In response to marks post about the cost of the siphon system, that does seem a lil pricey for the fittings for the 8" siphon. The siphon system has been around for many years, but a company I buy my systems from has perfected it using elbows that are made for different slopes and using a screen on the vent pipe, to keep turtles, trash, etc. from blocking the vent pipe. They dont have a website yet, but their number is
1-877-387-5472 . They should be able to save you some money on your stuff too.I prefer to install siphons because of cost , but they also do a good job of removing the stagnant water from the lower levels of the pond, where as spillways alone and conventional overflows don't. They should be able to answer any questions about siphons or any of the products they carry. I'm new here but i think this a great site.
