Hoping to get a little advice with phosphate issues.
My tank is several years old and I have only recently began using gfo. My phosphate got really high (2 ppm) so I started using phosban through a tlf 550 reactor. My levels dropped about 50 percent to 1ppm within about 5 days but havnt dropped since (about 10 days). Is it possible the phosban has absorbed all it is cable of and needs to be replaced? I though it lasts a little longer than a week or two..
Any advice is much appreciated.
