Just put 70 degree optics on my ai sol over my 30 and what a world of difference it made just in the look of the tank. I don't have spotlights anymore. Now ill compare the par levels from before and after. Stay tuned
If I wouldn't cost me 100$ to do the 90 I would have done this along time ago. I HIGHLY recommend this to all ai owners out there. My zoas that wernt opening all the way have already started to show signs of opening up more. Before I checked par I would get 300 and 2 inches in either direction would get 200-260 can't wait to check par levels tomorrow or Sunday when I get the par meter back.
