If you are looking for flow, add a powerhead or two.

This much filtration is completely unnecessary. BUT, to answer your question, I suppose for the price it is a good deal. I still think it is extreme overkill, but nevertheless, a deal is a deal.
That is just the point, it isn't necessary, but it works great, they are cheap (I bought mine for 150 off cl with all media) to top it of it had ehiem media, with a reactor and an inline hydor heater it is absolutely perfect. Also don't have to clean it much with the little fishes I have in there.

I have 2 rena Xp-3 on my 75 gallon and find it perfect for what i need. I also feel its better to have 2 filters running rather than one big one incase one decides to stop working. You can get 2 XP-3's from Big als now for $210 shipped, using there promo code...well worth the money.

Since it is so big, your bio media does not have to be the expensive crap. Pot scrubbies, biobale, lava rock, etc are all fine.
Where do you buy these little guys?
