HTH pool Calcium

[240gallons]

Anyone using this at Part #1?

Also, can someone point me to the current recommendations for Randy's 2 part? The recipe is 10 years old and want to make sure there have been no revisions....cant seem to find it

I don't know but I would be afraid that it would have other stuff in it. I wouldn't think they would be concerned about how pure it is.

Here's the original article:

The new Dow Flake is more concentrated, so I think about 20% less is appropriate.

People have been successful with pool products, but the testing to determine safety would be prohibitively expensive.
