I’ve used this in my 55-gallon saltwater tank for three months. The water clarity has improved significantly, and my corals are growing better. No strong odors or discoloration anymore. Easy to install and lasts longer than expected.
Peter Jones –
Works well for removing fish waste and ammonia smells. I noticed a cleaner water flow after adding it to my filter. Replaced it after two months as recommended. My plants in the freshwater section look healthier now.
