nice nice!!!
good luck with ur co2 issue!
if theres anyway to reduce surface water agitation that would help u keep the co2 in,
i have hangons on my 75 which creates alot of surface agitation,
so i siliconed pieces of the plastic i cut off from the glass lid on to the parts where the water runs down and yay !!!!! its not to bad, also all types of algea grow on the plastics being so close to the light it adds on to my bb!!!!!!!!
