Tank Coverings?

[kien]

I can appreciate wanting to cover your tank for this reason but be sure to consider some ramifications. For one, covering your tank with anything non porous will trap heat and will likely cause your tank water to increase in temperature. The act of evapouration helps to cool down the tank. Secondly, depending on how high your water level is, a tank cover can tend to develop salt creep over time as water splashes onto your cover. This will reduce light transmission from your light. You will find yourself having to clean the cover often if this happens. Anyway, these may be non-issues for you but something to think about just in case

Also, there is the possible loss of Oxygen exchange with a top. More prevalent in SW tanks than FW as SW doesn't hold oxygen as well as FW.

That said, there are a lot of successfull covered tanks. Plexi is probiballly going to be the cheapest and clearest. I had 4mm glass covering one of my tanks once, and was forever cleaning it. You could see the light difference even with clean glass. Now, I just live with the evaporation. try keep tank a touch cooler? room a little warmer. That will lessen evap too

I highly recommend that you do not cover your tank with anything, unless is fine mesh to control jumping fish.

CO2 gas builds inside your tank all the time, and if it doesn't have a way to get out, it will lower your pH... which can be catastrophic. You need an open top so that the gases can exchange (ie CO2 for O2).
