Power Head

That's what I'm using my penguin for, just to circulate the h2o near the bottom.

I guess I just don't see that they're necessary... with even half-decent filter outlet placement, I don't see flow through the tank as being a significant problem. For example, I occasionally add Aragamilk to several of my mbuna tanks. Aragmilk is... well... milky when you add it. After it's added, you can easily see the current flows in the tank. I'm always surprised how quickly and evenly the stuff is dispersed after adding it. In these tanks, what advantage would I see by adding the jet system?

I'm not just playing devil's advocate, I'm really intersted. I love to fiddle with new gadgets, but unless there's some demonstrable benefit to my fish or reduction in my work, I generally won't bother.

Thanks,

Jim, well it will depend on the tank, filters, etc - and unfortunately I don't have any great scientific data to support my theory - just my observations.

In my 72 gallon, I have a wet/dry sump with a corner overflow. My return thus comes up in the left corner at the top of the tank. I wanted more circulation at the bottom of the tank which is why I made my underwater jet system.

From my observations, I find much less gunk on the bottom of the tank to vacuum than I did in other tanks - and more importantly, I find my fish enjoy the jet system very much (different ones interact with it in different manners). the force is not enough to blow a fish away that a single powerhead may do - but it does create current in the tank at the gravel level that several species love to frolic in

Now if I had multiple filter returns and positioned them differently, maybe the same results would occur - I don't know

But I do find the jet system beneficial in my existing setup.
Again, nothing scientific - just conjecture based on my observations
