Hi Everyone,
This is a bit of a weird one, but wanted to run it by everyone and see what they thought. We have an 18'X40' inground vinyl pool, with an inline chlorinator. We bought the house last fall, and this is our first summer with a pool.
If you see my other threads, we are in Canada, and it is all but impossible to get a decent testing kit for our pool (To get a basic K-2005 is $285 + taxes + delivery). Up until now, i've been using the basic kit to keep everything in range, and finally broke down and bought test stripes just to make sure something wasn't completely out of whack.
This pool is fairly old, and has always been chlorinated by using trichlor pucks according to the owner. When they closed it last fall, they didn't drain much water if any from it (it was actually mid-way on the skimmer).
Keeping all this in mind, I half expected to get high CYA levels using the strips, but I ended up getting the following:
FC: 1-2 ppm
Alk: Normal (60 I think? Going off my memory, but it landed right inbetween the "normal" range listed on the package)
pH: 7.2
CYA: Somewhere between 0 and 30
So the CYA levels really threw me off, which brings me to my question, just how much CYA do pucks add to a pool? It looks like I need to add some, but i'm worried that I'm going to regret that in a bit since I'll be sticking with pucks for the season (BBB looks good, but we're new pool owners, and are frequently out of town 2-3 days at a time).
Anyone have any figures on how much your CYA raised over the season by using pucks?
Also, anyone have any ideas how despite this pool being run on pucks for about 8 years, it has such a low CYA level?
