Koralia question

There are 2 different types........ Controlable, and regular. The controlable ones are 12v and for use on a wavemaker (mostly reef tanks). The regular ones are standard household current. Just put it in the tank and plug it in !

Picking the size is whats a little trickier....... I have a K3 at one end of my 125, about 10" below the waterline, and the unit is pointed slighlty upward. The outflow reaches about 2/3rds of the way across a 6 ft tank. Check the reef forums for better info on Koralias.

Oh man I was given a free Koralia1 and it sent ripples across 36" of water at under 6", pointed at an upper angle.

I forsee a koralia in my future but i have a question. Does every model need a controller or can you just stick it into the wall? Are there certain ones that do need a controller and certain ones that dont?

Basically, i just dont want to buy one and get screwed and not be able to use it because i dont have a controller.

Regular Korilia are fine...no need for a controller. What makes them so great is the low footprint in the tank...and the flow is dispersed vs just jet streaming ....it fluxes ...

They have a magnetic plate with the PH attached to it. The other magnet is placed on the outer side of the glass and it attaches by magnetism and a bit of suction.

Really good product. Reefers like me love them due to quality and good flow. My LPS corals shift and wave cause of the fluxing flow it produces ...vs just beating it down in one direction.

In my 72 I have 4 Korilias =) You mention a 4 foot tank..

the 1 and 2s are weaksauce. Go with the least a #3 x2 have them point towards eachother to disrupt flow to keep it from swirling the water is basic advise.

I have a 2 and a 4 in my fowlr(ex reef)

they move a lot of water.

I have recently started a project creating a custom controler for the 12V Koralias, and have had some success, though it's not prefect yet... So far it looks like they definately are 12V AC motors. You can drive them at about 500Hz with 12V DC and a microcontroller with a H-bridge like this one... http://www.sparkfun.com/commerce/product_info.php?products_id=8316 and get really nice flow out of the nanos. By changing the voltage along with frequency you can adjust the speed! You can use this to make a great wavemaker controller for under $50!
