A General Guide to Salt Mixes
Here is a list of what I measured for the big three in a number of the salt mixes we use today. This is intended as a guideline and I, in no way, guarantee these figures. All I can say is they were all tested under the same conditions, with a number of different brand test kits, using the same methods for each test. I believe these numbers are reasonably what you can expect from these salts mixed at 35 ppt or 1.0264

A special thanks to Bertoni for putting it in nice form.

Makes me wonder, because my last bucket of Reef Crystals was

I tried it because they said it was higher in Ca. Pfffft, that was a lie.

The Seachem Reef Salt is my second choice, and it's a good 20 bucks cheaper per bucket... I may change my mind before I actually send the order in.

Myka, for sure we will have to do that some day... I will need to come down and get some stuff for the contest tank at some point this summer, if summer ever comes :biggrin: On a side note, I think that very few salt mixes take things to NSW levels, but I want to be close(r).

No kidding...it's snowing here right now...oi!

Ha, you are getting what we got yesterday!
