Thanks for all the comments.
The filtration system is very simple, consists of mechanical filtration, biological filtration, and chemical stage.
Mechanical filtration
- 3D setup, layered. Capturing particles in stages by size, from big to small.
- Cleaning the medias every two to three days, depend on the type of feeds.
- Changing the medias weekly.
- Add Biozym during every cleaning to maintain nitrification capacity.
Biological filtration
- First compartment, nitrification. Momotaro Bacteria House, submerged, cross arrangement to enable turbulence flow.
- Second compartment, nitrification. Mr. Aqua CR in netting, loosely pack to allow flexibility in arrangement.
- Third compartment, nitrification and denitrification. Biohome+ in netting, loosely pack to allow flexibility in arrangement.
- Fourth compartment, pump with aeration.
Chemical stage (Not allow to share the details as of now)
- Flow from one of the pump.
- Remove NO3 and tiny particles.
- Flow return back to pump compartment, drinkable quality.
Others
- Feeding once a day. All kinds of feeder, pellets, MP.
- Maintaining pH at 7 using sodium bicarbonate. No CC or OS.
- Using WIZZ fast cycle to reduce the load on biological filtration.
- Water change of 50 to 60% weekly. On and off twice per week. Using seachem safe and add Biozym and WIZZ fast cycle every water change.
Keeping fish is fun, is combination of science and art.
