Brightwell reef code A-P confusing mixing instructions

[donnellb]

I noticed that on the 1000 gram container of Reef Code A-P (Calcium Powder) it states ((Create a stock solution by dissolving 70 grams of Reef Code A-P in 8-fl. oz. of purified freshwater.))

But on their website for it states: ((Create a stock solution by dissolving 35 grams of Reef Code A-P in 8-fl. oz. of purified freshwater.))

Brightwell Aquatics - Reef Code A-P

Which is correct the 70 grams listed on the actual container or the 35 grams they have on the site. I'm trying to create a 1-gallon mix for auto dosing into my 75-gallon mixed reef.

I have posted this question to their Facebook page and I tried via the Brightwell site but there seems to be an issue with the form.
Even tried calling and just get voicemail.

Surprising for Brightwell, but both are correct.

Note the one on the bottle is 2x as potent and claims to raise calcium twice as much.

You can use either (or neither).

Thanks for pointing that out. I read the entire set of instructions multiple times and completely ignored that number. Thanks again.

You're welcome.

Happy Reefing.
