Simply my opinion.

I like higher end salt... Like some people think MP40s are better than lower price power heads. Both create a different environment... Pleasing to some and not to others.

I use H2Ocean and love it.

Two more days till Boxing day and still don't know which salts to buy for my 280G reef starting next week.

Its much easier to go with a more expensive salt when you are only running 1 or 2 small tanks and by small I mean under 90gal. I have at this point close to 450 gals of water in 3 tanks so its Crystals all the way.

If you can afford to go with a more high end salt then I would go that route, I know I would. Roughly figure out how much you would use in a year and ask yourself if you can afford it, not at boxing days prices but at regular price.

OK let camp out at Big Al's.......Just kidding
