Took out 2 PH to try to see if that was causing bubbles...

He said he turned them off and still has bubbles.Kicking upi the SB surface is a good thing and a little extra flow goes a long way.

Koralias by there prop design are not made for controllers.Then by his placement they actualy lose movement.

I disagree Lance, they work fine on interval timers---if they make a clunking noise then the simple fix is to but a piece of plastic tubing over the exposed shaft
Hydor has never said you can't---IMO the clunking sound has mad guys believe you can't

BTW hydor is coming out with a controller and a brand new line of pumps
The controller for two pumps is retailed at 425 bucks and the new pumps are way more in price to.
It is a little rediculous when the old ones work fine on interval timers
I have a one, two and four on that interval timer

IMO Hydor has discovered that the popularity of the Koralias has made their product under priced and are looking for subtle ways to increase the price on them

[MrRoo]

I said I either have small bubbles or sediments. With the K2's out I have less.

[Aquarist007]

all that info above has been reported on this link
the link to Hydors controller is on their too

What are the dimensions on the tank...?

Here's my old 55 once it was pretty much raided, but you can still see the placement of the K3's in the tank.

I didn't have any issues with bubbles or sand.

[seapug]

thanks for the tip on getting Koralias to work on a timer, capn! Good idea. Do you have any suggestions for installing those plastic tubes on the shafts or will anything work?

Swifty,

I think the K3's are too much for my tank, I think I should 2 more K2's. They either blow the sand or cause bubbles at the surface because of too much flow.

I use a k3 in my 30 gal with no problems---I just make sure it is directed more at the glass so it bounces off it

[MrRoo]

36wide x36high x24wide

[Tswifty]

The sand build-up on the right is compliments of my trigger, who got mad everytime I leveled out the sand bed and would move it all into a pile in the corner shortly after.

I wouldn't rule out the 3's just yet... It's all about placement... IMO I would start with the 2 -K3's in the tank. Once you get them settled, add the K2's to address any low flow areas or dead zones.

Ok I'll see where I am at tomorrow with the K2's and go from there with the K3's.

[seapug]

The reason why they aren't intended to be used on a wavetimer is for the reason Capn stated-- the propeller sits loose on the shaft so it rattles when they start up until the prop gets seated. Doing this over and over might damage the prop. If you can eliminate the rattling there's no reason why they wouldn't work.

that's not from Hydor and it says not intended---nothing from Hydor saying "do not use on an interval timer"

besides enough experienced guys on here are using them on interval timers with no problems----find me one reefer that has burned one out prematurily by running it on an interval timer

it is such an easy fix to quieten them up--the noise is coming from the shaft banging into the cone where it rest==the plastic hose over it dampens that from happening

[seapug]

hmmm...so a small piece of airline tubing might work, eh?
Sounds like I have a weekend project. Thanks!

p.s. Apologies to Mr. Roo-- didn't mean to hijack your thread.

[demonsp]

I guess are experiance is differant as i see many threads on the misuse of wavemakers and that koralias arent made for them. If you use only this in your tank for water movement then it may take time to show adverese results so just keep this thread in mind.

well, you can buy quite a few replacements before you spend the $400 on the ones Hydor is making that probably have nothing more than the added piece of plastic Capn mentioned.

[Tswifty]

I'm just curious and definately not trying to "fuel the fire" here... but what potential problems do you think may arise from running them on a wavemaker?

[demonsp]

Oh and Capn. you use 1 K3 in your 30 on a wave maker?

[demonsp]

God where to start. Depends on there size and placement and intervales. But from my experiance any koralia on a wave maker isnt right.

I actually believe the new Koralia wavemaker capable are DC instead of AC so they always start in the same direction.
