a couple calcium questions

[CarlD]

Hunt around. LC is going for as low as $13/5 gallons for 12.5% That's like $1.30/gallon of 6%--a VERY low price.

Cal hypo CAN cause milky water. You can't really use the easy cure of adding some muriatic acid because your pH is 7.2. You COULD raise your pH to 7.8 with, or better, with aeration, then lower it with muriatic acid to clear the hazing. I don't know if that would work, but if the hazing is due to calcium, it might.

Thanks for the reply. Whats the best aeration for quickest ph rise? I normally use sodium bisulfate if I have to reduce ph, is muriatic acid better?

Aeration is simply that: A fountain, a sprayer, a gang of splashing 12 year old boys. It raises pH.

To reduce, in this case, use muriatic acid.

I'm not really interested in the pH--I'm looking to dose milky water with muriatic acid as it can clear it really quickly--I don't think the dry acid is as effective. But your pH needs to go up first before you can try the acid trick. You could use 20 Mule Team Borax--it's faster than aeration.

Then, use the muriatic acid to lower pH again it should clear the milky water. This, of course, assumes that excess calcium is your problem.
