Polyfilter

Polyfilter is a pad you can put into any filter that chemically filters and purifies water ( I call it the magic pad) this is a fantastic product if you looking to remove ammonia, heavy organics ,copper etc and it changes colour for what it is taking outso you know what it is removing most.I also use it to polish up the water, and you can even use it if you are not sure what is going on in the tank. It really helps in all departments
