My Alkalinity is 5.4dHk today. A little over a week ago it was at 7.7dHk. I lost a red dragon frag, and a few recovering Acros. I didn't have a problem with my doser or solution and it had been stable for 3 weeks prior.
I had a bigger, longer dip in December and was really just recovering from that. Everything started looking better, but I guess as it grew faster, they used more!:headwally:
Anyhow, on to my question. I've always aimed for closer to 7dHk of natural seawater, thinking I was optimizing coral health over growth. But now I am wondering if I'd really be safer at 10dHk. A 2dHk dip at 10dHk puts me at 8, and while instability is always bad, a dip from 10 to 8 may be better than a dip from 7 to 5.
Sanjay Joshi says his tank drops 2dHk per day if his reactor malfunctions! And he has twice the water volume as I do. Does high alkalinity actual make things worse if something goes wrong? I am pretty good at catching doser problems, but don't always, and I don't have time to test water every day.
