Switching from Tropic Marin Pro Reef to Reef Crystals, what to look for?

[KromiX]

Would this transition be ok? All I'm dosing now is 2-Part on a timer, and Mg occasionally for correction....


Anything ReefCrystals is missing Im getting from Tropic Marin? Thinking of switching because of price, anything I'm over looking?

Also, what is the New formula of Reef Crystals @ 1.026 ? I find different numbers because it seems they change their formula all the time... (bad thing?)

AquariumWaterTesting.com did an analysis of 14 brands of synthetic sea water mixes (12/07 - 02/08) which I believe was posted here around 8-9 months ago. The mixes tested were submitted by Reef Central members both ReefCrystals and Tropic Marin were included in this test. The results regarding these two brands of salt mixes are as follows:

I had found that but according to what I read they have changed the formula since then?

I did hear that Reef Crystals changed their formula somewhat. Not sure about Tropic Marin.

I just got a bad batch of Reef Crystals. Fresh mixed to a SG of 1.023 the Mg is only 950-1000 using an Elos test kit. I'm tired of RC and will find a new salt. I don'd mind dosing Ca and ALK, but with Mg levels that low... Plus RC has organics in it that your tank doesn't need. IMO Instant Ocean is better than RC.

I'm trying some Oceanic right now and researching other salts.
