For those of you using a high tech tank, do you guys have glass top on your tank? Or do you leave it open?
I keep mine open top
I have my 20 gallon long high tank. At the moment, I took off the top. Should I keep it that way or should I put it back on?
Do you value fish/shrimp lives? If so, keep it on. If you don't mind loosing a couple every now and then, keep it off.
Do you enjoy cleaning glass? If yuo do, leave it on and clean regularly. If you don't like cleaning glass, keep the top off.
Does the cover make any difference in keeping CO2 that I am pumping into the air?
No, no measurable difference.
