Got a new toy Friday. I have been using some of the Maxi-Jet mods, but they've just become trash. I ordered a Tunze 6100, and I will surely add another when the tank shows up. I imagine I'll end up with the multicontroller as well. Here is a shot of it in my 58 gallon tank. It is considerably more powerful than should be in that tank, and you can see i had to point it towards the front of the glass in order for it to not negatively impact anything in the tank. So far, though, the fish love it. I have it come on with the lights, so they get a break in the evenings.
