Nothing much new to report.
I ran into a poor moment, with school, and ran out of vitamin C at the same time and haven't been able to re-order it. Tank has gone about two weeks with no dosing, and nitRATes and Phosphates remain undetectable (this is with NO water changes done), so i'm curious now. I plan on re-dosing ASAP.
As per your question Nick,
I never used macro to begin with, although I greatly suggest taking it out as my friend who dosed has his macro literally melt after a couple weeks. That being said, Trevor (AKA Wildechild) on here has been dosing at a very low concentration and has macro which is still intact.
I was running GFO in my 29G prior to starting Vit. C dosing, but soon stopped after a few months of dosing. My 75G, I have never used GFO.
