I upgraded my mag 18 to a mag 24 and even though it comes with a gaurd its only to protect from big things like decent sized rocks or particulate and does not offer much protection for the smaller stuff. I DO have a "cut to size" filter floss over my drip tray and that collects a lot of the smaller stuff but I do see some stuff make it through. Do you guys have any suggestions on what I could do/use to protect the pump without dorking the flow rate?
