As some of you may know, I'm a great fan of surge devices. While planning my 6 gallon nano, I couldn't think of any easy way to plumb a surge device to it
, so I have to go with 2 PHs and an extra wavemaker. I hear Rios are terrible on wavemakers...what's a good brand?? The best choice would be one with threads for PVC and in the 100 gph range.
