I am looking for a powerhead, and then realized that I have no idea how powerful it should be. so I remembered that there was a thread in the "Getting Started- Saltwater" section of the forums about all the things you need for a saltwater tank. so i looked at what it said about powerheads and it said this (copied and pasted):
"The use of a power head to move your water is necessary with a SW tank and a tank turn over of 15-20 times for FO/FOWLR/REEF is good since all benefit from good current. I would get at least two. Point them upwards and at each other to create a slight ripple on the surface for good oxygen exchange and convulsing currents. If the PH doesn't come with a pre-filter/screen then consider adding a sponge to keep fish/inverts/sand from getting sucked into it."
What I want to know is if for my 15 gallon tank, a 225-300 gph
powerhead would be good, based upon what is said above. thanks for the help
