When it comes to aquarium filters every now and again a great idea comes along from someone who has been in the industry for a very long, long time.

The latest innovation to canister filters comes from Eheim who has a long history of having one of the best and most reliable filter designs you can buy.

Now with the Eheim Pro 4+ they very well may have just created a beast.

[Video:] In this review and unboxing Big Al’s walks through all the awesome features of the Eheim Professionel 4+ 600 Canister Filter.

Max Algae Control
The 2HR Aquarist APT Zero

Award-winning aquascapers' choice.

The smart one. Lean but powerful. APT Zero contains the full potency of APT Complete, but without nitrates and phosphates. It is specially designed for tanks with significant fish load and for hobbyists looking to replicate the renowned ADA dosing system. Its leaner dosing approach provides maximum algae control.

However, the Eheim Pro 4+ has a few great upgrades over the pro 3 that we will go over below.

Upgrade #1 – Black Is The New Black

The Eheim Pro 4 600 comes with all black equipment instead of the classic Eheim green. The black tubing and equipment hide much better which looks great in your tank.

Upgrade #2 – Xtender Control Function

Eheim describes the Xtender feature like this:

“If the media (fine filter pad) becomes blocked, the flow rate can be increased using the control function. The water will be re-directed but the biological filtration will be maintained – allowing the cleaning of the filter to be postponed for a few days.” Source Eheim
