View Full Version : Phosban

About a year ago I set up a 125 with the contents of a smaller system. Phosban was used in the older system and with the newer system I put on a Phosban reactor and watched my PO using a Salifert kit. I never had a reading and year went by with the same media. I switched it out at about that time, but was surprised by the long life. There's been no noticeable adverse effects. Can you please comment on this.
