How much should I raise alk at one time?

[Darryn Lyon]

Used to run my tank at a high alkalinity, around 10.4 -10.7.. a friend suggested trying to let it fall lower and see how things looked and things are much better around 8.4, which is where I'm aiming to keep it. I have a 32 gallon biocube and my alk tends to slide relatively quickly, somewhere around 0.1 dkh per day.

I have Seachem reef buffer, but sometimes when I use it, I add a bit too much and it shocks my coral. How much can I safely boost my alkalinity in one dose without shocking or risking anything? (0.4 dkh, 0.5 dkh)?

I was always taught no more than .2 dKH/day.

IMHO no more than 1dhk in a 24 hour period.

I believe BRS says 1.4 Dkh in 24 hours. Anyway you slice it it's probably safe to say the slower the better.

I agree with 1 dkh in 24hrs its best to break up the dose because it raises ph in the system
