Moving to a bigger tank.

Amiaki · 01/02/2016, 09:07 PM

I'm planning on moving from 37 gallon tank without sump, but with hob filter and skimmer. To a 46 gallon tank with 20 gallon sump. I have 30+ pounds of cured live rock in my 37 gallon tank. For a new tank I ordered 50 pounds of reef saver rock from brs. And I wondring do I need to cycle that rock if I will use same water from my old tank +10-20 gallons of new and 30+ pounds of cured live rock from my current setup

Currently I have 2 clownfish and gsp.

It is by far safest to first cycle the new rock either in the new tank or a separate container like a Brute trash can. If you use all the rock from your old tank theoretically you should not have a cycle but to be completely safe I would error on the side of caution and cycle the new rock first.

U should cycle the new rock because if you add the new rock in the ur system needs to readjust because there would be competition for ammonia/nitrate source. Also I do agree thegrun that introducing live rock is a hit or miss problem as live rock could contain lot of pest and some of those pest are highly .

I'm personally unfamiliar with the BRS rock. Assuming it needs no 'curing' I see nothing to be gained by cycling it externally. It'll become bacterially active perfectly well in the new tank. Just don't add a ton of new animals to the tank all at once .... though, frankly, that's standard advice for even a mature tank.

On BRS web site it said

Quote:

BRS Reef Saver Live Rock is one of the most unique rocks that is available on the market today. Reef Saver is not taken directly from the ocean, and does not impact living coral reef structures in any form. It is always 100% free of nuisance algae or any type of pests.

BRS Reef Saver rock is one of the easiest rocks to work with when aquascaping new tanks or adding more rock to an established tank.

BRS recommends curing all rock before being used in an established system

I don't think it will have any live on it
