Actually I didn't recommend any lighting to him. Adam is very partial to 65K lighting so I would not be surprised if his tanks have a some mix of Tropic and Actinics. I would suggest reaching out to Adam and asking him. He is super kind person and always willing to help customers even if you are not ordering something right then and there!
