I've always used RC and been happy with it. My Cal. is around 440 and my alk. is 8 in a mostly sps 45 cube.

So the 31 people that viewed this in the sps forum don't have an opinion on what salt they use. Maybe u don't use salt? Why no responses from 31 viewers![]()
This is also what I use. Doesn't seem all that popular!
Probably because this question has been asked over and over.
I have used Instant Ocean, Reef Crystals, Seachem Reef, Seachem Marine, Coralife, H2 Ocean, Tropic Marin, Tropic Marin Pro, Red Sea Coral Pro, Brightwell, Tunze, Marine Environment, BIO-SEA, and natural sea water.
Those are just the ones I can think of right now.
Honestly could not tell much of a difference with any one of them. Nothing worth worrying about anyway.
So your newly mixed up saltwater, of whatever brand you are using today has a slightly higher or lower Alk or Ca level than your DT.
So what?
How much is that really going to change the levels in your DT by doing a 10% water change?
Unless you are doing a 50% to 100% water change does it really matter?
So if for example you have a 100 gallon system and your Alk is at 8.
You do a 10% waterchange with some kind of crazy high Alk salt mix. Let's say its 14.
How much is your DT Alk level going to go up to, from this 10% change?
8.2 ?
8.5 ?
I know one you chemistry guys will chime in with the correct answer.
