Should I be concerned about the low PH? If so, would baking soda raise it?

Thanks

yes baking soda works great but raise it gradually, stability is more important than the specific # it is-

what I was saying is no, don't use baking soda. Find out why the pH is low and correct it. Then the pH will be "normal"...

I agree with Aquattro, don't screw withthe pH. Don't even worry about the pH for the first month...you shouldn't be putting any critters in there in the first month anyway.

My PH was low when I first started also. I was using RO water with a good quality reef salt, but was told that I should be using salt especially for RO water. Seems to have helped. My PH is now around 8.0 in the morning and 8.2 in the evening.

Also I 've noticed that the PH levels are quite wacky when the battery gets low on the PH monitor.

More likely your live rock simply finished re-curing which stabilized your pH. Let me guess, an LFS convinced you to buy this "special" RO-water salt.

Of course. Since I had only been doing this for a few weeks I knew I should buy everything they recommended.

Couldn't be more correct. pH although important should never be touched with actual PH chemicals. Use your salt and additives to buffer your pH to 8ish.
