ok the tank is now a reality

for a low waterflow I used a 156 GPH powerhead from teh main tank and ran it up and over to the higher 20G long. The disperal for the incomming water is a 24 inch capped off 3/4 inch PVC pipe with holes drilled aprox every 1.5 inches to spread out the water flow so its not too powerful in any one area. Its got a 200 GPH overhang overflow returning to the main tank. Needs more live rock yet though.
