3. As a rule, the aquarium costs not on a floor, and on any eminence. Substitute a bucket nearby so that its top part was below an aquarium bottom. If the eminence small, is more comfortable to take the basin suitable on volume.
4. Take a hose rather flexible, but at the same time it should not form breaks. As it is necessary to use it rather often, it is better to choose its once for many years. Its length has to be at least 2.5 times more than aquarium height.
