Hi, I’m looking to start a saltwater aquarium. The size I’m thinking to get is a 75 gallon tank. I really wanna have a starfish but I’ve read that you should have a tank for some time first so they have food. So I’m thinking of getting a strewberey dottyback 3in, red scooter bleny 3in, clownfish 5in, 2 cardinals 8in, green chromis 2in, and medium green mandarin goby 4in. Is 75 gallons enough space? I also wanna have corals. I was thinking pulsing Xenia coral, green star polyps, magician zoanthids, Skyrim zoa & dragon eye zoanthids. Can I also get and alps corals ? I was thinking to get a power head & Aqueon quiet flow 75 power filter. I was going to use Carib-sea alive Hawaiian black gravel. I was thinking a 300w heater but should I get multiple heaters and put them on either end of the tank ? What watt lights would you suggest for the tank? I was thinking of getting 2 NICREW 175w led reef lights. How much salt will I need for a 75 gallon tank? Should I use the Pacific Ocean water from pet I or can I just use tap ? Or brita filtered tap? What other additives do I need ? Conditioner ? Calcium ? Sorry for so many questions ! Thank you
