Quick question - I'm looking to change it up from my biocube 32 to the Fluval 32. I'm wondering what success if any, people have had with 2 of the stock lights. I would entertain what seems to be everyone suggesting AI Primes, it just stinks if you buy the Fluval you are already paying for 1 light. So I'd just like to know what to expect out of 2 stock lights.
