Yeah, I’m loving the AFR and so far I’ve been doing it correctly, I just get nervous on chemicals cause science ain’t my jam. But Tropic Marin is so great on tutorials and I enjoy watching Lou’s videos because he talks in layman termsI will say I'm having much better luck keeping levels stable while dialing in the AFR than I did with the ESV 2-part.
With the 2-part I could pretty consistently manage calcium and it matched up with the online calculators. Alk on the other hand did not match the calculators and the same dose would have a different effect on different days; really puzzling. Though the ESV Ca is good to mix in with my new batches of water since the IO I have mixes low.
