Prazipro in the reef - once and for all

[tytown]

So 2 weeks following my treatment i've noticed a decline in coralline and macro (dragons breath) algae health. It seems to be going pale and almost brownish.
This could be due to a recent drop in dKh (sitting at slightly above 5) but just a heads up. Im dosing to correct for the alk drop, but will keep updates coming. Im not 100% sure the issue was from the prazi but I should be able to confirm based on how things look once i get my alk back up.
Nems, inverts and fish still doing fine.

It could be one more thing, I used a lot of carbon following a large water change on my system. Perhaps a slight overdose...
