No the sponges are the only bio on my filtration.
No, Michael Böttner here in Germany has a bigger Tank perfectly running with HMF in the corners.
The NEWA9.7 has been in the tank with the Aimara, the ECM42 is an recent addition and make best work on linear watermoving. No low oxygen corners and all of the ''dirt'' is moving into the middle of the tank so i can easy vacuum it. I Love it!![]()
