Okay, I have a spare 10 gallon tank with a 30 gallon filter on it, and I want to make it a refuge for my 29 gallon reef. This would increase my total vol. to 39 gallon, and add another 30 gal. of filtration. But I have no clue how to plumb it. If anyone could give me detailed intructions on how to do this, I would greatly appreciate it. Also info on where to put it would be appreciated.
