Nice little solution. I installed a Hydor Koralia Nano (240gph) for about $28 pointed right where the dosing lines dump into the sump. Just enough flow to avert precipitation (dosing pump timing conveniently kicked on the soda ash right adter my install) but not too much to stir up that part on the sump. And, probably the cheapest fix ever on my tank! Thought I'd share because a week ago I was looking for ideas and did not see this precise solution. Coincidentally got the same pump for my 8-yr-old daughter's 20g freshwater hex tank (perfect for low-tank flow) and eureka!
