Please no. tangs have no place in a tank smaller than 55 gal
My question is will a maxijet 900 be enough watercirculation to start when used with a protein skimmer, and an aquaclear 200 filter?
My first response is no. It wont be enough circulation. My second response is what kind of skimmer and what pump is attached to it. Will the aquaclear be run with or without a filter cartrage?
The truth is I cant say with a difinitve amount of authority exactly how many powerheads you will need to provide proper water circulation around your tank. Expecially if you put live rock init. There are just so many vairables that affect water flow. Rock placment, amount of rock, volume of water taken up by rock, placment of powerheads, etc.
Basicly its a trial and error. You put your atnk up and decorate how you want. You put the powerheads in and see how your water flow is. Maybe you reposition them. Maybe you have some dead areas and you need to boost water flow to those spots. So maybe you need another powerhead.
