Algae bloom in new tank.

[gspgretchen]

I have an algae bloom in a tank that has been up for 2 weeks. The base rock is from my prior reef tank and I added some new live rock. My question is can I add snails, crabs, ect while it is cycling? I think there is excess nutrient from my old base rock which was once live rock.

Just check your ammonia & nitrites.....not a good idea to add a cleanup crew before they are both zero.

If ammonia and nitrites are zero - add some astrea snail. They did a heck of a job cleaning up my 450 after it cycled. I would stay away from crabs, they may end up eating your snails (IMO).
