Brew Green Water In A 2ft Tank Options

[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?

i'm not using any filter, only an air stone with 2 x 36W 6000K OSRAM PL lights.

PL lights are more than 10cm away from surface of water. Now reduce to 2~3 cm.

Added 2 spoons of salt in the previous setup. Is that another mistake?

Had drained all the water from the tank and added fresh water without the salt. Not to forget Genesis anti-chlorine which removes chlorine and chloramine as well.

Yes there's too much dissolved organic particles in the water and particles at the bottom of the tank. have might be feeding too much green peas to goldfish.

Added half spoon of sodium carbonate to buffer the KH of the fresh water.

no choice have to use a 2ft tank instead of a tub cos of space constraint.

still learning how to brew green water in a 2ft tank.

so far so good. few more things

1. fish size (body length, and type)
2. fish load (number of fish)
3. food (how frequent, what type)
4. photo period (how long)

what else u add that you did not mention ?
