z&p parameter?

[reefpeeper]

you guys who keep z&p how important do you feel it is to keep an eye on your cal and alk? is there a certain level you keep it at for z&p

Z's and P's are easily impacted by pH, Alk and I believe there is a relativity between alk and Cal.

What kind of impact do ph alk and ca have on zoas. Mine aren't very happy and I have low ph 7.8-8.1 due to co2. Could that cause a problem?

 

[650-IS350]

I run mine at 8.2, but they get ***** when my alk swings from 10 down to 8 or even 7. as I manually top off and manually dose.

My Z's and P's are my tanks earlier indicators of something off with my parameters as any difference in Alk, ph, Temp or lighting and they start showing being PO'd.

alk 9 - 9.5 dkh
cal 430-450ppm
mag 1320-1350

If the alk drops then all the z/p start closing.. I have found that 9-9.5 is best

alk 8-9
