Diy calcium chloride (A Little Help)

[Razor Ramon]

I really like the idea of the means to send the water off monthly and they give you a complex break down of the water chemistry.
If a product is bad or you have equipment failing and adding something bad like metal or chemical poising to your tank it can be cought before it builds to a toxic level.
How much dose this service cost for a year and is there many labes that will do this for reefers.
Cool tec for sure !
Not really up on bleach/ hydro peroxide can you post a link if it’s worth a read .
thanks .
I know there is reactors for hydro peroxide to add radical oxygen to the system but not widely used by many in reef settings .

Took the bags back calcium chloride anhidrous there chemist at the chemical supplier had a breef talk with me said it had been contaminated because it acts like a descant ( no moisture) so it absorbs like a sponge . He figured the factory’s steel containers had rust so it absorbed iron oxide .
That is the red mud that I screened out .
So is it safe no one knows
if it’s iron oxide probly ok
but it would been realy bad if it was used if it’s copper sulphate.
They replaced the product and gave me the contaminated stuff for my drive way.
Thanks all for your input.
