Bi weekly Discusion--- Flow part 2

[tims]

Well Gang ,
we just had a really long bi weekly on Flow. we covered a lot of things.( you will find it and many more in the archive section!)

I would like to continue on with Flow, but go in a different direction.
What are ways to have flow in our tanks and systems?
i figure we can get a list and break them down.

Power heads

[gman0526]

1)Powerheads
2)Closed loop systems
3)Surge Devices
4)Waveboxes
5)Return pumps
6)Mechanical Filters (canisters/OTT)
7)Water directors (SCWD, swirls,etc)
8)Eductors/penductors

Sure there's more just can think of any at the moment.

5 more than I thought of lol.

only thing I could add would be an air pump

Stream pumps

I did see a tank run just by air
it was about 90-120 gal tank, with a very large closed loop system
the water exsited out the right side of the tank
thendown and under
to a large protien skimmer with an algea scrubber at the top
the air bubbles would pull the water throught the closed loop

heheh.... boy you guys and gals are on it tonight!!

Okay so now ya made me have to go ing to the next days notes

Lets break each one down. ( a little at a time pleaseeeeeeeeeee)

power heads..
types?
how they work
( pics are cool if you have them)
pros for using them, Cons for using them?

I'm searching for it right now

it was at the trade show in Chicago about 3-4 years ago

found it

I believe most all powerheads could generally be described as devices consisting of a sealed electronic motor that electro-magnetically drives a propeller/impeller affixed to a magnetic shaft.

The two main types (that currently come to mind) would be differentiated by the water propulsion device they use:

Some are directional and use a propeller type device (Like the Hydor Koralia in the first picture) while others are multidirectional and use a flat bladed impeller of some sort (Like the MaxiJet in the second picture).

Does that mean we arent allowed to talk about closed loop systems yet??

I think so, we shouold have beat Kelli to the answer

PH's are an econimical way to move water with no filtering effect
the pro's are
1) cheap
2) easy to place
3) easy to move

con's
1) can be difficult to get int he spot you want
2) should be cleaned often
3) beak down
