ok I have been reading that Tropic Marin Pro Salt has had some issues with keeping their dkh consistant . I use Reef Crystals have been for years and want to try some of the higher priced salts but need to know if they are worth the extra money? what do you use and why? what numbers do you get when you test your salt batches for water changes? like :
8.0-8.5 dKH, 440 ca, and 1350 mag?
Thanks for the help in advance.
