Excellent so far
I just received it today. I put a small square attached to the sponge filter in my 3 gallon tank that I use for my two guppies. Within a few hours I have noticed the water is clear and looks excellent. My water was already testing well but I did just preform a small water change before the Poly-Filter arrived. I guess time will tell on how it works to keep the water perimeters in check. So far I am liking this product and I have a bit more peace of mind knowing something is in my little tank to help with keeping the water in check.
