i ran a 20g long refugium, on my 225 gallon tank and had no problems. nitrates and phos were 0. how do you plan setting on setting it up and what are you planning on having in tank.
im building a reef tank with few fish. wanna be able to have as much as different types of creatures i can. im still doing research of how to set it up. prob the basic sump with a refugium. was told though that might not be enough room for a refugium in a normal 29gtank. planning to do it myself. do you have any suggestions?
