Buying calcium -- this is ridiculous

[aylad]

Why not just chlorinate with Cal-hypo for a little while? It won't take the calcium long to get where you need it to be...

That was what I was going to suggest, but Jan did it first.

Cal-Hypo is usually available all over, as either HtH or the other brand I have a mental block against. If you can get the 62 or 68%, it is better than the 48%--less impurities. But be careful with it--don't mix it with other chlorine types (once in the water it's OK--if you've been using Tri-Chlor or bleach, just use Cal-Hypo instead).

Most of the cal hypo out there these days is 48% since it's classified as a class II oxidizer and not a class III oxidizer so it's safer to ship and store. A one pound bag will raise the calcium in 10k gal. about 3 ppm. This will be a very slow way to add calcium. Evan if you can find the 68-72% stuff it's only going to raise the calcium in 10k gal. by about 6 ppm per bag.

Thanks waterbear, waste, aylad, and CarlD, for your thoughts. I especially like waste's suggestion about getting a kicker agent from a ready-mix company. We have about a zillion such outfits here. If they can't help, I'll hit the pool store for a 50 lb. bag of Dow or Tetra.

Let's call switching to Cal-Hypo 'Plan B'.

Cal-hypo is actually very easy--you can't easily over-calcify your water if you check the CH level every week. It will go up slowly and steadily. There's nothing WRONG with Cal-Hypo. I don't like it because I use bleach and don't need calcium to rise in my vinyl pool.

I have found Peladow in pellets is this safe to use in my gunite pool, need to raise my calcium about a 100 ppm. What is the safest add best way to add this? I found this at a tire store, they put it in tractor tires!

Thanks

Sorry, I can't help

You want waterbear or chem_geek for this (or possibly Ben and others)

I just wanted you to know that folks are reading this and waiting for the ones who know to answer
