Mixing salt water is a fairly easy task, but like anything else, there is always tips and tricks of the trade. I'd like to include some additional calcium to my mix. Any tips? Also I know that most of the trace elements are replenished with water changes, but do you guys dose anything else with your initial salt mix to get a better spread of trace elements? On a side note I am mixing in 5 gal buckets at a time and use Reef Crystals salt mix. Any specifics with the amounts to dose will help also.... Thanks.
