I am just wondering if I am doing my water changes in the easiet way possible. I have a 55 gallon tank with one Oscar and a 29 gallon community tank. I change 30% of the community water and 50% of the Oscar water weekly. The Oscar water gets siphoned right out of the tank and down the drain. The community tank water gets siphoned into a rubbermaid container and carried into the bathroom and dumped down the drain (we live in a third floor appartment). Then I fill another rubbermaid container with fresh, dechlorinated water on the counter and siphon it into the Oscar's tank. I fill another one of these containers and hand carry water into the community tank. It pretty much takes 1.5 to 2 hours. I saw a water siphoning system at the LFS today and was wondering if it will actually siphone water from a lower area into a higher area. Does anyone have experience with these or a good idea for easier water changes?
