We could not say it will 100% work with a different item, even though it may well do. **Q: What size are these? Width & length? Want to use instead of aqua filters** A: The product - as indicated in the illustration - is contained in 3 sealed package in a box. It actually has the very small size of a grain. I bought mine to clear the water clear in hyacinth bulb glasses. This product is similar to "Eheim Karbon" which I bought for the same purpose. Since I do not have an aquarium, I regret not being able offer an opinion as to whether either of the products I have bought would be appropriate to meet the enquirer's needs. Adrian Clark **Q: will they fit an external 307 filter ?** A: I just put two bags in my 307 :) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Small bags so check the details *by J***B on 16 June 2026* Very good but smaller than required.
