notice a whole lot of bubbles on surfaces after installing MH lights

is it just me? i swear i never seen all these air bubbles before...they're everywhere, on the rocks, on the sand, even on the shrimps...doesn't seem to be causing much harm, but just strange...

The "metabolism" of your tank (things like algae and other organisms that are photosynthetic) has been kicked into a higher gear with the new lighting. Things should adjust over time.

ahh...thank you...i'm liking this MH light very much...i put 2 80mm fans in when i built the canopy and the tank is actually 2 degrees cooler now than when i had 2x65w PC...
