Regularly adding these bacteria to the pond filter increases biological action, optimally removing pollutants like ammonia and nitrite and breaking down organic material, thus preventing filter clogging.  *Concentrated formular*- MR KOIZUMI “FILTER START GEL” contains around 1 BILLION colony forming units per ml making it one of the highest quality pond filter starters available!
