![]() Lee,
I am running ARM in my reactor and have been keeping the pH at 6.9-7.0. I measured my alk today in my tank and it is still at 12 and my Ca is at 490. so you can run it higher than regular media. If you run it down near 6.5 it turns into soup. just so ya know. [img]images/smiles/icon_smile.gif[/img] |
