Thank you for your question mitchell1111. While you would not stick the siphon into the substrate the same way you would when using gravel as a substrate this type of product would still be advised. You still need to do routine water changes and if you are pulling the water out of the aquarium having the rigid plastic end will help to diffuse the water pressure pulling into the siphon hose. This will help to not pull out as much sand when removing detritus from the aquarium and will help the fish from being siphoned out.
