I'm also a newbie and also have a 2ft tank running for 3 weeks.
Based on yr bioload of 4 anemones (probably tempted to buy them as they are attractive). You definitely need a chiller n a powerful protein skimmer.
Your corals may not be happy with the wavemaker as yr tank is quite small.
If you have a good filter, it should cause some movements of yr water already.
For my set-up, it did not install any wavemaker as the outflow from my external cannister filter is already causing moderate currents in the water.
I have consulted experienced marine hobbyist and aquarium shop owners, for 2 ft tank, you dun really need a wavemaker.
But since you have one, placed them blowing against your glass panel for indirect circulation. That way, it will not be so powerful causing too much stress to yr fishes and corals.
