Filters work great.
January 15, 2017
I ordered these ammonia filters for my under gravel filtration system and they fit perfectly. I use this system as an additional filtration to my out of tank aqua clear system. This was my first order with this company and was amazed on how fast they arrived! I have had a hard time finding this product and was VERY pleased with this order from the Pet Guys. I will use them again.
ProsThese provide additional cleaning for my tank with my supplemental under gravel system.
