Some pictures are on the way.
However, this tank is no more in it's current format. The live rock, most of the substrate and the fish have been moved to a larger tank. This wasn't the original plan, but the tank became free and I couldn't resist it.
I was happy with the 3 foot long, but just going to a tank 4 feet by 16 inches base is a big improvement. The fish behaviour is different. Moving from tank A to tank B took about 2 hours last Sunday. I spent Thursday cleaning the tank with freshwater as best I could. I then stuck in 30 litres of 1 and a half strengh saltwater to kill any freshwater algae et al I'd missed. On the Friday I did more cleaning and scraping, then empited the tank, cleaned with freshwater and then put in 60 litres of water and added salt.
On Saturday I started by moving 20 litres (I use 10 litre buckets by the way), and putting in , with acclimation a hermit, a Trochus snail and a leather coral frag to check, I guess for any toxicity. Nothing happened by the Sunday, so I then moved the live rock. I did this by putting it into buckets with water and acclimating it to preserve any sponges et al that have appeared. I also shifted, by syphoning into a bucket, about half of my now live sand.
Once this has been done, and some preliminary aquascaping, I moved another 20 litres of water + the fish.
Basically these fish have had a colossal water change into a new tank. Left behind is a tank with some sand, a lot of coralline and 6 inches of water. I've left a powerhead in there to provide water motion, and my T5's are in the hood to light some frags I have kept in there.
The new tank has a total of 2000 lph of water movement (more to come), but only NO lighting so I've had to move my corals into the top of the tank to get as much light as possible - for them water depth is only a few inches. So far all is well, and I don't expect any problems.
The 30 gallon was fun, but in all honesty this will be better, for a limited cost to upgrade.
