Waterflow for 20 Gallon

[scunfcu]

I will be doing a 20 Gallon standard size ( 24x13x16 ) Nano.
- some sps, lps and soft corals

not sure which powerhead to use for waterflow. Thinking about using Seio or Koralia, which model and how many?
No sump, will be using Remora with Maxi-jet 1200 with pre-skimmer.

That is a small tank for different kinds of coral. Just keep in mind that coral besides stinging also use chemical warfare against their competition. So even if the corals are not touching they are releasing stuff that will adversely affect other carals and fish. You do not see it but you can see the results. That is why there are all these questions about why is this or that coral closing or dying. So if I were you I would try to keep to the same types instead of trying to get a mix that doesn't even grow that way in the ocean.

Thanks, I will be puting small amount of carbon media to knock out some of the chemical warfare. Question was do I go with one or two Hydor Koralia 1?
