I'm new to this group so apologies in advance if this has been discussed.

I have a 300 gallon indoor pond (started off as a winter haven for my
outdoor pond fish) and I'm having a lot of trouble with ammonia levels.
The
pond is probably overstocked with goldfish but they all look healthy. I
get
ammonia numbers off the chart using a standard test kit.

I can provide construction details including filter type but it would make
a
long post. I'll be glad to do it offline.

Anyone else have an indoor pond? Is there a newsgroup somewhere that
focuses on indoor ponds?

I plan on a temp one this winter, to try and overwinter some plants. I'll
let you know how it goes. My big concerns are light, and my ankle biters.
