I need to buy some salt, maybe I will try a pail of IO Reef Crystals just to see. My water change system is now done so I suspect I will be doing weekly 50G water changes and will be going through a fair bit of salt.

So 1 50G water change on my 200G tank with Instant Ocean salt (not even Reef Crystals) and my corals look bigger and more open than ever before while using Salinity.

Not just a small difference, a huge difference. I don't get it, zero change in tank parameters.

Price:

Salinity - 225G mixed is $160, $100 on sale

Instant Ocean - 200G mixed is $75, $40 on sale.

Not sure where Reef Crystals falls price wise but I believe it is pretty reasonable.

I just bought a bucket of IO Reef Crystals (160gals) from petsmart it was $70.
