How can I regulate the suction with the sera gravel washer?
I purchased the sera gravel washer. However, I do not quite understand how I am supposed to use it. Every time I want to clean the gravel, quite a lot of water gets into the bucket so I have to empty the bucket rather frequently before I can continue cleaning the gravel. A 10 liter bucket fills within 25 seconds. Please tell me how to use it correctly.
you can regulate the water flow and, correspondingly, the suction by simply covering the free end of the hose partially with your thumb.
