I have a Schuran Jetstream Pico, just got it a few weeks ago. It boasts that you don't have to use much CO2 but the reactor media melts at a way lower pH (about 6.4 compared to 7.4-7.6 with ARM) so I don't see how that figures. Anyway, I just discovered the lower pH info so I've been putting more and more CO2 into the system. I have my alk in the right spot but the ca and mg haven't caught up yet so I guess I'll have to get those in order manually
