EHEIM has several versions of the Professionel 4+ currently available on the market. So, what are the major differences between the 250, 250T, 350, 350T and 600 models?
You can find out in this comparison guide between these canister filters.
Quick Summary
The EHEIM Professionel 4+ 600 offers the most volume, the greatest number of media baskets and the fastest pump performance out of this group. So, if you have an aquarium that can hold at least 60 gallons, then the 600 is the easily best out of all the available models.
For aquariums that are less than 60 gallons, we recommend picking up the 350 or 350T over the 250 or 250T. This is because the 350 versions have more volume, number of media baskets and faster pump than the 250 versions.
The 250T and 350T are the only two filters in this comparison that come with a built-in heater.
