Above tank sump
I am setting up an above tank sump with plants in it, and have been trying various methods to move the water. My problem is matching the inflow/outflow. It occurred to me that using something to suck the water through would create better control. Any ideas how this could be performed? I have several submersible water pumps of varying strengths, but I need them to pull the water through the sump. There must be something that does this, but I am having no luck... don't know the right terms?
I have one that pumps the water up into the sump, but getting it to flow out through hoses at a good rate is a fine balancing act.
Any help would be appreciated!!
