aquamedic vs. tek light

[JPotter]

I have a new wave 4x24 T5 fixture. You do need to mount it above the tank or put a shield over your tank..the latter reduces H2o evaporation but tank heats faster.Initially I had no shield and had them close to the tank..did not work well as got condensation under the reflectors. There are fans in the fixture which help reduce heat build up. I now have mounted them about 6" above the tank and they are working very well. I put in 4 different color ranges and corals and clams seem happy so far. An ATO system deals with any evaporation.
