    Opening pool robot question

    Can I put the robot in and put it on before adding any chemicals? I am assuming yes since it says to keep it below 4 chlorine.

    Yes. It will help mix any chemicals you do add. And the 4 FC is with zero CYA. That's actually way strong, like shock level. If you keep FC below shock level for your CYA, the robot will be fine. Unbuffered chlorine is what's so rough on robots and swimsuits and eyes.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    Predator, what's your water temp? Just so you know, last year I put the robot in service on opening and while it went through the motions, it went Veeeeeeerrrrrry verrrrrrry slowly Apparently its not fond of water in the 40s. Somewhere in the manual, it confirmed this. So don't be alarmed if yours does this -- its not broken, its just protesting
