Who uses the Vortech foam guards for the MP10/40/60's? I have been using them on my MP10 for years and I'm thinking of ditching them because they clog up quickly but I also sort of like them because they offer a bit of mechanical filtration by removing detritus and particles suspended in the water. Only issue is when they clog up they flow drops very quickly. I seem to have to change them out a few times a week which is starting to be sort of annoying... I originally got them because I had a fish get sucked up but all my fish now would be fine...
