Frustrating day so far. Last night I noticed something didn't look quite right. I've been testing my alkalinity twice a day just recently because I ran out of alk buffer again (!) because the tank was just flying through it. Didn't have too bad of a dip, just minor. No big deal, grabbed a jug of the B ionic alk that the Dome carries, while I wait for my BRS order to get here. Things are going smoothly again and I'm slowly raising my dkh, shooting for 9. Well I tested it last night after feeling like something wasn't quite right and all of a sudden the alk is up to 9. That's great, just got there faster than I had planned. I'm using a doser and have kept the rate steady, so unless the doser malfunctioned, which I see no convincing evidence of, my alk uptake is inconsistent. That's frustrating. I lowered the dosing and it's only 9.3 this morning. I'll lower the doser again. So far I see some bleaching and hopefully that's it. I have some rtn at the base of an acro and I unfortunately can't get to it until this evening. I hope it doesn't move too quickly! And it would be nice if my alk uptake would pick a rate and stay there.
