pardon my spelling. shoud i get an milenium filter? my friend from school has one and it's very cool. I have a 10 gallon tank with a hood, water [cycled], and some gravel. My friend's milenium has a little blue swich that makes the power stronger . will it be a waste to buy one or does it do anything beter or what? BTW i dun need a heater because i live in hawaii. . If not milenium what kind of filter would u suggest? thanks for the info.
