Fluval 404 with 4 compartments of cheramics. At the bottom Hagen Biomax, then Ehifi mech and lastly two compartments of Ehfi substrate.
When not photographing I ususally have a Hagen powerhead with a Quickfilter for polishing the water and a Eheim surface extractor to polish the surface. I feed the intake with CO2.
