EHEIM ecco pro 300

Each filter has three roles in a planted aquarium. In order of importance:

NITRIFICATION
It is the most important! Toxic and algae-causing ammonia in the aquarium must be decomposed. As fast as possible. Billions of bacteria growing in the filter convert ammonia into nitrite and then nitrate.

WATER CIRCULATION
Nutrients (plant food and CO2) must reach the plants. Solid decomposition products should be kept afloat. Good performance is essential.

WATER TREATMENT
Solid decomposition products must be physically removed from the aquarium and decomposed in a filter or removed during cleaning.

For a filter to fully perform all three roles, it must meet several criteria. Ideally suitable to have a bucket of the right size to store the right amount of filter media. The filter material contained in it must be of adequate quality and variety. The pump in the filter must have sufficient capacity. The filter should be easy to clean so that the cumbersome process does not deter the aquarist from regular maintenance. Plus, the filter needs to be reliable; no one wants to flood a living room or office due to a cracked tap or joint.
