Changing a filter

[Li-er]

Having seen the Nexus 300 i would like to swop one out for my CL3 what is involved is it just a case of replumbing ?

Is your filter a gravity or pump fed system? How big is it's footprint E.G. height, width, depth.

Hi li-er
for what it is worth i would convert the cl3 to k1,there are some really good threads on this just do a search,
i think with three buys of k1 leaving one as a vortex you will achieve some good parimeters even on your size pond.
It realy is not that hard to convert plus its a LOT CHEAPER
The reason i say this is i have converted a cl1 to take k1,the results on this are fantastic,all be it on my QT tank (300gal)
any way good luck what ever route you go
