just started AWC

[Devaji]

Unless it is one of the few salt mixes with organics in it like reef crystals, salt mixes can sit unstirred just fine. In that case, it may need aeration to prevent reduced O2 from bacterial consumption of vitamins.

Mixing does not reduce precipitation. If anything, the heat of mixing can accelerate it.

Randy, If I am reading this correct IO reef crystals need to mixed in the AWC container. are we talking a few days a day or 24/7.
I will be setting of a AWC system on the new tank after the move. and I use reef crystals. just want to make sure I do it right

Reef Crystals has the potential for bacterial growth and to become anaerobic. I do not know for sure if that is ever or sometimes or never a true problem. Normal IO and most other mixes do not have any such possible problem.

thanks good to know. I add a power hear on a timer. any thought on the amount of daily mixing it should have?

Not sure, but 15 minutes might be enough to bring in sufficient O2 since the amount of organic matter is quite low.
