Moved from here. I am really hoping for a reply from one of the web’s experts. I am getting this impeller overload alert every time I start my S300i. I have taken the parts off, I have looked at impeller. There is NOTHING impeding its motion. I have noted that it doesnt move without a little...

Many thanks!!!! I went with the 0607 model

I posted this on a Stenner thread. I will try a new “generic” thread. basically my question is: should I choose a flow rate for a back pressure higher than what the pool filter shows? Would it reduce the run time of the dosing pump because the flow rate is higher? I am buying a replacement...

Please forgive me if this has been answered. I am buying a replacement solenoid dosing pump for liquid chlorine injection. From years of experience, I know that I regularly use between 1 liter and 1.25 liters PER DAY to keep my free chlorine level at 2-3ppm which is fine for my pool. My question...

Thanks for your replies. Wheels seem like soft plastic. And I meant to say in my first sentence, "the robot seems to be a great PRODUCT" not problem

Just purchased Dolphin300i and it seems to be a great problem. But I stumbled on the first page of the caddy assembly. I could not get the plastic plate off to use the 2 screws to hold the verticle pole. I did not want to force it and break the plastic. Any suggestions? many thanks (See...

[How in the world did people care for their pools before the age of the internet?] Amen to that. And especially TFP !! I live in Italy and rely on this excellent web site as a professional text book. thanks to all those who give up so much of their time to contribute answers to us newbies and...

Thanks, Richard

thanks, Richard. I was hoping you would see the post and weigh in with your always-welcome advice. Does it make sense to you that preventing outgassing of carbon dioxide might actually REDUCE pH, not just keep it stable? To help stem pH increasing before the blanket, I had been keeping TA...

i recently decided to replace my hot tub cover, and in so doing, came across the idea of using a termal blanket (closed cell polyethelene foam, supposedly clorine resistent - but after receiving it I have to wonder if one needs to pay the premium for this from a spa store ??) My goal was to...
