Well since the cat-is-out-of-the-bag so to speak, I might as well tell you what I bought... I have a length of 1 3/4" ABS and a length of 3/4 " CPVC tube from CDN Tire last night, and a 1 3/4 cap. The idea is that the siphon will be one tube inside the other (which will be capped) and the assembly will be in its own small tank above the display. This will be piped down into a bubble settlling chamber at one end of the tank, and will flow strongly across the top of the tank and less so near the sandbed. I have yet to test my siphon... actually I put the pipes in the corner and haven't touched them. I won't until I get a bucket and some silicone. Then it's on!

I actually did consider using a solenoid but can't run the risk that it might fail (which it would)... stuck open, no big deal... stuck closed and we have a problem. So I go with the low tech method, and use other low tech devices to fix the issues with the first low tech device. If only the lighting was going to be this easy or cheap!

Do you have a pic of the proposed plan?
