Saltwater fish tanks

At one point we had 4 Salt water tanks running. A little 1/2 gallon thing with a cow fish, a 40 gallon reef tank that had live rock, some coral and a few fish, a 125 bottom drilled fish tank and a 300 gallon sump tank. I kept the 300 gallon tank. Would strongly suggest staying away from a bottom drilled salt water tank. They have the plastic grates on the bottom that act as the bio filter. What a pain in the ***. Had to take it apart every 8 months or so to clean under the grates other wise the tank would stay funky looking. The 300 gallon tank had two sumps in the back of the tank these were filled with bio balls. You could read thru 8 foot of water. I never did a live rock tank/coral tank, other than the small reef tank. The swim tanks were easy to cycle and the variety of fish was incredible. Will try to put more pictures up later on......
