Are pucks frowned upon? He would normally fill up 2 floaters with 4-5 3" pucks each. He would also throw in some type of liquid during his servicing as well.Be aware you say the pool guy used pucks. It would be important to test all levels and post them back here when you get them. Your CYA may be high and can be difficult to manage pool like that but only your testing is what we go with.
Was planning on getting a box of pucks to continue what he's been doing... but if he's being doing it wrong I would definitely want to know. The water has always been crystal clear and haven't had any issues swimming in it either.
