DESPACITO 6pcs Fish Tank Filter Sponge Aquarium Filter Sponge Pad Cotton for Fish Tank Washable & Reusable Biochemical Sponge for Aquarium Filters Media Accessories Filtration Foam 38x12x2cm Thickness

Really good product it works as it says in the description of the product, only thing is we need to wash the sponge after 10days. I recommend this to buy

Filter Quality Good

The media could not be loaded. This product was life saving. My fish tank was covered with bacterial bloom for almost a month but I have added this filterproduct in my internal filters and it cleared my water within 48 hours of use.You should definetly buy one of these if you are having trouble in filtration of tank.

Little bit quality difference

I am new to this product & Aquarium Filters. And I have not yet installed this product into my Aquarium Sump since I have not completed building the Aquarium and Sump. But product quality looks good. Delivered on time.Kudos to the seller and Amazon!!Since I am new to this, I am not very sure about the pricing. But in my point of view, all these type of Aquarium Product prices are slightly high.

I have severely underestimated the size of the sponges. They are really thick and very big. I am using it for my stock "top of the tank" filter, cut vertically in the middle and using one part of it, cut about 75% of its length. Rest 25% i use to scrub insides of the tank. These does not look like they are going to unusable within weeks. They are of good quality and probably more useful for heavy duty filters which accumulate a lot of dirt. Overall a good buy.

Good quality, but slightly less in thickness than what I used to get in local shop..but far less costly. Highly recommended. I advise daily once washing to have clear water. Couple this filter with weekly twenty percent water changes, twice weekly Interior glass scrubbing for a healthy aquarium with clear water.

Not a good purchase, aquarium becomes cloudy
