Dupont calcium hardness increaser

[matt]

I went to Lowe's the other day to try to find some dowflake; couldn't find it and instead found this product in the pool care section. The label says 94% calcium chloride, 6% inert ingredients. Think it's reef safe? The 6% could be moisture, or some additive that makes it unacceptable for a reef tank. Anyone have an idea about this, or, where can I get dowflake here in San Antonio?

Id be real careful about what 'they' consider inert to particular applications. Give them a call and see if they even know what the remaining 6% consists of. Personaly, I wouldnt use it until I was positive it was safe. You can order Dow flake from Buckeyefieldsupply if you cant find it localy. Or I can send you a pound or so since I have more than Ill probably ever use.

Matt, you should be able to get a Material Safety Data Sheet at their website. That's what I did with the Dowflake. Its probably the same thing. Sounds similar. The inert is probably moisture content.

I'll check it out and get back to you.

Inert ingredients are.... drum roll please.

Sodium Chloride (Table Salt) and Potassium Chloride (Lite Salt).

Here you go.

Okay, great, thanks Gary. I was looking for something like that but couldn't find it.

Hmmm, should I ditch the group order?
