phosban question

[guinness]

I am using phosban by two fishes to help bring down my phosphates. I was wondering how long it was good for until it had to be changed?

It depends on your phosphate levels... it could last for months or just weeks. If you are currently detecting phosphates then change it when the levels stop dropping.
