I was wondering if anyone else runs glass covers on their reef aquarium?
I do, I purchased custom cut Starphire glass covers for my reef aquarium.
There are so many advantages from my observations:
1) Lower humidity in the house. I run my air conditioner less. I don't have to pull out as much water from the air to keep it comfortable, especially on days where the air conditioner does not run very often. I was able to raise my thermostat 1 degree and felt no rise of humidity inside the house.
2) I use less reverse osmosis water, due to less evaporation from the aquarium, saves me money on the water bill.
3) Much less salt corrosion on lights and other items exposed to salt water, my Radions collect much less dust.
The only disadvantages I have observed:
1) Higher aquarium temperature, I see about a 1 degree increase, due to less evaporation.
2) Less light entering the aquarium due to reflection from the glass covers, I had to increase my Radions percentage higher.
I am getting great growth, even with the covers, so I think it is an overall win.
