Hello everybody. I'm a little new to saltwater aquariums. I currently am setting up a 150 gallon tank. I so far only have a zebra moray eel and a scorpian fish. I plan to move the scorpian fish into another tank so it wont eat the new fish. I am interested in making a planted tank. I was wondering what I need to do to sustain one (like co2 injections, supplements, etc.) I will be using 2x160 watt vho. Is that enough lighting? I will be keeping no corals. I heard that some species of macro algae release toxins when cut, are they harmful to fish? If anyone in Hawaii knows where I can buy coral please tell me, reef tank is second choice. Any help will be appreciated.
