    Trichlor feeder options for variable speed pumps?


    I know the issues with Tricolor sanitizers but have been using them without issue for the last 9 years but want to switch over to a feeder vs floater with the new pool heater. Does anyone have any experiences using these with variable speed pumps as I've read some issues exist. Normally during filtration it runs at a lower speed but during the gas heater use and solar panel use it speeds up and I've read that can play havoc with them.

    Any thoughts and experience would be appreciated.

    Why not upgrade to a salt system so you can solve two problems at once?

    I run my VS pump at 1100 rpm to skim, filter and make chlorine with the SWG. It uses 150 watts. At 10.25c/kWh I can run it 24x7 for 12 bucks a month. I run solar at 1950 rpm and it uses 550 watts. Been running like this for 4 years, works great!

    Pretty straightforward math. If you increase your pump speed, you will increase your FC output by about the same percentage. Complicated if you are adding chlorine 3-4 times daily, for sure.

    I had a new water in line which cane with the frog system. My vp pump ran 3800 rpm for 12 hrs a day. Of course this was a single speed so once I got it turned in it was great . Rainy days I would bump it up or down. Quit convenient. I was just unaware of the rising cya.
