I also had somewhat of a bigger tank and downsized to a 56 gallon DT about 4 + years ago. I do still have a 30 gallon fuge and 20 gallon sump hooked up to it but this smaller tank is perfect and I am not wanting the work or expense of a bigger system anymore. The smaller tank is home to 16 fish and I am content with that. I do have a lot of rock to give those fish adequate territory space and I do feed heavily to keep 'hangry' behaviors at a mimimal.My sentiments but I have had a 300 gallon display. Going smaller to much time and expense for the bigger displays. Use to think I wanted 500- 1000 gallon display now I am going to be happy with a 65 gallon display smallest saltwater tank I will have owned
