I need a little help on finding a good hood and lighting system or light bulbs for a 10 gallon for some mushrooms or other easy care soft corals, what corals do you recommend and what is a good lighting system? I definitely want a yellow Clown goby. Is that all I can have? People say Clownfish need 10 gallons for a pair but I thought it was like 20 gallons? Side question: Is distilled water ok for mixing salt with and topping off the evaporated water? I don't have an RO unit. Thanks everyone! :;hi1 I'm new so, kinda gettin' used to it here.
