[quote=eu71my;49534]I am not sure i got carpet algea. It just look like dirty green at the bottom of tub. i got them after 2nd week of water change. My balcony don't get direct sunlight. It just very bright during the day.

For feeding, do you defrost the BW ? I will try you method. Today i found the fish is bigger and can swallow the BW eaisier.

No defrost, I cut it while it is hard as ice..then put it floating in the water.
Does anyone know of water plant hormone? Where can ge them? I'm thinking to try to use it if it's avaiable. But only on my spare tank.

Cheers,
