Thanks for the pic! Kelly |

It looks like it should, assuming (3) is open with no pumps, no valves, etc. My veggie filter (1) is actually above the koi pond (2) and I use 2 Oase 3700 GPH submersible fish basin pumps to move the water. While you aren't really supposed to pump the bottom uphill, it is working reasonably well for me. I've got a tanin problem and a bit of an algae bloom because I don't have enough plants yet, but it is working reasonably well. |

A Lesson On Water Levels
OK Jeff,
This is what I think? You are playing with complex laws of physics. I try to work with the more simple aspects of gravity! Pump up, gravity flow down! What goes up must come down. So I will either elevate my VF, pump up into it, and let the water flow back into my pond or I will have my veggie filter lower than the output portion of my pond. Of course the output portion has to be much lower than the top of the water level in my pond. Say your VF is 12" lower than your pond, then the output portion of your bottom drain from your pond can be 6" lower than the water level in the pond. Then simply pump the water back into the pond from the VF. No siphon to deal with, no head to calculate, and no major backflow to deal with. The lowest your main pond can go down is to the level of your bottom drain out put or 6" low. And your veggie filter can never back flow back into your main pond. My 2 cents. -- _______________________________________ "The difference between 'involvement' and 'commitment' is like an eggs-and-ham breakfast: The chicken was 'involved' - the pig was 'committed'." http://community.webshots.com/user/godwino "BenignVanilla" m wrote in message ...
