Adding Live Ocean Rock to Established Aquarium

[Tom Boyle]

Hi all!

I have an established aquarium with 4 small fish (a lionfish, a trigger, a grouper and a banana eel). The eel was a late addition, and I was looking to create more spots for him to hide. I had bought gulf live rock back in March and used that for my initial cycle. My question is if I buy another 20 lbs of ocean live rock (currently have 35 in aquarium), would that re start the cycle? I don’t want to mess with the fish as they are all doing great. Thank you!!

If you do the water shipped Rock from Tampa Bay, then no cycle, death or issues other than possible adding pests.

Depends on how much die off and how quickly the rock gets to you.

I ordered 35 lbs from them and it got to me in 2 days. I gave it a quick smell test, brushed loose stuff off and put it in my tank. This is a 270 gal system though…but I never had an ammonia spike and everything was fine.

If you do a decent amount, airport pickup will ensure no die off.
