I don't have a problem w/ phosphates now (in the 35 hex) but I vodka dose I am just wondering about the efficiency of dosing w/ my 150 now. Maybe something if it works for people I could add to the sump in the future.
How do they work?
They are so cheap, do they even work?
What do you put in there too "eliminate" phosphates?
I am just wondering about them.
Thanks guys!
