? re: cycle in new tank

I currently have a 35 gal tank up and going for 7 1/2 years. I purchased a 30 gal cube 24x24x12 about 5 months ago. I bought a 35 lb piece of fully cured lived rock with the tank and started "cooking" it after I got it home. I finally set up the new tank about 4 weeks ago using the new liverock I purchased. 2 inch sand bed . I have a sump custom made by Barrett. The tank was drilled with overflow. I have LED lights over the tank. A Coralife super skimmer, titanium heater and return pump in the sump. A koralia powerhead on the tank. I have chaeo in the fuge portion of the sump as well as a piece of foam. I only have hermit crabs in the tank, which I put in a couple of weeks ago. I have not noticed an algae bloom. I checked my parameters this am. SG 1.025 Ph 8.4, ammonia 0 nitrites 0 and nitrates 0. Should I expect a bloom? It is safe for me to go ahead and move my 2 clown, my blue spotted watchman goby, peppermint shrimp, Carribean pistol shrimp and my corals over to the new tank? I went ahead and did a 5 gallon water change after checking the parameters, since I had not done one since the tank had been set up. I am anxious to get everything moved over so I can get rid of the old tank. Thanks for your help. This feeble old mind can not remember the process from when I sat up my initial tank 7 1/2 years ago. LOL
 
I would hold off a little while, pretty sure there will be an ammonia spike even if it is a tiny one...I set up a tank once using cured live rock from another tank, even filled it half with water from anoher tank and half new mixed water and tested everything after about 5 days, readings were spot on so i went ahead and added livestock. about a month later i was getting algae of all sorts growing, battled it for about 6 months before i had it somewhat under control, took almost a year for that tank to start looking nice though. Never lost any livestock in it so i dont think ammonia was an issue, but there was definitely a long battle with all the algae. In my opinion i would wait a while for the cycle to complete, wait a week and test everything and see whats happening.
 
I would add one fish and see what it looks like in a week or two...My .02 but beware, i have been accused of putting fish in ammonia chambers!
 
you may not have a cycle i have in the past set up smaller systems with cured live rock and had very little if any cycle it all depends on how much die off , there must be some ammonia present in the system to start a cycle. a small piece of table shrimp or a nice squirt of frozen food will get it started.
 
I personally dont believe in algae blooms or spikes when aquarium is set up right. And soounds like you have!
