Recommended internal filter for 70 liter tank

Hi all. I need to know the recommended internal/powerhead filter for my 70 liter
tank. I current have a aquaclear 200 in my tank with a 700 l/h resun internal
Filter. I want to replace it with the new recommended one. I just need a sufficient water flow current
In my tank. I think the 700l/ph filter is to heavy for my tank.

Please help

 

You could try the cascade 600. Still have a cascade internal filter and it's still running strong and 100%. Also should come with different "nozzles" to adjust water flow.
Look on the 600 - the blue sprayer at the top is for maximum water flow.
Look at the black filter - the spray bar is too minimize the water flow.

 

Take a look at the Dophin F800, using it on my 60L, nice little filter.

 

Hi All, need to make a correction I dont want to replace the aquaclear I just need a new smaller internal filter with less water flow. Maybe I might go with the smaller Cascade 400.

 

You could also try a HOB filter if you want less flow. They take way less space than an internal therefore giving you more scaping space, aswell as making your tank look better. If you want some water flow it is easy to make a DIY flow thingy from the hob outlet.
