Aquarium Biochemical Cotton Filter Foam Fish Tank Sponge 50x50x2.5cm by liannmarketing

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.

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

I bought the product to use in a fluvel 3, that I use in my indoor Aquarium. I just cut it to size roll it up and that's it. Plenty for the next 6 months, then I'll just order another.

Foam is good value and didnt take too long consdering where it came from. Packaging is not the best as the foam took a set. Worst issue its not large cell as photo.

I did get the sponges for my pond filter as they're are large enough to cut to size. A good price with free delivery. Did also arrive early. Excellent product.

I got a sheet of this to make filters for my shower / bathroom ceiling extractor vents. Looking up inside the vent hose you can see the solid accumulation of lint from towels etc. loading up the non return flaps. It coats everything. I measured and cut out a circle and put it inside each vent. They’re already filtering the air even after only a couple of weeks. They can be easily washed out. And they also act as effective silencers. I’m pretty sure there’s little airflow restriction.

Excellent product at a fraction of uk cost but for so much more. Ok it took a while to come but it was from China so to be expected and will be buying this from now on although this is gonna last a very long time. Great buy.

Bon produit

The foam sheet is 30 ppi with excellent material. I have purchased this product twice from the seller and seller is very customer friendly. Happy to use this product.

This sponge is cheaper to replace than those disposable filter cartridges for hang on back filters. It is porous but rough and is not the same type as those smooth cylinder sponge filters with the bubble tube. It will be more effective with a layer of floss and bio media. It might need two layers if using this alone. Just cut these up to the right size and it will last for a while.

Suelta grasa y huele a productos químicos,yo lo he tirado ante la duda de que pueda dañar a mi mascota

The product is not actually a foam, but more like a close mesh of plastic net. The structure is very good for beneficial bacteria. Fine filtration wont be possible with this. The actual size is 45x45x4.5 cm instead of 50x50x2.5 cm. So I got more volume of the product. As for the price, I think 499/-is very high.. Will update after I put that on service.
