Review: Just the job for home made filters. - I ordered this with the idea of making up my own filter blocks for my Superfish Aqua Flow 100, as the cost of two official replacement cartridges is around double the price of this stuff. I was set for a lengthy wait for it to arrive, but it came much sooner than expected, so well done to the supplier. I cut suitable size squares and managed to fit 3 layers in the cartridge. I cut a hole in the middle layer to put some activated carbon in and the whole things is working like a dream. The old filter sponge was causing the filter to struggle, making it very noisy with a chugging sound and the water flow kept slowing down, even after cleaning. I found that I was having to clean it every day. Since using this foam, I haven't touched it now for 3 days and the water is still flowing clear and fast. I am very happy with this foam as it's an ideal replacement and there's enough to last for ages.
Review: Late arriving but exactly as described - I'm very happy with the sponge aquarium media, it is very good value. My only concern was that it was three weeks late in arriving. It would have been helpful if the seller had let me know, I was about to cancel the order when it arrived.

I'm very happy with the sponge aquarium media, it is very good value. My only concern was that it was three weeks late in arriving. It would have been helpful if the seller had let me know, I was about to cancel the order when it arrived.

### ⭐⭐⭐⭐⭐ Good product
*by M***Y on 10 May 2023*

I will certainly buy this again. Cut to fit any filter size. Have used this for a while and no signs of deteriorating.
