I've been keeping fish for close to 40 years and have been a die hard eheim fan for nearly as long. Gunter Eheim was an engineer with vision and created the first line of filters to incorporate biological, mechanical and chemical filtration in single systems.
The Pro series remain the finest filters money can buy. However the cost is steep although worth any penny. Regardless of the canister filter you own 90% of it's effectivness can be directly related to the quality of media you use. Without question eHeim's substrate pro will colonize nitrifying bacteria faster, quicker and more of it than most any media I've tried.
The material, Sintered glass has a remarkable amount of places for healthy bacteria to colonize, the shpere shape increases this amount over cermaic rins dramatically and the results are easy to see and see quickly. Lower nd fewer amonia spikes, stablized water parameters - and best of all healtheir happier fish.
Unlike most media sintered glass really doesn't break down like finished or or unfinished ceramic - nor does it loose its effecency like plastic BioBalls (great for wet dry systems - not for canister filters) Because you'll probably never have to replace these - the media pays for itself many times over as you'll get years of use out it.
A terrific media that really delivers exceptional results - your fish will thank you for it.

Something missing.
On top of the package it says THIS IS A SET DO NOT SEPARATE. Looks like something was removed from the top, does anybody know what’s missing. It’s the reason for 1 star.
