How to add CYA?

[waterbear]

There are other options for adding CYA to the pool. There is a quick-dissolving and fairly pH neutral formulation of a CYA salt called "Instant Pool Water Conditioner" made by "Natural Chemistry" and may be seen at this link. I've never used it, but I've been in communication with the chemist who developed it so it's certainly an alternative (it's a sodium salt of CYA in a slurry). Another alternative is to use Dichlor since that is also quick-dissolving. Of course, that also increases FC, but chlorine is something you need to add every day anyway so doing a "shock" with Dichlor is one way to add a lot of CYA relatively quickly. I haven't checked comparative prices for these options.

Richard, Did the chemist tell you why the product is not approved for use in California? (Then again California also does not allow borates in swimming pools so maybe they just are a bit too strict out there!)

Edit: Don't get me wrong. NaturalChemistry makes some excellent products! Their enzyme based products work very well. I have found that their EDTA based metal remover does not prevent stains from returning in a fiberglass pool as well as phosphinic acid based products such as Jack's Magic or Proteam's Metal Magic. Not trying to hijack the thread. Just want more info on the NaturalChemistyr stabliizer!
