I guess I am really inept! I have 40 tanks which are drilled and I just drain to the outside by rotating a standpipe, for water changes. My problem is that sometimes I want to clean the bottom. I can't seem to figure out a way to start a siphon in order to do this. Many years ago, I used to have a "Tetra Hydroclean" which was a gravel cleaning tube with a rattling marble in the top. You would just shake it up and down a couple of times and a good siphon would start. It worked like a dream! Alas, it is no longer made. I don't want to siphon to a bucket. I want to siphon to a regular garden hose which is about 25' long. Most of my tanks are bare with a little crushed coral at the bottom for buffering and for the fish to mess with. Filling is by way of individual temperature controlled outlets going to each tank so that is not an issue. How do I start a siphon for the hose which I can easily transfer from one tank to another as I do my cleaning and easily start it up again going from tank to tank. The squeeze bulbs I have bought are garbage.
