Heres how I described my move a month ago on an earlier post:
I moved house 4 weeks ago and brought two tanks and a bowl with me. I brought almost all the water with me and didnt lose any fish at all.
Firstly the house we were moving to was 1hr away and we had access for three nights before final move.
I changed 10% water in both tanks each day but didnt use a gravel vac, just took water from the surface, this water is the best quality in the tank. I moved this water to new house in bin liners.. I thought these might be toxic but caused no problems.
On the night of the full move, I emptied 1/4 of the water into bin liners that were in kitchen bins, then removed all plants and decorations into theses bins to avoid having them crushed. I put a tiny amount of flake food into the tank and took 8 neons in one swoop from the tank, into a bag of water and then into a styrofoam box I got for free from a fish shop (thanks Joe!). Ditto for the rest of the fish. I then put all but 1/5 of the water into buckets lined with bin liners, which I then tied to avoid spils. The gravel I took out and washed a scoop at a time and cleaned the filter media in the remaining water, which was then dumped.
On the journey my girlfreind kept the filter media on her lap and swayed and shook the bags with 1/4 tank water to keep the bacteria alive.
On getting to new house, I put all the gravel in and decorations, filled the tanks with the water I brought over and left some new house water to age overnight in the buckets.
I floated the bags of fish in the tank and put carbon and Bio-Chem zorb into the filter to remove any toxins from the bags. Left them like this for an hour and then released the fish.
Next day I topped the tank up with the newly aged water.
As I said, its ben 4 weeks and I didnt lose any fish but you must try and be=ring as much water as is practical and keep the filter running until the last moment.
Your aim once you get to the house is to have the filter back up and running ASAP, dont worry about the fish, most have taken much longer journeys...
