Was reading on what would be best for my reef and can't decide on the best course, currently have a glass top over the DT with the sump open with a mesh as the air conditioner is constantly throwing kitty hairs into my tank up top. So the question is should I stick with the glass top with the usual weekly cleaning for salt creep, swap to a mesh top so more light penetrates, or go lidless (prob not the best option though). The glass definitely cuts back on the evaporation and helps with heat loss since I keep the house at 71/72F and the reef is kept at 76/77F.
