Ok boys lets play nice. DSB's have a purpose and folks are free to run with them. What we want to do is to point out the good and bads of all systems, that way folks caan make up thier own minds. On Phosphates it is what it is, pretty hard to change mother nature.
Danny thier is no particular time table on this stuff, thier are to many variables (feeding, export mechs, maintence and so on) So you may be good for a good deal of time to come.
What I am trying to do here is to lay out the way thinngs work in our tanks, in this case in regards to P. If you understand the concept then what ever kind of filtration method you use, you should have a better chance at extending its life and making it work better.
Yellow I remember when you posted that info, you had me and Jerel rolling, great research and a great thread. thanks for that.
Mike
