Tank upgrade question

Mavric · Jul 30, 2018

Moving from a 13.5 gallon to a 20 gallon. I seeded the new tank with the 12ish lbs of live rock and water from the smaller tank as well as added about 6lbs of dry rock and another 8lbs of coralline-covered rock taken from another system. Should the cycle be ok or should I continue seeding bacteria for a little bit to help it out?

In my opinion, youve done what needed to be done and i doubt you'll even see a cycle-peak on NO3 or PO4 if you keep up the same habits/routines

I would use some BioSpira or Dr. Tims but there has to be something nutrient wise in there for it to consume.... What are you giving to produce a cycle?

I had two smaller fish and some CUC inverts. Been testing religiously for spikes with a bottle of prime handy just in case but nothing yet.

u are good to go, may have/experience a mini cycle but should be ok. I did similar thing when upgrading from 65 to 93 cube. U did not need to reuse the old water from smaller tank though as it's essentially just dirty water.
