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?

Plus, I had to remove the green water because it started to smell too.  I don't like the smell for indoors.

I have a green water tub in my airconditioned room and there's no smell, or very little of it. In fact, the clear water tank in another room is actually more smelly (in the usual aquarium tank kind of odour.) If you think about, it shouldn't smell at all if the green water is in good condition.

How often do you change the green water? I change mine once a week without fail. The longest I could stretch was 10 days. It was way too intense and starting to smell like a clear water aquarium. I have to change it and not push my luck any further.
