Hey Wolf,
I haven't heard the hydro come up in a long time. I almost bought one eight years ago or so, but I heard somewhere that they have quality control issues with them. So I didn't bite.
I was always attracted to them b/c of that speed dial. I thought that was a great idea.
Recently, I stumbled on a 220 freshwater plant tank that had two of those pumps on it.
I guess if you find one that works that would be cool.
I have no idea if they still make them or if you can get parts for them anymore. Let me know. I am curious.
