**Q: what are the ppi ratings?**
A: No

**Q: Do these fit the trays of the sunsun hw-3000?  i've seen at least one review say that the pads are much too small & do not work.    thank you!**
A: I have a sun sun 304B & HW-3000, the baskets & foam sponges are the same exact size in both. Only difference is the head of the filter. Hope this helps.

**Q: will it fit HW-303B?**
A: Not well.  They are slightly too large for the 303.   They can be used, but must be compressed quite a bit.

### ⭐⭐⭐⭐⭐ Review
*by N***8 on 13 February 2024*

One of my canister filter for my 155 gallon fish tank is a Sunsun Hw304B bought in 2016. It has gotten partially clogged lately. My fish tank water became stink and cloudy. I could hardly see my fishes. Received the pads today and installed right away. About 4 hours later, the fish tank water became sparkling clear and not stink any more. The performance of these perfectly fit pads is way beyond my expectation. I thought it would take days at least. The price is quite reasonable too. I am glad I bought these pads instead of a new canister filter. Will recommend to anyone without hesitation.
