Review on 🔍 High-Quality Replacement Filter Pads (16PCS) for SUNSUN/GRECH/SUPER/HW-302 CF300 Aquarium Filters by Sharon Prasad

I have a Sunsun 304b filter and I don't even think there are OEM filter pads from what I see online. This is the second time I've bought most of them (from an auction). They are thinner and less dense than my first purchase. This of course limits the filter options. So I double the fine filter I used in the last compartment. I didn't calculate whether the first purchase was more profitable because I'm lazy. It's also too much trouble to return it, so I just use it. Since then I've only cleaned the filter once and rinsed it in tank water (to keep the good bacteria in it) and it seems to hold up to light push-ups, but don't expect it to hold up to many push-ups. I rate it neutral.
