I have an old 40L 48*13*16 that I'm going to setup, and the old whisper filter has seen better days. I have a brand new Fluval 405 sitting in storage, I was going to use it for my 90 gallon but I bought a FX5. Do you think a Fluval 405 is to much filtration for my tank?

I'm keeping a small Tang community. Any help is appreciated.

Some fish prefer low current...

But for most Cichlids "too much filtration" is when the current makes the fish work to stay still even in the low current areas...

It would be difficult to have so much filtration that it causes a problem... unless you include energy use...

There's no such thing as too much filtration. There can be too much water flow though.

Amen!

Lets see.....I have two Fluval 404's and one Fluval 405 + Emperor 350 hang-on = crystal clear

Water clarity depends on the media used in filters also... Micron pads mainly.

I myself use 2 Eheim 2213's 1 on the Left and 1 on the Right side of the tank. AquaClear 5000 left side 900+gph Flow & air Across Front. MaxiJet 900 230gph right side Flow across back. Mostly breaking Surface water. All with sponge filters attached.. No issues as of yet. I clean Both eheims every 30 days but do them 2weeks apart from one another. Sand loves to eat Impellers .

One thing I have noticed with water flow is my africans get buff/thick fast when swiming in current and grow longer quicker without. My fish love the water flow.

Another amen. Of course if your fish are pinned against the glass and giving you the evil eye you may want to reconsider your choice of filtration.

And that would fall under "water flow". Hehe

there is a lever on the fluvals that you can reduce the water flow its just above the lever you disconnect the hoses from if you put it up half way it reduces flow its the black lever on top of the grey lever :fish: :fish: :fish: :fish: :fish: :fish:
