The polishing unit fits perfectly into my 400G filter. After installing it, the water clarity improved noticeably. Easy to install and no leaks were observed during use. Works well with regular filter maintenance.

I used this unit with my 300G filter and found it helps keep the water clean. It’s a simple addition that makes a difference in the filter performance. Slight improvement in flow rate after a few weeks.

Great replacement part. Fits without any issues. The polishing action helps reduce cloudiness in the water. I’ve used it for over two months and it still performs well.
