A Must Purchase For Ammonia Control!
February 4, 2022
We have a 14-year-old Plecostomus who has grown to 17 inches long, and anyone who has had this family of fish knows that they produce a good amount of ammonia to be offset... This product helps with the fight to keep readings under control :-) Charcoal is somewhat helpful in filters, but this gives you one more tool to keep your fish safe!
easy changing cartages :-)
might not be fully effective for length of time advertised :-(
