Cal-Boost from Canadian Tire

If you look at the MSDS sheet again it shows 60-100% so reads like there is something else in there

[lastlight]

There are no additional ingredients present which, within the current knowledge of the supplier and in the concentrations applicable, are classified as hazardous to health or the environment and hence require reporting in this section.

Doesn't exactly tell you what other impurities are there or their concentrations. Typically the stuff people use is of a certain grade / purity.

No harm in giving the manufacturer a contact and see what they say.

Look into Dow Flake, it's 99% calcium chloride and many people have used it in their reef. You can get a huge 20kg bag for like $20.

^^^ +1, with a MSDS indicating between 60-100% purity you just can't be sure of what impurities you will be adding to your tank. No point saving $15 on bulk additives when you could possibly kill $1000's of dollars worth of coral.

Wasn't there issues with Dow at one point? Levels of borate or something? Does RHF currently support the use of Dow Flake?

I don't know much about it these days but worth looking into I think.
