Thanks, mw & achilles!
achilles, I'm really glad to hear they're good. I have the 6000 with speed control and a 6080 without speed control (that one was the only one they had in stock, so I tried that first). I do notice the fish like them!!! They all got in line to swim in the current!! I can't wait to see if I can tell a difference in the corals! Yeah, that was so interesting about the eductors. I gotta find some people who're using them and ask more!
Hi jks, I got them at marine depot;

As for the eductors, I know aquatic ecosystems has them. Also, another link to another place that sells them;
