Been a minute since I posted, tank is going through a bit of a rollercoaster with nutrients and parameters. Finally think I got it stabilized but lost a couple pieces in the meantime. The Core 7 is some potent stuff, my alk reading had spiked from 8.8 to 10.2 in 2 days somehow, partially I believe to be from new Hannah Reagent (accurate) vs the old bottle (never checked it against a titration test). But had to cut the Core 7 50/50 with RODI. I’m only dosing 1 ml of each of the 4 parts throughout the day, and Alk is finally steady at 8.8, which i think I’ll land on. My fuge exploded and my NO3 and PO4 ended up tanking a bit, after I had cut back on Roids and PolypBooster since they were trending up a bit more than I was comfortable. PO4 was 0.01ppm and NO3 had cut in half to a bit less than 10ppm. Will test again tonight to see if they’ve stabilized or are going back up/down. I also started dosing phyto, and think I will start to culture my own for a steady source for the tank.
