How do you know? You shut down your filter, and cultured the
sand?

Reading my own comment, I'm realizing that this comment might
be viewed as sarcastic. Didn't mean it that way. :-)

Funny. I did take it as sarcastic. Glad you reposted. No, that is my
problem is that I am no expert, and I do not test the sand. Plus, I
have live plants in my pond so that must help my situation, along with
the skippy filter.

I know my water is in great shape. I have it tested often at the LFS.
And I know it is overstocked in a HUGE way.

I use coarser sand than what the "store bought" systems use (my reef
tank sand). Also the system is "homebuilt" Just peices of PVC glued
together.

When I first built this I was told that the bio would live for a day or
two if kept wet... As much I know and have researched. Will take a
look at the link you sent.

All the best

Carl
