Chapter 7. First Inhabitants
While it was fairly easy to wait 6 weeks while the tank was being built, the waiting game had become agonizing once the salt was mixed and the cycle had started.
Originally I was toying with an idea of simply moving all small aquarium's contents in the new tank and hope for the best. It still makes some sense to me: the amount of established live rock and sand plus the bio load is not changing, only the total water volume and new media is added, neither should affect the cycle in theory. But after giving it some more thought I dismissed this approach as being too aggressive.
On the other hand I knew that to do things properly I'd have to run the tank for a couple of months with no fish/corals, seed it with some live rock, add a copepod colony and get a solid soup of all saltwater goodness before adding anyone. Though somewhat determined to do this earlier in the process, I decided not to proceed with this as well since it would take too long.
Finally I picked a semi-aggressive approach. I did everything I could to speed the cycle up:
I started taking ammonia and nitrite measurements every other day starting day 3. Both were at solid zero and remained zero during all of my testing. So I figured that all the steps I took must've done the trick and decided to move some fish over.
My first choice was the bicolour blenny. Right after I've put the net into the water both blenny and six-line wrasse went for the rocks and found shelter deep in the crevices. There was no way I was going to catch them.
I hesitated about picking my clownfish pair, but they seemed so oblivious to the whole process and were swimming next to the net so I decided to use them instead. To my surprise, the moment I started targeting them they realized this and changed their behaviour immediately. I've never seen a fish behave so frantically, they were literally freak out. That is probably one of the biggest differences between saltwater and freshwater fish that I've observed. The fish clearly knew what was about to happen and did not want it.
I was about to give up on catching the female when suddenly it leaped from the water and ended up in a plant pot that stood nearby. Now I was about to freak out. I grabbed the fish, it was covered with black soil and quickly dropped it in the new tank. The fish was clearly in mild shock. After a minute I caught the male and put him in the big tank as well.
For the next hour I observed how patches of soil were slowly coming off of the fish. An hour later the fish was fine and I decided to call it a night.
Here's a video I took of the tank and its first inhabitants.

Finally I picked a semi-aggressive approach. I did everything I could to speed the cycle up:
- took a few pieces of new rock and put them in my old tank for a few days so that they'll get colonized by bacteria
- added about 10 lbs of live rock into the sump
- put some used media basket filters from the smaller tank into the sump as well
- added some Seachem Stability
- dozed sparingly with ZeoBak
- every day scooped up about 1/4 of a cup of live sand from the old tank and dispersed it over the new sandbed
- stared intensely at the tank in search of other possible ways to speed up the cycle
