Autodosing ferts in return line feed from filter??
I currently use the water pump method of autodosing my ferts(wasserpests). Timer kicks on the pump, pump pushes ferts from a container up, drops it into the tank.
What I want to know is if I can just put it in line with my filters return hose. I just redid my plumbing using 3/4" PVC instead of the normal flex hose. So, I thought, why could I not just do the same thing that I do with my CO2 reactor(rex style). Just insert the hose/fitting into a section of the PVC return, with a check valve. Timer kicks on the pump, ferts pushed into the return feed.
Anyone have this going? Will it work? Thought it may be easier/more streamlined.
Thanks for the responses.
