filtration sys:
Fuval FX6 to return to Side IOUS (for mech , and CR in trays)
then return to side sump , 5kg SC matrix. abig pack of bio balls, 1x DIY 11w UV (24/7), 2 packs of Active carbon to clear smell 2~3 weeks change.

thats all i use no added chemical my water v clear . once a bit cloudy , thats where my wool in FX6 need to change lor. abt 3 weeks time.

so far my water v clear. good for my aro, tig and ray

anything i will add salt diluted water solution and on heater if there is a need.

water clear doesnt mean good if u added too much additives.
