PH Question

[Mike from Penna]

Hello All,

I was hoping to get some feedback on my tanks PH where I have LPS and some softies. I'm trying to do a better job of controlling my parameters than I have in the past.

In an effort to raise my tanks PH closer to 8.3ish I added a BRS CO2 scrubber. Currently my scrubber is attached to the skimmers muffler nipple and I also ran a line from the scrubber to the outside air through the wall. According to my Apex Fusion (which was recently calibrated) the PH is now ranging between 7.9 (Nighttime) & 8.2 (Daytime). Is this range and magnitude acceptable for torches and goni's or should I look at other measures to make the range more consistent and the magnitude closer to 8.3 or 8.4? If so, what would be the next step? Kalk?

Please let me know if anyone has any additional questions to help formulate an answer.

Thank you, Mike

IMO those numbers (7.9/8.2) are great numbers. Not sure what your Alk. is but I use BRS two part soda ash to keep mine up between 9.5 & 10.0 and that raises the PH a little also.

I agree those pH values are fine.

If you have a refuge with macro algae run the light opposite of the tank. This may help with night time ph drop.

Thank you all for your responses that makes me feel better.

My Alk ranges between 8.3 and 8.7 as I'm also running BRS 2 part soda ash. Do the targets below look acceptable?

Parameter Targets:
Alk: 8.5
Mag: 1300
Calcium: 400

Thanks, Mike

I keep my Alk (9.5) and my Calc. (450) a little higher, but your numbers look fine.
