Quality Hang On Back Filters?

Hey guys. I've been running a marineland emperor biowheel filter on my 75 gallon tank recently along side a fluval u4, but I've noticed my bio wheel constantly slows itself to a putter, nearly every 3 days. the bio wheels on my 37 gallon and 10 gallon never do this, just the emperor. It's getting really annoying to tear it apart to trouble shoot (only to find absolutely nothing is wrong with it to my knowing) whenever I set it back up and plug it back in, it seems to have a decent flow rate again, though oddly enough not nearly as much as the smaller one on my 37 gallon tank.

I'm thinking of trashing it and just cutting up the wheels to keep the bacteria, and getting a new system running.

The ones I've been looking are the fluval c series filters and the hagen aqua clear filters, though I know nothing about either of them, they seem like they've got pretty good biological filtration to them once established. And I'm getting rather sick of buying marinelands right fit filterpads or whatever to have to cut them open with a box cutter to get all the crappy carbon out of them.

these are the only other two filters I know of (aside from petsmarts crappy line of filters which have no real way to preserve beneficial bacteria and those aqueon ones which seem pretty bad in general) and I'm kinda wanting to see what else is out there for me.

On another note, I'm also very interested in making use of seachem purigen instead of carbon, so I'd like a filter with a nice place to store the purigen packs.

Are there any other filters out there aside from the ones mentioned? Do you guys have any views on the fluval and hagen filters?

P.S. I'm not interested in another internal or a canister filter. I'm happy with just getting another hang on back, they're cheap and pretty efficient, at that.
 
Running a Fluval C4 on a 36 gal tank ... does move some water ... and does have spaces for additional filtration "packages" ... almost like a HOB canister ... the aqua clear filters (remember Fulval is a Hagen brand, the C series is the "top of the line") work well too (and have the capability of inserting, and staggering replacement of different filtration "packages", I have one with my 12 gal Edge - less pricey than the C series.
 
Do you have sand substrate in the tank that's running the Emperor filter?
 
Go with the Aqua Clear. They are one of the few filters I haven't been able to kill, though I haven't tried feeding them sand yet.

:lol:

My 20 gallon sand tank has a Penguin 100 & a Topfin 20 on it and those cartridges get sandy pretty quickly. Both motors make more noise than my other tanks too, I guess because the sand is getting in there and creating friction?
 
Sand will tear up impellers, shafts & bushings. A piece of sponge on the intake will help minimize this.
 
Now he tells me.......... :rolleyes:

No really, experience is the best teacher, just not the cheapest.

Thanks for the sponge solution, I'll have to try that.
 
I have sponges on most my tanks that run the marinelands and havent had many problems. But Tolak is right about the aquaclears...i have replaced marinelands alot sooner and my original aquas are still going strong.
 
My Emp 400 has been running great for over a decade. The current ones are crap however. Have you used a brush to clean out the U shaped grooves the wheel pegs sit in as well as the wheel pegs themselves? Have you removed the spray bars and reamed them out with a brush as well?

While that emperor was set up in early Feb. 2001, I also have about 25 Aquaclears running today as well. They also were made better years back.

Cheapest source for AquaClears I know is http://www.kensfish.com/ he has them on special- you have to put them into the cart to see the price.
