Forgotten Path

Sorry for my non-responsiveness, I went on vacation shortly after posting...

Currently I am trying it without the glass canopy (on the legs), and the evaporation doesn't seem to bad, maybe an inch a week at room temperature...

Zapins, I'm not sure that my two T5's will get hot enough for evaporation to clear the glass... Of course, I'm not sure if I've ever had it on long enough to find out... If the evaporation is too much of a pain, I will go with that approach, and hope it does get warm enough (or warm enough fast enough not to cut in on a lot of light time). I'm going to stick with the above approach for now, since I like the idea of emergent growth, and since bosmahe1 has never had any problems using his fixture in this manner. I will keep in mind the cleaning techniques for my other tanks, especially my African clawed frog tank, since it has a ton of hard water build-up. Thanks!

Thanks to everyone for their input!!
