Problem: I have a 16 gallon (60l) nano tank with around 50l of water. I want to vacuum sand bed once a week with the water change. I must change 10% of the water, which means around 5 to 6l. If i use normal siphon vacuum cleaner i can't clean the sand so fast because 6l of water runs out way to quick.
How can i vacuum the sand properly without loosing too much water?
Are there any good battery powered vacuum cleaners?
