I don't use it on my betta tank but i do use one on my community tank. This is the one I use... http://www.walmart.com/ip/Regent-Pow...-1-ct/10313131
Make shore that you filter is strait up and down not leaning. Also you never told me how big you tank is. If it is a ten gallon like my betta tank i use rocks to hide the sponges. Place in in the corner of your tank and get good flat rocks from you local pet shop and stack them around the filter. make shore you leave big enough gaps for water to flow threw to the filter.
If you decide not to use a power head, try to keep the top of the tube as close to the surface of the water as you can. this will do 2 things, 1 it cuts down on the noise, 2 it reduces surface agitation but keeps enough to help aerate the water for your bacteria.
hope this helps
