I liked how it works. I removed the film from the bottom well.

Gerçekten çok iþe yarar ve pratik temizleme iþini çok güzel yapýyor tavsiye ederim.

Easy to use and is great for so many uses including my favorite, draining the tank. easier than a syphon and no water in you mouth :0)

very strong and a pump that works. If you want to use the pump in, if you want to clean the bottom. it just works and is very strong. I would recommend.

sucks the sand up alos really needs some way off reducing flow like a slide switch that adjustes the speed of the motor
