Replacement Filter Pads fits SUNSUN/GRECH/AQUATOP HW-303B CF400 Aquarium Filters (12 Fine + 4 Coarse) (12 Fine + 4 Coarse)

ok

These seemed to be slightly thicker than the original ones that came with the canister. They fit tight without gaps along the tray. Big fan of having extra filters around for my fish.

Perfect for filtering and good quality.

Call quality and I can buy them in bulk

This product is of good quality. With this seller the deliveries are fast.

if this came in a large size i would go for that, im a little bigger than average and its not quite wide enough at the hips, it needs to be 2 inch wider for me, otherwise i like it alot

This is BY FAR the worst item I've ever received from Amazon. The quality is terrible, the cut is poor, the packaging was atrocious. They were all stuffed into a black plastic back and squished to the smallest capacity before vacuum sealed in. They're all 4 different sizes!Not a single on of them is the right shape, size, or has the right notches cut in them ANYWHERE. It looks like some 5 year old kid cut these with a butter knife. Absolutely terrible. TERRIBLE. I would give these a 0 star review if possible.I will be returning these and never buying them again. BUYER BEWARE.

The media could not be loaded. Terrible crushed. Not in package. Rolled up in plastic ball.
