Just to add.
It is not a good ideal to put pucks in the skimmer basket due to low ph. It may harm pumps and such down stream of the basket.
I would give thought to just using plain bleach as mentioned. If you do use just the plain bleach pour in fron of the return not in the skimmer. You have a puck feeder and the diffrent chlorene sources dont play well with each other.
