[sheringam]

Propose brew green water in 2ft tank project

1. 23.5" x 11.5" x 13" fiveplan brand tank
2. 51.81 litres of water (13.71 gallons of water), around 12.5" depth of water
3. 2ft DIY PL lights with 2 36W OSRAM tubes and e-ballast
4. Simple sponge filter to collect goldfish poos
5. Wooden air block for aeration
6. 2 4.5" to 6" ranchus

Is it possible to brew green water in 2ft tank rather than tub? I've all the equipment with me except the PL lights which I've yet to collect from a bro who help DIY PL lights. Will switch on the PL lights non-stop for 3-4 days or until the green water turn dark green?

Let see your questions ...

YES.

Possible.

BUT ..... I shoot liao hor.

50L for 2 fish of that size ? U gotta be kidding. 1 3" fish at most. At least 50L min per fish and that's still a miserable little room to make some mistakes. Okay, it's up to you to try out. Anyway, I also using 2ft tank, but larger width, at 70L for 2 demekins. Close monitoring needed to prevent any problem faced as the water darkening.

Green water itself is already a natural filter, why add something to compete. No filter needed. Collect poo for wat ?

Wood type air block is for marine setup. Use normal ceramic or plastics type for freshwater lah.
