I'm just beginning to learn how to maintain my pool. I have a stupid question about how to use the in-line pentair rainbow 320 chlorine feeder. I've followed the instructions: closed the control valve, then stopped the pump, waited, then restarted the pump, then opened the lid. The tube was mostly empty, but there was a small amount of water on the bottom of the tube.
So am I really supposed to drop in the tablets into that water? I've read the chlorine tablet warnings, and they are absolutely clear about one thing: I should never add small amounts of water to the tablets: might react violently, etc. But that is exactly what will happen when I drop the tablet in: the tablet will arrive in a small amount of water.
Moreover, even if I get inventive, and open the lid when the pump is not running, to let all the water drain out of the tube, only then insert the tablets and close the lid, I still have the same problem: when I start the pump and reopen the control valve, a very small stream of water will enter the stack of tablets. I'd say that counts as "small amount of water".
So what's the solution? Am I missing something, or am I just too cautious in obeying the choline tablet warnings?
