12 gallon nano cube owners: NEED HELP!

[queenangel920]

Can you please tell me how you have your nano cube set up. This tank is going to be a reef tank so I took out the bio balls and rings. I left the block sponges in the first overflow and have nothing in the next 2 sumps. My problem is the water doesn't seem to be cycling through quick enough and is stagnant. The top has a little scum and little white particles floating about. I have the powerhead turned sideways to provide flow at the top of the water and below. So the top is getting adequate flow. I started this tank a week ago with 12 pounds of live rock and 15 pounds of sand. What am I doing wrong?

you can try putting a larger pump in, but i have not had a flow problem with mine. i have the heater in the back so you dont see it and i also put some small rocks in the back in place of the bio balls to help with filtration. good luck with yours

Theres A Switch On The Pump.try Turning The Pump Higher, Might Be On Low.

Is your water level above the filter intake? If so you may need to break the surface tension of the water. Just for an experiment lower the water level to about a 1/4 " below the intake. You will notice a difference right away. If that works you may want to set a skimmer mod over the intake. (Shameless plug!!)
