Conclusion
Choosing the right replacement pads and cartridges for EHEIM Ecco Pro, Pro 3/Ultra G and professionel 4+ means matching media type to each stage: coarse pre-filter to protect, fine fleece for mechanical polishing, carbon for chemical problems, and porous biological media to cultivate nitrifying bacteria. OEM media guarantee fit and documented dimensions; aftermarket kits can be cost-effective and convenient as long as you confirm tray geometry and follow replacement intervals—mechanical pads more often, carbon after medication, and biological media only when performance falls. Regular checks and timely media changes preserve flow, reduce maintenance time, and keep water healthy.
