ok, here's what I do. Since the tank is too heavy to carry, I get a bucket and a clean plastic cup. I use the cup to dip the water out and pour it into the bucket.Then I carry the bucket into the bathroom and dump the water. I do partial changes once a week and full changes once a month. Also, use a gravel vac or turkey baster to get the debris off the bottom. You can leave the fish in the tank while doing partials. I remove 50% of the water. Once a month I remove the fish and put him in a gladware container, dip out enough water to make the tank light enough to carry to the bathroom and dump the remaining water out. Then I take out rocks and decorations and rinse them thoroughly with hot water. Then I rinse the tank well with hot water in the tub. Then I put everything back in the tank, put the clean, conditioned water in and put the fish back in. Hope this helps.
