Maybe if you have a drip running to your tank it’d stay cleaner with them? Mine still got just as green and gunky. **Q: Weird question I know, but can these be cut?** A: yes... i'm betting a normal wood saw would cut them. **Q: I am thinking of using this in my horse's water trough. How many will I need for a 100 gallon tank?** A: Don’t waste your money. Have them in tanks. Don’t work!!! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Charcoal filter *by M***N on November 6, 2024* I use it for my horse trough. Don’t be fooled by the other website. Those are fish tank size and costs more. These are good size but remove before washing the tank because they are fragile. ### ⭐ Obviously don’t work. *by L***A on July 29, 2024* These have been in my water for a week now and the water is nasty!Will never buy again! ### ⭐⭐⭐⭐⭐ These are like magic! *by A***A on March 5, 2025* I don’t understand how these work but they are magic!
