Filtration overkill!?!?
So when im transforming my 45 gallon tank to a SW i wont need my emperor 400 so im going to put it on my 55.

my 55 already has a emperor 400 on it

Would 800 GpH Be To much overkill? i have Sword tails and 2 angel fish. 3 guppies and 1 bristle nose pleco

I already have one UV Filter in the Tank. thinking about getting a second.

so its going to be

x2 Emperor 400 = 800GPH
and x2 UV Filters

I'm thinking it would be way overkill. I mean, turning the entire tank over ten times an hour would be a lot, but that is still only 450 gph. You're talking almost twice that.

There's no problem with over filtration, but your fish may feel like they're in a whirlpool!! And you don't have that many fish....

Just curious, why are you getting a second UV filter?

for my other tank. and the one i have isnt doing to great. its for a 40 gallon. so i need to get another.

Filtration, not much. Currents, yes unless you can divert it to avoid the fish being swept around.

I think i might build lips for the Output flow. so it hits and creates an eddie and goes to the sides instead of going straight to the front of the tank and then down and sideways. Any one like that idea?

i dont think you can over filter your water can you? The lips idea i think is really good. You could also try adding a sponge to the intake of ur filters so it slows the intake, thus decreasing the output.

Im going to put an emporer 400 on my 40 gallon

As was stated earlier, you can't overfilter from a Biological or mechanical filter perspective, but at some point it's overkill and perhaps a waste of money and electricity. It's the current that important here. Most fish like some amount of current and plants need some too. But if the fish are swept around too much, you have to think they will get tired and perhaps, stressed.

Wisfish makes a good point. Fish like angelfish, gourami's, severums, and Discus would not appreciate too much current while Barbs, danios,and some of the tetras would probably be more suited to strong current.

For what you've got in the tank the single Emperor is probably overkill. Adding the second won't really benefit you in any way. I'd just store the extra filter for another tank later or sell it.
