Hey folks - so I am finally moving my tank over from a IM 40 AIO to a Neptunian Cube M120 - which is a 4'. On the IM 40 AIO I had a Hydra 26 - so now with this new tank is a 4' I would need something better. So would I be best to get another Hydra 26 or are there other options I should look at for the tank. And is it suggested to have 3 lights or 2 lights. Tank will consist of a mixed reef environment of corals and fishes. Any feedback would greatly be appreciated! Thank you!
