I take care of saltwater tanks for a pet store , and know the basics. Just wondering what I need for my 28 gallon FOWLR tank? So far I know I need Tank -check Heater (not sure on wattage) Instant ocean-check Live sand -check Live rock (not sure on how many lbs) Powerhead (thinking maybe a koralia nano?) Any tips , suggestions , would be truly appreciated ! I also have a few more questions. Filling it up the first time should I slowly add the instant ocean and check my salinity as I go? Wanting to do clown fish , not sure whether I want to do ocellaris ? Stocking ideas would be awesome! Got 28 gallons to play around with , but want to make wise choices.
