I opened my pool a couple of weeks ago and filled my Hayward CL200 chlorinator with 3'' tablets. I usually set the dial on 2 with good results. After over a week, the chlorine level was nill in the pool....
A CL200 Involves direct injection of chlorine into the pool. Water passes through the chlorinator and goes to the pool with chlorinated. WIth the 200 (Not the 220) I've only seen a handful with problems over the years with chlorine not dissolving. If the chlorinator is not leaking, and the control valve is moving freely here's what I'd recommend.
1. Are you using a new type of tablet?
If so remove the tablets and place into a floating chlorinator.*** WARNING Wear Rubber Gloves, while handling wet tabs****
Dial it all the way open. If the tablets don't break down at this point with in a day or two, They were over compressed at the factory, potentially have to much filler (most slow tablets should be 95-99% cholroine) or the water is too cold ( below 70 deg. This should not be an issue in July) If this is the case switch brands.
If the chlorine is dissolving in the floater but not the chlorinator it could be one of the following.
1. Make sure the direction on the chlorinator is correct inlet (from Filter) to outlet (to pool)
2.. In some of the newer 200 chlorinators there is a built in check valve you can see it in the bottom of the chlorinator You will notice a threaded piece in the bottom that contains a white plastic ball the size of a pea. If this ball does not move freely to the touch, odds are the filler in your chlorine has clogged it from moving, thus preventing the flow of water from dissolving the chlorine.
You can check this by removing the chlorinator from the pool, removing the lid and pouring water directly into the top. If you do not see water passing through to the "Outlet" side of the chlorinator a clog is most likey your problem.
I've seen clogs cleared with wire coat hangers and hot water. Be forewarned that hot water being poured into a chlorinator will cause the any residual chlorine to gas off, make sure you do not have you face over the chlorinator when you add the hot water and you do so in a very well ventilated area. A straightened wire coat hanger can be used to dislodge any obstruction in the check valve and "get the ball rolling again"
Hope it helps.
