My two scrubbers (55gal. ats on the left and 30gal. ats on the right) are both using the recommended 120watt eq. R40 flood lamps. I am getting a lot of evaporation in both tanks. I was wanting to change to a different type bulb so it would be easier to enclose the ATSs to cut down on evaporation. Could anyone recommend a bulb type and a place I might be able to purchase them on line? Thanks for all your help!!
