evilbuy sponge filter(2ish $) + power head(4ish $). cut and superglued together. total costs 7$. works like a charm. i made this because i couldnt find such a product in LFS nor in webshops. air powered sponge filter didnt suite me because of bubble noise and current absence.
sorry for picture quality, it was taken with a potato.
