I have recently added some Guppies to my high tech tank by the end of the day all the Guppies are at the surface… no other fish seem to have a problem. Have anyone else had any experience of having Guppies while injecting CO2?
This means either (or both) two things. You are injecting more CO2 than your fish can cope with or your water is not oxygenated enough.I have recently added some Guppies to my high tech tank by the end of the day all the Guppies are at the surface
Drops checkers can be backstabbers and I wouldn't rely on that to know if you have too little or too much CO2. What I would do first and formost is to improve water oxygenetation. Do you have a skimmer? Is surface water properly agitated? If no, then solve that. If that doesn't solve the issue start reducing your CO2 ever so slightly until your fish don't swim to the surface.its very odd green drop checker though and nothing has died
