You introduced me to Rowaphos last winter, you might recall. And you made it super clear not to over-do it. I fought the urge to use a reactor and, now, seeing how far the Si has adjusted in 6 months I'm glad to have gone "low and slow".That's why when I introduce someone to rowphos you see me warn many times to not overdose and watch po4 closely. This media is very effective.
@svreef: yours should adjust from 192.5 in no time.
