I'm not sure how would be best to go about selling this, so i'll list it as best I can and please use the Q&A.

It's a self contained fishroom, double insulated large wardrobe size. I used it for breeding bettas but time constraints meant they had to go. Built from good solid treated timber framing, about a year old. All inside double layered with 2cm polystyrine. Outside is lamiwall. The doors are treated ply, double insulation inside, and sponge seal stuff around edges. However they aren't quite straight and square - but do close tight and keep the heat in.

I was running it with a 100w heater, and all levels kept a steady temperature throughout a king country winter with very little power usage. There's an air pump with two outlets which goes into 2x 3-way splitter taps, making 6 lines for running sponge filters. The ground level space has a door so it can be used as storage, I pile all the food and nets and things in there and it keeps them out of the way.

Tanks are - Bottom shelf, 2x roughly 2ft tanks, one slightly larger, one slightly smaller. Middle shelf, 3x 1ft cube tanks. Top shelf, 1 strange long low tank, and one which is somewhere between a 1ft and 2ft.

There's a power lead hole in the left side wall at the level of the bottom shelf, and the top for the top shelf. I plug these with a piece of poly when not moving cords around. The left side panel is screwed, not nailed, so it can be taken off to slide in tanks to use all the space without moving any others.

The cons - There's not as much 'elbow room' as I would have liked - the space between shelves is a bit short. And it's in Taumarunui. The framing is all screwed rather than nailed, so if someone from auckland was keen to 'purchase and assemble' I could take it down to a few pieces and move it up there for you to put up. Otherwise, if anyone's keen on the tanks etc alone, then make an offer and i'll change the auction.
