Okay So....

I have a spare tank that i am going to make a "semi agressive" tank out of.

I just want your opinion on what brand of filter i should buy. Maybe a what brand and why sort of thing.

Price is not an object.

WHAT I WANT TO KNOW:

-WHAT BRAND OF FILTER?
-WHAT TYPE OF FILTER IT IS?
-WHY YOU LIKE THIS PRODUCT.

How many gallons is the tank? Then I can help you.

as fresh water fish lover said, without knowing tank size, it's hard to give advice.

However, if money is no object, and the tank is a decent size, how about an eheim external? A lot of people say the eheims are overpriced and fluvals are better value, but the lfs where i worked a few years ago had eheims throughout, and they had been running for 7 years+ with only one or two failures out of about 60+ filters over that time. After seeing that, i have always considered eheims to be very hardwearing and reliable, and i think they are worth the extra $$$.
Others will most likely disagree!!
