Aquarium Cover

My tanks has been running with an open top for a while now. But because of the massive evaporation and because I just bought a Midas blenny, I'm afraid of jumpers. So, what do you guys use over your tank and what could I use that would not lower the amount of light entering the tank?

 

A clear 1/4" mesh top is the only way to go.

Putting on a type of cover which will decrease evaporation can have some bad consequences; it will cause condensation (which will impede light throughput), raise your system temperature (the amount of evaporation you have now is a means of cooling), and it will impede gas exchange (not very desirable; this will decrease O2 levels and make your pH drop).

 

Oh okay. Where could you buy this type of cover?

 

You can buy the materials here, but you have to make it yourself. There's instructional videos on the page too.
