So, my water is constantly cloudy. I have a diamond spot goby who is always sifting the sand and that is where the particulate matter comes from. I was just hoping to get some recommendations on where to position my power heads to get the best "push" to move water towards the overflow box. Right now, I have the power heads running on opposing pulses so the water column shifts back and forth. Between that and the dual returns, I am not having any luck figuring this out. Would it be better to mount the pumps on the back wal and have them blow towards the front? Would the push and pull more towards the overflow? How are you setting up your pumps to churn and return?
