Koralia # 4 not as good as #3

Ricky1066 · 03/19/2008, 05:02 PM

Ok I just got my order from Dr fosters and I orderd the #4 kpralia after putting it in the water it seems to have half the power the #3 has

I bought it to push the water across the top of my tank and honestly It is not reaching the whole tank and my #3 does

anyone have one #4 is mine defect or are they that way

SteveNMegz · 03/19/2008, 05:15 PM

we have 2 #4's, what are the dimensions of the tank???

ours is 48"L and both of the reach teh ends, but you wouldn't be able to feel it (just see stuff blowing)

ROBERTCHAPA · 03/19/2008, 05:23 PM

MY 4's push water across my 90g both do a good job almost too much

Tswifty · 03/19/2008, 05:31 PM

I have no experience with 4's, but I love my 3's!!!

Aquarist007 · 03/19/2008, 06:02 PM

sounds like a defect---its guaranteed, return it

BLKTANG · 03/19/2008, 06:04 PM

Here's a test you can try.

My k4 will pull a whirlpool on the surface if its any less that 4" from the surface.

rbursek · 03/19/2008, 06:08 PM

If you read the instructions when you first put it into your tank, face the opening up to release any trapped air, that could be the problem.

seanb1 · 03/19/2008, 06:28 PM

my number 4s kick butt

Raato · 03/19/2008, 06:43 PM

I agree with BLKTANG my 2 4's will pull a whirlpool down 6 inches or so, at least.

protege · 03/19/2008, 06:43 PM

My 3s work fantastic

demonsp · 03/19/2008, 06:48 PM

I like koralias but think there better for addition or spot flow. I like a powerhead that has a flow control knob and duckbill tip for dirrection control. Then pointing them at the surface isnt a good way to use them.
I didnt read all replys but i wonder how many and what size powerheads you have in there now?And was there a reason you wanted them pointed toward the surface?

Logzor · 03/19/2008, 07:10 PM

I have had defective K4's. Does it rattle at all?

SteveNMegz · 03/19/2008, 08:31 PM

ours rattle all the time, we just assume its because of a bigger propeller???? or thought we might not have put that lil black washer back in the right way maybe???

our only pull a whirlpool down if theyre maye 3-4" below surface

seanb1 · 03/19/2008, 08:35 PM

another thing to remomber with korallias is that they dont really push water in any direction, its kinda all over the place.

i have mine at about15 inches from the bottom pointing across the tank and they move the sand on the bottom.

agreeive?fish · 03/19/2008, 08:36 PM

Got a #4 comming thursady if fed x gets it here on time..ill let you know how mine does

are you using them on an interval timer--they are not designed to run on them--that's usually when they rattle

SteveNMegz · 03/19/2008, 08:45 PM

nope, they're on 24/7. we can see both of them slightly moving back and forth from the propeller moving. only hoguht would be that washer, anyone know if the side that has a nipple on it goes up or down?

Ricky1066 · 03/19/2008, 09:12 PM

I put mine in and faced it across the tank about 2 inches from the top I have it on the side and it is blowing the water but from putting myhand in front of it and on front of the #3 the 3 is way more powerful

SO i am not sure if it is a defect I assume I will have to call dr fosters?

BLKTANG · 03/19/2008, 09:14 PM

yeah give a buzz,their coustmer service is top notch you wont have a problem.

Ricky1066 · 03/19/2008, 09:32 PM

Well I justhad my wife stick her hand in the tank and put one in front of the 4 and then the #3 she agrees the 3 is more powerful But the #4 is more widespread So maybe they are supposed to?
The #3 has a smaller hole so maybe it gets out faster But I will call

do all as korilia owners a favour while you are at it
ask them when the controller is going to come out for them that they have been promising for over a year

have you dealt with Dan at Mops in Hamilton. should give him a call and ask him that--he'll know.

SSpiro · 03/20/2008, 05:41 AM

I plan on ordering some #4's shortly for my 55g. Looking forward to it.

Nanz · 03/20/2008, 06:47 AM

Thats interesting...

I have 2 Koralia #4's on my 75 and 2 Koralia #3's sitting in storage. I bought the #4 to increase my flow and its definitely more powerful than the #3's

A.VOID · 03/20/2008, 07:57 AM

What do people recommend for a 55?

I saw one poster saying they're getting 2 x 4's for a 55. I thought that sounded like too much.

A pair of 2's (600goh) = 1200 gph or 20x+ water overturn. That sounds right to me/
