When To Add Clean-Up Crew?

[123justin]

I'm planning on cycling my 20g tank with 10lbs of live rock and plain aragonite sand.

When should I add my clean-up crew?

add your clean up crew when your cycle is done....which means your ammonia/nitrites are zero..

Thanx for the prompt reply.

Sounds like an inadequate amount of LR. Minimum recs are 1- 1 1/2 lbs per gallon. With half the amount, you may have trouble with filtration and nitrate processing. SH
