I was given an 80 gallon tank the other day with a sump / refugium in the cabinet below.
Nearly everything is ready to set it up but im not shure what to put in the sump. Ive been reading about Kaldnes and have a very nice fellow in Vancouver that is going to be sending some out to me. From what Ive read, Kaldnes is nearly all I would ever need. Is there anyone out there with more experience on the topic?
Ive got one of those closed up corner units in the main tank with the holes drilled through the bottom of the tank. There are some glass shelves in that peice and am wondering if Bio Balls would be good to put into there as well?
Any more hints and tips would be greatly appreciated.
Thank you kindly
David
