That’s why the sponge helped. I got a sponge on Amazon for cheap similar to what is on a sponge filter and it covers the intake. Traps all the leaves and crap.The problem is that my hob filter intake gets clogged. On the outside. So I need to pick it off the intake filter, which isn't a major problem, but I'd rather it not.
When it gets on the sponge it no longer clogs the filter itself, and it’s easier to get off (take out during wc and brush off).But all the leaves and crap is the thing that is clogging it.
