I had to go back and review your other post. Honestly, I'm not sure breaking down the tank is a good idea. I would be surprised if the source of your organics is something in the tank. You can tear it down, but until you find and correct the source of the organics feeding the bacteria you should expect the clear slime to come back.
If you want to tear it down anyway, it would help if you could post your current livestock and how long you think the tear down will take. Definitely an HOB, heater, probably an air stone or small powerhead. Lighting. PVC fittings or other form of shelter. That would be a bare minimum.
