Multiple Hang On Backs For 55 Gallon??

Hello folks-

I've had a 29 gallon tank going with a Marineland Penguin 200 (rated for 30 to 50 gallons) for just over a year. I really like the filter, so was planning to go with the larger version (Penguin 350, rated for 50-75 gallons) for the 55 gallon I am just now setting up.

But the thought occurred to me that it might actually be more efficient to use multiple filters for the 55 gallon, possibly two 200's on each end. Or possibly the 350 with a 200 on the other end. I just don't see how having any filter on one end of such a long tank would be practical or effective.

What are your thoughts? Has anyone done this?

Before you suggest it, for a variety of reasons I am not planning to use a canister filter at this time. I use the customizable inserts in the HOB filters, so I can get real creative with my media. Plus I like the aeration the HOB's provide, and even the sound.

 

I have 2 filters on my main display tank ( its overfiltered ) but I do this in case one goes out ( one of the filters has been in use for 7 years, the other about 4 years )
AND having 2 gives me the opportunity to, "Seed" extra filter pads in case I need it for my other tanks, etc

I also have 2 heaters in this same tank

 

Yeah, part of the reason I want to continue the Penguin series (although this is a very short term reason) is I am going to use dirty filters from the 29 gallon to help jump-start the cycle on the 55 gallon when I get it going.

 

I have two HOB filters on many of my tanks. I prefer having two filters running for many reasons. Most importantly for the reasons Junne mentioned. The only tanks that don't have 2 filters are 20 gallons or less.

 

I run 2 HOB's plus 2 double sponge sponge filters for my 55. I don't believe it is possible to over filter an aquarium.

 

I don't believe it is possible to over filter an aquarium.

The only time it can pose an issue is if there ends up being too much current for the fish. As long as that isn't the case, you can never over filter in my opinion!!
