New Hydor Koralia powerheads

[plancton]

Have you seen the new Hydor Koralia powerheads, they seem sweet and cheap, plus they consume low voltage, does anyone know if they heat up the water?, can they be run with a wavemaker?.

The Koralia 4 seems to have a bit more flow than my current SEIO 110 and they are the same price.

[Entropy]

They are awesome! Heat transfer is much lower than the Seio's and power consumption is less as well.


The only downsides IMO are the size (big), and the funky orange propellar.

[plancton]

but would the KORALIA 4 be bigger than my current SEIO 110?

[AZDesertRat]

About the same, just a different shape. Much better power consumption though.

I have four #4's in my 180 Reef. They are hooked up to a wave maker.
They are not that good with wave makers because when they kick on the prop gets pushed forward into the housing. It goes bak in a couple of secs so if you don't mind the noise.

[plancton]

I bet that bak would also end up breaking the prop. But its ok, I have a wavebox.

I only keep my SEIO110, the return pump outlet and the wavebox on my 175 gal, according to me that's enough flow, what do you think?

I would much rather use my maxi-jet modded pumps. And now Premium Aquatics sells them for $19.99! The 1200 modded maxijet puts out absolutely awesome flow, probably greater than the Koralia 4! http://www.premiumaquatics.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=AF-SF1600&Category_Code=Maxijet

I've got my maxi-mod pumps on my wavemaster wavemaker, no problems after more than a year, just a little noisy for the first couple seconds. :rollface:

have you tried the one from premium?? I like that holder that comes with it

[AZDesertRat]

At three times the wattage too! Koralia #4s claim 11 watts, I have tested two of them with a Kill A Watt meter and find its actually 13 watts. MJ1200s claim 20 to 23 watts depending on what year it was made, and thats at 290-295 GPH, kick it up higher and the wattage will go up accordingly. Still not nearly as efficient.

I've heard bad things about the Koralia's on wavemakers though.. Thats the main reason I dont' want to use them. Since I haven't had any problem with the maxi jet, I'll just stick with it. And no, I haven't tried the Premium Aquatics mod yet, it should arrive today. I'll keep you guys posted.

[AZDesertRat]

Most pumps like a Koralia, MJ, Seio or others do not do well with multiple starts and stops. They rattle and sometimes try to start backwards. The controller like a Seio Multicontroller does not start and stop the pumps but slows them down and speeds them up continously which does not cause the same problems.

[VaderWS6]

Ok, I set up the maximod from Premium Aquatics last night. Its absolutely awesome for the price! No problems with start and stop on my wavemaker, very very slight noise. Awesome flow, chaotic flow! I've got three of these 1600gph maxi mods in my 75 gallon reef on the wavemaster. Its the flow I've always wanted! :beer: :dance: It even creates a sand cyclone in different areas of the tank every minute or so! I've got one in the back blowing across the top, and two in the front on each side, which blow into each other causing some very realistic currents! :rollface:

[plancton]

My opinion on maximod = expensive + you have to buy the maxijet + more wattage + more heat + we don't really know if the prop will get screwed up with the wavemaker

[happyface888]

I did my own mj mod in the end bought a koralia

[AZDesertRat]

See if you can get your hands on a Kill a Watt meter and see what power consumption is on the MaxiMods. I'll bet its close to 3 times what a Koralia draws considering the stock MJ is already almost twice as much power. For three MaxiMods at I am guessing, close to 30w each, I can run my closed loop with an OR 3500 60-65w) and OM Squirt and have about 30 watts of power to spare.

[mile sq. reefer]

You know how to stop the rattling? You leave them on 24/7 in the corners of the tank, opposite sides of course, and have them crash into one another. Provides some nice random flow.

[chris4869]

I have 2 Maxijet mods (with magnets) and 2 Koralia 4. I kept the 2 Koralia and retired the Maxijets. The Koralias seem stronger, and their ability to aim won me over. I wouldn't use them on a wavemaker either.

I'll be replacing the Koralia's impeller with the Maxijet mod soon.

[tang fever]

Desertrat, I'm not sure that power consumption will go up. By changing the pump casing and reducing restriction, you'll probably end up with close to same power with 5X flow. I'm sure someone will let me know the facts soon though.

[AZDesertRat]

Increase the flow you increase the work requirement. Increasing head with a restrictive impeller housing reduces the work required as it moves less water and lowers the wattage.

[tang fever]

Tell me why a koralia's so efficient???

[muzzlefish]

Here is the wattage of the Sure Flow 1600 on the respective power heads:

400 - 11w
600 - 11w
900 - 11w
1200 - 17w

[aninjaatemyshoe]

Really, every propeller pump is tons more efficient than typical powerheads for the purposes of circulating water within a tank. This has to do with the fact that a propeller is far more efficient at moving water than an impellar. There is also less restriction on the outflow than with a powerhead. Actually, I don't quite understand why propeller pumps are such a new thing to aquarium keeping. Someone had to have thought about it way back when...

[AZDesertRat]

Much better than I thought it would be. Did you do those tests yourself or is that a number you got from somewhere?

[Fishbulb2]

All of the original testing on the DIY maxi-mods showed that they used much less power than the standard maxi-jets. You just have to dig up the original thread but they tested it with a kill-a-watt.

[muzzlefish]

A Retired Electrical Eng. Professor from UW Madison helped me do the tests.

[AZDesertRat]

Thats good. Its still slightly higher than the Koralia #4 at a claimed 11 watts which I found to be an actual 13 watts. Much better than a stock MJ though!

[muzzlefish]

I just tested these powerheads with a New Watt Meter.

Seio 1100 = 28.2w rated at 21w 1100gph
Seip 1500 = 41.2w rated at 34w 1500gph
Koralia 4 = 17.6w rated at 12w 1200gph
Tunze 6060 = 19.5w rated at 13w 1600gph
SF1600 on 400/600/900 = 11.3/12.4/12.6w 1600gph
Vortec on high 38w Rated 35w 3000gph

Im having fun testing powerheads

[AZDesertRat]

Both of my Koralia #4s came out at 13 watts?
An Oceanrunner 3500 with 5 feet of head was 55 watts, OR 2700 needlewheel was 39 watts, OR 3500 on a closed loop with a OM Squirt was 62 watts, MJ 900 was 7, MJ 600 was 4 and MJ 400 was higher at 5.

it all in the way they move the water... one is centripetal force and the other is with a prop pulling/ pushing water... the centripetal force ( regular pump) uses exactly that.. it spins water inside a chamber and the force water to push outward.. the chamber will have a outlet.. due to this outward force water excapes thought area of least resistance.. so in essance.. it wast a lot of power just flinging water and forcing it to exit the chamber...

prop driven pumps are also exactly that... if you look at propellars or even fal blades... the 'back' of the props is designed to cut/pull in air ( or water in our case) and pushed out the front.. they use less energy cuzz they pump only has to move the prop to move water.. no extra ..... ( the other uses paddles to fling the wawter as to say.. and as you may know.. water resistance is srtong so the pump has to work againt this resistance and then some to get this centripetal force it needs)
