OK, everyone's had a couple of days to play w/the 25's, what setting(s)has everyone ended up with? I think I blew 2 or 3 fish and a Turbo outta the tank on my initial start up! Once I tuned it down a bit I played w/the wave function and had the perfect storm wave in a couple of minutes! Small pumps but very powerful for sure. I ended w/the ELSE setting on S3. Kinda waiting to see what everyone else has found to there liking. My dimmer feature is working like a champ as well. I have 2 in a 75 on opposite ends working against each other. Thanks Jeff for getting all of this together and all the headaches you had to endure!
