i am going to purchase a fx5 fiter for my 215 liter tank[soon to be upgraded] and currently have 2 large oscars ,1 large convict, 1 large jack demesy and 1 medium blue zebra malawi i currently have a tetratecex1200 and it works well however the oscars are really messy SHOULD I DO IT

The Fluval FX5 is a fantastic filter! I have always been an Eheim kinda girl but since keeping large fish I decided to give the Fluval a go. I have yet to be disappointed and highly recommend it.

However, your tank is far to small for this filter. The FX5 filters more than 600G of water per hour! The force of water that comes out of the outtake is amazing and would cause way to much turbulance in your small tank.

I assume you mean 112 gallons, an FX5 might be overkill for 112 litres plus you couldn't keep the fish you mentioned in a 112 litre. Lets say it is 112 gallon, the FX5 is an excellent filter for tanks with messy fish, i know three fishkeepers with these filters and they reckon they're more than suitable.
With your tank, assuming (112 gal) you might want to add a 405 as well just to keep the turnover healthy.

I have 2 running, No problems and highly recommended. If you don't go for one of them the Ethiem pro's are as good. I was going to say the filter will be as large as your tank if it is 112L but the others have picked up on this too so I won't bore you. )

i got my current tank for free and might upgrade soon ,il post a pic to show you guys my situation .im gonna upgrade soon so its ok.the oscar and tankmates are fine in the current tank so there is nothing to worry about

is it 112 gal or 112L?

it is 120 centimeters lenght by 42 centimeters width and 42 centimeters heght

wich is 47.2 inches by 16.7 width and 16.7 height

forget the filter get a tank. thats what I would do.

i make that about 215 L, or 57 US gallons

T

ya i got the tank for free and it will be upgraded soon .the fx5 is on specail and i am gonna buy it .and thankx for the size info

Had my FX5 for a year. Great filter BUT cleaning it is a pain. You can't clean it unless you empty it (impeller is at the bottom) and it holds a hell of a lot of water. It's also very big, I have to have mine standing next to the tank, not underneath it. It does provide excellent filtration and flow rate and it's pretty quiet when set up properly (on the level with no air in it)
