I have s small tank. Livestock is one small fish, three snails, 4 hermit crabs and 15 small frags (LPS and SPS). I do a 40% water change once a week. I don't auto-dose anything, but I do dose Red Sea AB+ on Mon/Wed/Fri and Reef Enhance on Sun/Tue/Thur. My parameters are:
Before water change:
Alkalinity - 9.1
Phospate - 0.00
Nitrate - 0.00
Calcium - 472
Salinity - 33.8
After water change:
Alkalinity - 10.4
Phosphate - 0.00
Nitrate - 0.00
Calcium - 477
Salinity - 33.8
Obviously, there's some uptake of alk in a one week span. My question is, does the rise from 9.1 to 10.4 from a water change considered a swing or a shock for acros?
I want to buy an acro or two, but I'm not sure if the change in alk will shock them. I did give acros a shot a couple of weeks ago, but it ended up RTNing within 24-48 hours. Then again, it wasn't in the best shape when I got it and looked to be a maricultured piece.
Thanks in advance for the advice!
NOTE: I know I have to bring the NO3 and PO4 up for coral health and to battle nuisance algae.
