Jeff I will e-mail you.
You ask about stagnant water. The only water in my pond that I would say is even close to stagnant is what's in the settling tank in the Nexus units. I think you're talking about the water that's in the TPR lines that are not working at the time. This was a easy fix. I just have the closed ones cracked a little. This keeps a little water moving through them all the time. It's not enough to do anything else. Brentwood, is that near San Jose? I'm hoping to go to Genki koi next week to pick up a koi that I got from Kevin.
Akai-San, I used a product called CIM to seal it. It's just about like using a liner over it. You can read more about it at
