I recently installed a SWG and still have the old Rainbow 320 chlorinator inline. Has anybody ever used the Rainbow for injecting CYA? I tried it out for a few weeks and it seems to work pretty well. I've got it set at the #2 position.
Good point!Aquaman95 said:Perhaps the OP is referring to using trichlor tabs at the opportune moment coupled with BBB to lower pH, increase cl, and add CYA?
Good points!PoolOwnerNumber9 said:You note that this is being used on a SWCG pool. There are two things you need to be careful about. First, if the feeder is in-line after the cell, the hydrogen gas generated by the cell could build up in the feeder and that would be very dangerous. If the feeder is in-line before the cell, the concentrated cyanuric acid would interfere with the cell's performance
