    Salt composition

    Pulled this off of RC;

    This thread contains data gathered by member Billybeau1. Thanks!

    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 SG 1.0264 @ 25 C.

    So based on these figures and assuming a full reef setup, is anyone going to change which salt they use?

    I think I have Instant Ocean right now and am thinking a higher Ca would be good.

    Nope, I use what I win in raffles or buy IO or Oceanic.

    Where do you get CoraLife around here anyhow? Do you need to order it?

    We could do our own average readings for the Salinity (maybe if we get enough it could get added to the list), I'll start:

    pH: 8.5
    Alk: 9.8 dKh
    Ca: 433
    Mg: 1338
    SG: 1.026

    I got this info from the "lab certified values" column
    Happy Reefing!

    Fortunately all three params can be adjusted independently without switching salt mixes.
