I appreciate the advice, Carl. I think I'll give the Zoo Med PS20 a
try.
I don't want a strong current - I plan on having placid fish, like
angels.
When that powerhead dies I'll try one of the others you recommend.

I was happy to see a nice Festivum at the local pet store today.
Are Geophagus Jurapari and Kribensis still commonly available?
