It is soo odd!My tank is already aerated very well!!!I even have a bubble wand airstone rena. But no good. My water parameters are good..sigh again with the water parameters..i think im gonna get sick. I'm still so sad the fact that my silver dollar died....sigh so much memories. But I'm gonna try and move on for right now. So far my brown bristlenose pleco is inside the 55 gallon tank right now..thankfully he has the ability to "gulp" the air so yeah. I want to start fresh so far, the tank's fresh!!!BUT NO GOOD OXYGEN!!!whats going on...?
