alright a question i want to get out of the way.

So the rock i have in the tank now that is just cycling away is dry rock that came out of Mikes tank.

about 40lbs, im doing a minimalist look.

Im going to do two islands one on the right and one on the left. I have 2 tanks that are going to be taken down and put into the 90g

All said ill have about another 40-50lbs or more of LR to put in that tank.

WHen i take down the tanks will the Live rock that i've had in my tanks for 7+ months be able to handle a fish or two when i do the switch over?

I know the Dry Rock that is cycling wont be fully cycled but will the LR i have now take on the burden of the added fish? Its going to be two firefish and likely a single occy clown.
