Powerhead question
My LFS told me to buy a maxijet 1200. I have a 29 gallon tank. When I put it in my tank near the top and turned it on, it seems like everything in my tank can't handle it! My two clowns swim fiercely against the current in the opposite corner.
I was worried so I turned it off. Is this normal? |

Turn it back on. That's only giving you 10x flow in the tank at 295gph. Most strive for 20-30x flow. Honesltly, you could put a Tunze nanostream 6025 in that tank no problem (660gph). Flow is your friend.

Am I doing it right with it the end pointing upwards towards the surface of the water like the instructions said?
Also, is there any way to hide it? I have it at the top of the tank and it is just ugly...can it be at the bottom of the tank behind some rock? |

Like stated above, flow if your friend. They are ugly, yes, but it wouldnt do any good if the flow were reduced by a rock. I have two 900 in my 20L, one on each with the hydor devices on them.

you might want to think about a spray bar....(maybe DIY)....that would help "control" the direct force yet still retain flow....

Yes, If you put it in the back,upper right corner-then aim it at the front upper left corner,,and with more powerheads added you can aim the next one from the left upper corner to the lower right corner,so currents collide and give a closer resemblence to natural water movements in the reef. Always have at least one powerhead breaking the water surface for oxygen and gas exchange..Hope it helps.

How do closed loop systems work? Am I correct in assuming that this would reduce the need for a powerhead that is big and ugly?
I have a 75 gallon tank I'm setting up and it already has an overflow and holes drilled for the overflow. Would it be worth it taking the tank back to my LFS and have it drilled for a closed loop system? Also, how much money would the components cost for such a system? |

Also, do the powerheads HAVE to be at the top of the tank? or can they be placed near the bottom or center?

A great example of a closed loop can be found HERE also if you go to Melev's main page he has all kinds of DIY stuff. It is a great site.
