Thanks! We should update the FTS pics. Now it looks even better :-)
As filtration there is filter floss on top of chamber 2, sitting on some egg crate, then live rock rubble. I used to have a fuge with some cheato in chamber 2, but the submersible light failed 2 times. So now the cheato is into the display area.
In chamber 2 there is also the input and output of a Remora nano skimmer hob.
In chamber 3, where there was the blu sponge I run a bag of chemi pure elite.
The rest of the filtration is the huge amount of LR in the display.
The return pump was upgraded to a Maxy-Jet 900.
