HElp,,, Been trying ou the DIY CO2 but everytime finish very fast. Thus I decided to increase the amount of sugar to 500g and just add 1/2 a teaaspoon of yeast. Wow. the effect is good. just a normal 500ml bottle lasted me 2 weeks. but now here come the bad point is that my fishes looked as if they are drunk... normally they are very lifely and would come to the surface to eat when there is food. now they just swim very slow and did not even eat the food. i decide to change the CO2, Yucks. the smell is like a beer... did i left my CO2 for too long???
What can i do to help my fishes???
Thanks
