FX4 for 55g? Overkill?

[Mercfh]

I am wanting to upgrade my canister. I thought about an fx2 but the fx4 isn't much different in price. I do worry about the flow however. Which would you choose?

I also heard the FX4+ have a valve on the bottom that is prone to leaks?

I use an fx2 in a 75g. It's a bit strong for me because it's an angel tank, primarily. I think it all depends on what you want in it. and how big of a waste producer they are. You can always throttle down the output side of the cannister. Builds up the same kind of pressure that a clogged filter does. And the motors are designed to handle that kind of load, mostly

Yeah I figure since it was actually on sale cheaper than the fx-2 i might as well just get it and can throttle it down some if needed.

Absolutely. And you never know when you may need a bigger tank. 😉

Might I suggest a sump? I run a 20g sump on my 50g super easy super simple.

 

Whenever a bigger canister filter conversation comes up I jump at the bit to promote sumps so excuse me. 
 

20g high with a 12g fill, which means in power outtage-ive had 2- I have 8g of overflow. Never needed more than 5-6. Refugium style with shrimp to help keep things tidy down below
