Calc Reactor ??????

janderson8 · 06/28/2006, 10:40 PM

I just tested my tank and my PH with light on was 8.05 my calc is now down to 320 and my Alk was 206 Meq/L. I have a heavy SPS tank.

First Question is will the Cal. Reactor raise both cal. and alk at the same time? If so what setting should I have on my reactor to raise the to the levels I need.

Second question what is the lowest I should expect my PH to go at night?

It sounds like you're just dialing in your reactor, right? If so, then you need to be dosing a 2-part like b-ionic while your water tries to 'figure itself out'.

Secondly, you should monitor the PH of the affluent- it should be anywhere between 6.7-6.9 on your PH monitor or controller. If your PH is too low, that means your tank Alkalinity will be too high and your calc won't be able to get where it needs to be. Hopefully you already know to either slow your bubbles down or increase drip to raise the PH of the affluent.

You should expect the PH to decrease at night after your tank lights are off, and this may happen more in the beginning while you're dialing in the reactor. Running a fuge light on opposite hours helps.
