Need help selecting a fliter. (See post)

The two that I am looking at are Marineland Penguin 200B Power Filter and the Penn Plax Cascade 300 Power Filter.

I want to put this on my 30 gallon tank. I know overkill but that is the way I like it. Not sure if it would fit so I need to figure that out.

But I wanted to know what you guys think about these two brands. I have always been a fan of the bio-wheel but I am willign to try somehting new if it is worth it. Does anybody use or know about the Penn Plax Cascade filters???

HEre are some links:

Or if you guys have other suggestions on nice oversized filters I could get for my 30 gallon let me know.

Well, I don't know why you would like to run such big filters in a smaller tank, but to each his own. Just a little help, your going to get a lot of current in your tank running those filters. It really isn't a good idea, unless you have fish that do well in high currents. Also, those filters are pretty big and will take up a lot of space.

Anyway, I would go with the penguin filter. No real reason, just preference. Tetra filters are my favorite when it comes to power filters. But, you didn't give me that option.
 
What kind of fish are in there? Some like current, others don't do so well with it. Large HOB will produce alot of current as previous post mentioned.

I use a Rena xp2 on my 29g. It filters great and not too much current.
 
Despite what people are saying, you will be alright with that much filtration with any fish other than maybe guppies and bettas. I have a Whisper 60 (300gph) and 40 (200gph) on my 30gal with tetras and angelfish. Yes there is a current but it is spread out and the fish are not stressed. Most aquarium fish come from rivers and streams and benefit from the circulation. The slightly larger filters, Whisper 60 and Penguin 350, with two returns actually create less current than a Whisper 40 or Penguin 200.

I prefer the Whispers because the filter cartridges are cheaper but I guess a bio-wheel might have its qualities. I have never used a Cascade. Some people prefer the AquaClears because they are cheap and have a large filter box. Whispers are about 3 1/2 inches thick, I'm not sure about the others. I also have a TetraTec filter on another tank but its filter box is really oversized and I don't think that the bio foam wet/dry portion is really worth all the hassle.
 
WAit, guppies don't do well in strong current? I ahve a 150GPH penguin 150B on my 10 gallon, it seems ok.

For the filter choice, definetly go penguin. Those new penguins are awesome, cascasdes are no match. Cascade might win against a whisper, but not the new penguins. Second best (or tied) would be an aquaclear.
 
I have a penguin 350 and a cascade 300 and a penguin 550 power head on my 35 gallon with my convicts.
Like others have said, over filtering doesnt exist.

:D I am also working on fixing my old canaster filter to add to the mix :D
 
Turtlefish,
If it works it works. I've just noticed before that guppies seem to avoid the current and although bettas like to swim against it, they kinda get tossed around abit. African butterfly fish are another species I've had that kept to the calm parts of a tank and did not fair well with high filtration. I personally like good circulation in my tanks and have it whenever I can. How come nobody prefers the simplicity and economics of a Whisper?
 
fiske, I use a wisper on my 10 gal and i love it to death.
easy one piece filter media, easy to rinse, but i find that they dont work as well on larger tanks. but thats just MHO use what you like i guess.
