Cycling with Gulf Live Rock

The nitrite is not toxic. I’d stop measuring it and ignore it. It will go away in its own time, but there’s definitely no need to add anything to speed that along.
Hi Randy!

So at this point, would you consider adding a fish if the ammonia is at 0? The nitrite/nitrate levels are irrelevant?
 
Just use the rock and water changes. I have 40 lbs of gulf live rock that i have gotten in the last month or so. I setup a 20 gallon to keep it in with a heater, two koralias, a cheap led light, and two fish so something is being fed and keeping nutrients going. There wasnt a lot of die off, but definitely some. The rock is beautiful. The water had a slight smell for the first few days. I did 50% water changes for the first few days, then 25% for a few more days, now i do a 25% every few days, and the rock is completely usable(probably is anyway after just a few water changes, and a visual inspection/smell test). I have added a few chunks of it to my 3 month old reef which i started with all dry rock. I pulled out some of the dry and replaced it with the gulf rock. Heres my 30 or so lbs of it, minus what i grabbed and put into my reef. This is my first time getting genuine live rock. Its night and day compared to dry rock. Its loaded with purple and red coralline. I was nervous to get real live rock due to pests, but The hitch hikers havent been bad that i have noticed. I caught a few crabs and isolated them, but they may have been harmless anyway. I caught one welk snail, and have nuked a few aiptasias. I read a lot on here first, and agree with the general concensus, the pros far outweigh any cons with liverock

Is this the premium or base live rock??
I'm So torn on what to do on a new build with rock in general.
Setting up a 130gal display.. What is fishing out hitch hikers like in a larger tank?
Harder but not impossible I guess.
I think you went the right direction for bringing LR into an established tank -> Clean it up before the addition to display.

I got the premium. I suppose the very best option would be to get the LR, put it into its own tank for a week or so, and observe it for pests, and remove things as you see fit. This is the route i took. I havent observed any issues with the liverock.
 
I have used both premium and base LR. After about 3-4 months, I can’t tell which rock is which anymore. You do introduce a heck of a lot more stuff (good and pest) with the premium.

Curious if there was a delay in shipping or getting the rock in the tank.

You spend the big bucks on real ocean live rock for a lot of reasons, but one of them is an almost instant cycle w/o products.

Get the live rock. 1lb per gallon.
Minimum would be 1/2 premium and the other half dead. I did this on my old 120 with excellent results.

Hitch hikers can be difficult to remove. I have a Mantis shrimp in my 150 and 50. Currently using a Mantis trap but I have caught many snails and crabs, lol. They are not the easiest to remove.
Fish are easier to catch. Mine have been in both systems for a year now and they will kill all your crabs and some snails. They will attack fish too if given the chance.

S nafter 30+ I would still choose Live Rock every time.
My current 15g nano was started with 20lbs of live rock from the lfs. It was from a tank breakdown and is another way to get good rock when someone breaks down a system.

The last one I caught, which remained elusive for months, was with a bottle trap that I put mysis and krill in, and I poked a ton of holes in the bottle trap.

I have one left I believe, and will likely go this route tonight.
 
I reluctantly used this rock on a quick build. It cycled immediately. Never had any ill effects from hitchhikers.
 
Hi All!

Quick question regarding cycling with ocean live rock. I recently purchased 35 lbs of live ocean rock from Gulf Live Rock and put it in my new SR80. I’m sure there was some die off on the rock, however a lot of the larger hitchhikers survived (clams/mussels/tunicates). I did also add Fritz TurboStart 900, as my lfs suggested it. When I initially tested the water, the ammonia/nitrite were spiked (see attached). Six days later, it looked like ammonia looks much better, but the nitrite and nitrate are spiked. I know this is all part of a cycle, but shouldn’t the live ocean rock and turbostart eliminate a full cycle? Do I still need to wait until the nitrite/nitrate gets to 0 before adding any fish?

Thank you!!

No - if stuff from the live ocean rock are 'dead' or die shortly afterwards - your ammonia can spick - However - as you can see the bacteria rapidly (and its probably heterotrophic bacteria mostly) - can rapidly reduce it. To me your ammonia reads 0, your nitrite is a little high - but it shouldn't cause a problem and will likely drop quickly, and your nigreat is at the level just above 0 - which is also fine. It's a bit hard to tell due to photography and lighting.
 
Would there be any clean up crew that could help with any of the die off from the live rock? Nassarius snails maybe? Everytime I’ve used Fritz 900, it’s pretty much an instant cycle so I’m assuming the live gulf rock is the outlier here
I would add the Fritz - though it will cycle fine without it - this will speed things up - and hopefully will lessen the need for water changes, etc - though - you will likely need one. And you're correct IMHO - it is kind of a chain reaction - one thing dies, then another then ammonia then more, etc etc. To make this more clear - what I mean is that dead thing decomposing can affect the living things that would not die. So In this case I disagree with Randy - though - he's correct with nothing - things will still move forward - but if your goal was to have living things from the ocean - adding bacteria may halt some ammonia production from anything else that is dying.
