Finished cycling with LR, now what?

I just finished cycling my 150 gal FOWLR with 150 lb LR. I just put a new fish in QT, so it will be 4-6 weeks before I put anything in the DT. Do I need to do anything to keep the cycle going until I stock the DT (slowly) with fish? Thanks.
 
Not really.... should be fine.... so long as you go slowly. You be surprised how much ammonia is actually still being produced by your rock.

People often fall into the misconception that once they have zero ammonia / nitrite that all the die of is 100% complete. In reality, what it means is that the system has reached a stage where the amount of waste has been reduced and the level of nitrifying bacteria has increased to levels where they are in balance - so, your LR is still producing ammonia, its just that the bacteria are now strong enough to deal with it - so your kit reads zero...... :D

To that end - your cycled tank will be fine for quite a while, so long as you introcude fish slowly, as your say.

Do you intend having a clean up crew of any sort? If so, now is the time to introduce them.

Something about q-tine that people often don't realise. The main thing we q-tine against is ich. If you take a look at the life cycle of ich you will see that it spends teh majority of its time festering on the substrate, until it erupts sending millions of free swimming cycts into the water. If you purchase clean up crews, corals, macro algae, LR, etc. from a source that keeps fish in with the inverts / corals / rock, then it is just as liely you will introduce ich on those items as it is on new fish.

Hence, to that end, if you plan on having a clean up crew, corals or macro algae (or anything else "wet") in your system, then it is a good idea to get them in now - so they can "q-tine" in your fish free display tank...... whilst at the same time you are q-tining your fish in the q-tine tank.

Thank you. Tell me if I should have a CUC. In the 90 gal FOWLR I bought a pack, introduced it into my tank, and 2 days later I had an outbreak of ich. I am suspicious that the CUC is what introduced the ich, so I was reluctant to get another crew for my 150 DT. I will be getting a fish today and will QT it for 4-6 weeks, so if you suggest I do get a CUC, I can get one now, leave the DT fishless for 4-6 weeks, and then presumably I shouldn't have a problem. I just put 5 turbo snails from the previously infected 90 gal into the DT, knowing that it would be 4 weeks till I put a fish into it.

I plan to have a naso tang, porc puffer, greenbird wrasse, maybe a yellow corus (if I could have the 2 wrasses), large angel, and bluechin trigger. I have a 2-3 inch sand bed in the DT and 150 lb LR. If you suggest I get a CUC I will buy one know.

I know reefers suggest turbo snails, nassarith (?sp), and cerith snails. Any suggestions? Thank you very much (and if you need any medical advice, feel free to ask me).
