (4-8 day delivery, not Prime). It was slightly less from another vendor with a slower ship time. The same brand and size was $30 at Tractor Supply. Home Depot and Lowes sites say they won't ship it...

Just wanted to provide an update for any future readers of this thread. During a central Florida summer, when we get lots and lots of rain, and with directing rain water to the pool beyond what would fall on it naturally, it took a month and a half for the estimated CYA to fall from 270ish to...

We've discovered some additional items that were damaged by the same lightning strike and are now looking at an insurance claim that would presumably replace the Dolphin. I am finding Maytronics' site difficult to use. The comparison table it showed me for three current models showed *identical*...
