Thanks sounds like a plan. The next step in all this is to add my LS and my Refugium. Then later down the road, due to finances add the LR. Here is the question, If I do it in steps like I mentioned will the tank start to cycle with the addition of the sand ? My guess is yes. So say it cycles before adding the rock what would happen when I add the un-cured rock to the cycled tank ?? At my LFS when the LR arrives there is no time to cure because it sells so fast !!!! Maybe I should cycle it myself in some other type of container or tub ?? Thanks again.
