I am new to the Saltwater world so this may be a dumb question. I was at petco the other day and found a brand new 12lb bucket of Fiji Refugium Starter mud for $5 (usually $80). I also had a $15 walmart gift card so I bought another 10 gallon tank. Can I use a tank the same size as the display tank for a refugium? I know that 10% is kind of the minimum and most people keep a refugium around 50% of the size of the display tank but can I do one that is the same size? I would guess with the 10 gallon tank I would have around 5 gallons or so of water do to the space needed for flow? Does this make sense?
