Jason: Those MJ mods are wild! Yea they will give you some flow!

how big is your tank that u have four koralias?

I want to get some more flow into my 125 gallon. I like the looks and reported
operation of the Hydor Koralia pumps...

But cannot decide between getting two #2 pumps or one
#4 pump.

I don't plan on putting on switching timer.

Both $ and power consumption wise, for same amount of flow, the single #4 makes more sense (I am thinking...)


Any suggestions??? (and if less $ elswhere)



Hydor Koralia 2 Aquarium Circulation Pump
* Flow Rate: 600 GPH
* Power Absorbed: 9 W
* 115 V 60 Hz
$27.99




Hydor Koralia 4 Aquarium Circulation Pump
* Flow Rate: 1200 GPH
* Power Absorbed: 12 W
* 115 V 60 Hz
$33.99




While at it think I am going to get the Nano model also from same seller (mtndewman1) wonder, is this the same "mtndewman" that used to post here long ago?


What would you think best choice for 12 gallon NanoCube?

Hydor Koralia 1 Aquarium Circulation Pump
* Flow Rate: 400 GPH
* Power Absorbed: 3.5 W
* 115 V 60 Hz
$19.99

or

Hydor Koralia Nano Aquarium Circulation Pump

* Flow Rate: 240 GPH
* Power Absorbed: 3.5 W
* 115 V 60 Hz
$17.99

Am thinking "size" may be significant issue here. The #1 sounds like too much flow for nano...



Any tips or thoughts would be greatly appreciated.

Thank you in advance.

Wound up getting two #4's and One Nano Koralia...

Turns out 1 #4 was more then enough to meet desired flow needs in main tank. (So now I also have a "backup")

Makes all the difference in the world having little one in Nano.

Am happy.

Thanks all for above.

(Jason, will try Maxijet Mod when need an upgrade...)

Don't know size of your tank, nor what kind of present flow you have.

Size pump needed depends much on above.

I added mine because I needed to redirect existing flow and get some additional surface water turbulence.

You may just need one #4 instead of (2) #3's.

Again, hard to say.

He's got one side high, pretty much for surface agitation then the rio in about the middle on same side, and on other side he has other koralia a lil' low but not on bottom of tank. gives him flow e-where, no dead spots.

That was a little confusing. I have 2- #3 Koralias and 2-#4 Koralias.

I run the 2-#4s and 1-#3 and keep the last one as a spare.

My tank is a 90 gal and the flow coupled with the return pump is 35-40 times tank volume.
