Vortex or Koralia?

[don.ald]

my experience is MP10's can be noisy.

Sound is definitely a factor with any VorTech since the electrical motor is outside the tank, therefore no sound dampening via the water which is the case with conventional powerheads. I have no problem dealing with the sound (I don't refer to it as noise but that's just me), since VorTechs produce much better flow than anything else I've encountered. I use the night mode with my two MP40s, so the sound level drops quite a bit in the evening. The sound is most noticeable if ramping up and down from 0 to 100% power in short pulse mode. I use Tidal Swell Mode so the speed changes are more gradual and not as noticeable. If your tank is in the bedroom and sound is an issue, then yes, you probably need to rethink using VorTechs. Other than that, I found most other ambient sounds such as light fans etc. drown out the sound of my VorTechs.

I went to ridiculous lengths and expense to make my system quiet. (It's in my office/recording studio) I bought 2 Red Dragon Pumps, Bubble King Skimmer, etc. The vortech is one of the loudest things on the tank, however, I just can't replace it with anything else. the flow is just too perfect and my corals and fish are too happy to mess with it. It's the one thing that was worth having a little noise.

I just put one in my 40b. it replaced a korrila 1, 2, and nano. moves everything nice and the corals look happier after a couple days of it running. I do not think 2 would be needed in my setup. Got the wireless so that another could be added if i ever get around to upgrading my tank.

I have been debating getting a korallia or a vortech for my RSM250..

Vortech seems to be the way to go...

What size should I get?

hahha now im having the wireless debate.
although something tells me with over 1000 gph flow at max, I should be OK in a 40 breeder with just 1 mp10.
where the best place to put it?
pointing from one side to the other?

go with the mp40ES and just dial down the flow. I had a mp20 full bore on a biocube 29 and my sps loved it. then you can always use it later if you upgrade

Bought an MP10 for my 40 gallon breeder and currently have it sitting on the left pane of glass.

the anenome is flowing like never before, the xenia the same and the poor fish are all wondering what the hell's going on haha.
