Hiya, guys! I searched around the forum and got some good ideas on which powerheads seem to be good and the best places to put them, but I'm still undecided. I don't have the tank yet, but I know what it will be- a 4x2x2' 120g with a low profile shadow type overflow, eventually a mixed reef. I'll likely be using an island type scape. I have a couple of different configurations in mind, and since this will be my first reef tank, I'm not sure which will be best.
Option 1: One powerhead on each side of the tank blowing against each other, with one on the back wall blowing towards the front. The powerhead on the back will be somewhat smaller, and placed lower to try to eliminate dead spots in the back of the tank. Or should the smaller dead-spot-eliminator go on one side of the tank, further back and lower than the bigger one providing primary flow?
Option 2: A gyre type powerhead on one side, with a more conventional powerhead on the other, programmed to move the point where the two currents meet around the tank throughout the day. Variable turbulence is apparently a good thing. A dead-spot-eliminator in the back- either on the back wall, or along one side.
Option 3: A gyre type powerhead on one side, with two powerheads in the back corners angled towards the front.
What do you think about these possible configurations? Would you do something entirely different? Do you think the dead-spot-eliminator powerhead is even necessary, or should I wait and see where cyano/dinos show up before placing one? If I go with a gyre type powerhead, which would be sufficient for a 120g without blowing my corals off the rocks or sloshing water over the top? And I'm still internally debating on whether or not to get Neptune WAVs or Vortech MP40s. I'd really appreciate any input or advice you may have. Thanks!
