I am just starting out with the 32.5 gal Fluval Flex Sea - stock light is the Fluval Marine 3.0 LED. Once the tank is cycled, I plan on only adding a couple fish and some "easy" beginner soft corals. If I want to try some more demanding corals in the future, will the stock like work? If I'll need to upgrade, are there options that would work with the existing tank hood? TIA!
