Due to the shape of my new corner bow (triangle), it is extremeley hard to get water flow in all areas of the tank. Anyone experienced with this type of tank? The only place that power heads will stick is on the angled pieces of glass and then the water only flows to the front of the tank, not across like I would like for it to. Also I have noticed large dead spots in the front two corners. I am running a Senn 950 return, 2 power sweep power heads, and one hagen 402. Still there are many dead spots. Also this is an odd shaped tank to try to build a reef structure in as it is very deep from front to back and once again the angled sides prevent proper building. Beautifl tank but so far it has many drawbacks as a reef. Any suggestions would be greatly appreciated.
