I have a fairly old 75 gal and an 80 gal that both have glass center support approx. eight to ten inches wide,and also take the versa top glass cover's.
Can't say the glass tops hamper my low tech affairs much at all ,but have noted that the plant's growing directly under the center support's for the tanks which have become hazy due to age,condnesation, grow a bit slower due to the hazy condition of the glass center support's (Ludwigia repen's, crypt balansae,and watersprite).
I chose to remove the versa tops,and I hung my quad T5 fixture seven to nine inches above the surface of the water which gives me a bit more PAR without pushing the CO2 requirement's of the largely slow growing plant's in the tank(s) with the exception of the Ludwigia.
I used to clean the glass tops each week ,to help keep them from becoming hazy looking like the center support's but removed these tops some month's ago cause I got tired of cleaning the glass tops of three or four tanks.
