Salt Water Premix Resevoir
i've been trying to keep a 30 gallon tank full of about 15 gallons of premixed saltwater. i have a powerhead in there and a heater. the only problem is that above the water level, it's getting a bit mouldy. do you think contact with the mould would be dangerous to my reef?
what method do you guys use to keep quantities of saltwater on hand?
