Surface Agitation?

[Raibaru]

I got a Vortech which I'm just toying with and seeing how it runs on my 36g, but I plan to upgrade to a 70g in a few months time.

One thing I've noticed is that I no longer have much of the surface agitation I had with my other pumps (obviously since they were about 10" deep but pointing at the surface etc). Is there a way to position the pump to provide better surface agitation?

I pretty much run in reef crest mode (not much luck with waves in this size tank, but no biggie). If I push the pump closer to the surface it drags down a funnel of air. Will this cause harm to the pump in any way? I know with my Koralias it really grinds hard.

If I try harder to get some wave action will this help instead (Any advice on getting waves with a single pump in a smaller tank?).

Beyond that I'm very happy with the pump so far. A bit noisier then I thought it would be, but easily drowned out by my loud AquaC remora and with the night mode it doesn't interrupt my sleeping any way.

Very happy with the product so far!

Raibaru-

To improve the surface agitation you can place the pump as close to the surface as possible before a vortex forms. This will vary depending on what speed your pump is run but usually you can get to about 4" from the surface safely. That being said, a vortex is only annoying for you, it won't actually hurt the pump.

Do you have an MP20 or MP40w? With an MP40w you will definitely be able to make a wave on a tank this size. Sometimes though the bow will affect what kind of wave you can make.

Yea, it's an MP40W. What would you suggest to try and get some wave actions going. The tank is 30" long too.

Turn the speed to max in short pulse mode then start at a high frequency and slowly work your way to a slow frequency until you hit the resonance point. Make sure to wait about 20 seconds in between every time you adjust the knob to let the wave form.
