[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?

after 3 attempts, finally succeed in brewing green water. i know algae boom after seeing algae spots on sides and bottom of the tank.

water stinks cos of high ammonia level and decomposed particles. ranchu breathing heavily near the surface of water and seems to be trying to jump out of the water. so i transfer it back into the big tank and switch on PL lights for 12hrs. next morning water turn green.

After work on the same day, i cleaned up the algae spots and change 65-70% of water. again i switch on the PL lights for 24hrs this time, water turn virgin green and does not stinks.

Tested PH level around 8.0, almost the same as the big tank and transfer the 4" ranchu into green water tank. Did the same, switch on PL lights for 12hrs.

Second and third day after transfer the ranchu, green water turned darker green each day. Four day it's so dark that i can't even see it unless it's swimming towards the sides of the tank.

Feed it with lots of pellets and switch on PL lights for 12hrs after that. This is the seventh day, green water doesn't stinks although it's very dark green in colour. Ranchu not breathing heavily anymore. Going to change 90% of water next time.
