水草情迷

Has anyone seen this reactor?
I've used it for 3 days and killed 5 fish. Co2 too high!!!
Every little bubble disolves in the water. Dame good, but kills fish. Have to inject air to keep my discus alive.

Where did you buy it? and How much? It sounds ok.

Got it in Guangzhou a few weeks ago for 15 RMB. With a 2kg co2 tank as well for 95RMB.
The blue thing in the cup spins and mix the water with the co2 and 2 small holes on the bottom let the water back out. My co2 indicator is YELLOW which means co2 pass beyond testing point.
I am changing the config. so more O2 can be mix in the water, I need my fish to live too!!!
