Red Sea Salt

[Invigor]

We use it at petcetera, i don't mind it at all. I used it at home for a while too, then bought a pail of IO (from canadian marine aquarium supply at a supremely great price) and started using it. I started off with a 12g water change in my 70g with IO and like a bang coraline algae started growing like mad.

I'm not sure if it was just timing..the tank was about 8 months in from the beginning.

As for mixing red sea -- haven't had any issues.
