Looking to bump up my CYA a little bit. Where I live (Southern California) and where the pool is located (outdoors, little or no shade) the pool gets intense sunshine all day long (at least on sunny days---which we have lots of!!). I tested my CYA for the first time this morning using my new TF-100 kit. My previous kit (a Poolmaster 5-way Test Kit) did not test for CYA so I was relying on my AquaCheck 4in1 strips and the local pool store (Leslie's) testing. My first test shows it at about 35 ppm, which corresponds roughly to what I've been getting on the Leslie's tests. My strips showed it being higher, maybe 60-70, though it is subjective.
With all of the intense sunshine I'd like to keep the CYA at 45-50 ppm. I recently stopped using the tri-chlor "hockey pucks", so now if I want to increase CYA I've got to find another means. Does anyone have any suggestions as to types and or brands to use? Or should I just buy whatever seems to be cheapest at the big box stores? In my readings it seems like using a solid product versus liquid is the preferred (cheapest?) way to go. My apologies if this topic has been already covered in the Forums. If it has, maybe someone can direct me to where to find it? Thanks.
