I am having a problem with maintaining flow from my twin return pumps. this is an issue because the water level of my sump changes ...which changes my auto top off's accuracy. I currently have a 120 gallon reef ready tank that uses 2 durso drains and 2 returns. I wonder if it would be better to get one pump that is variable speed and if an apex or other controller could maintain the water level for me with the help of a float switch in the main display?
