PH Problem?

I started dosing Kent Marine Nano A&B religiously the past week or so and noticed today my PH was quiet low. I had a reading of 7.69 at 5:00pm but is usually around 8-8.1 during the day. Can this cause this?

How can i boost my PH without screwing up my other parameters.

Parameters of now:
Calcium - 420
Alkilinty - 11dKH
Phosphate - 0ppm (no algae growing either)
Nitrate - 0ppm
Nitrite - 0ppm
Salinity - 1.0245

As you can see below, some of my corals dont look to great, like my green button coral :(

Also, can someone tell me what the white stuff is on my rock (its circled). Im pretty sure its the bases of mushrooms, there was alot there....and there still there just very small now :(

Thanks,
MetalArm3

Lemon Jiuce will raise PH. Usually by airating the tank it will brin itself back up.

Lemon juice will raise pH? Lemon juice is very acidic with a pH of around 2. Maybe you meant pickling lime aka Kalkwasser aka calcium hydroxide.

To answer your question, the pH swings may be caused by CO2 buildup within the tank which is why RM suggested aerating the tank. You can determine if CO2 is the problem by aerating and testing the pH throughout the day (especially right before lights-on and right after lights-out) and comparing the results to what you get before aerating. If you're no longer experiencing that pH swing, then it was caused by CO2. However, this won't work if the CO2 is building up within the air because the purpose of aerating is to bring the water and air back into equilibrium; so if extra CO2 is in the water, aerating will strip the CO2 out, but if there's more CO2 in the air then in the water, aerating will bring CO2 into the tank and make the problem worse.

Thanks everyone!

Ill have to read that article tonight.

Should I be testing for any other parameters besides the ones I listed? My button polyp still doesnt look good . Or, do corals go through cycles? This happened one other time where it looked near-dead but than came back even stronger.

Im gonna go cold turkey on dosing Kent Marine Nanon A&B to make sure that isnt the problem (even though all my parameters are the the same from starting the tank almost a year ago).

MAG would be th eonly other test needed, but I really don't think you need to at thi point. Pretty much take care of the PH and see where it goes.

Can Do! I'm gonna pick up some ph buffer tomorrow and to a water change hopefully.

Thanks!

Update

Monday Night:

I added Seachems Reef Builder per instructions. PH rose from 7.67 to 8.00 and held for the night. I also measure alkalinity that rose from 11dkh to 13dkh ( sorta expected that). I then added Kent Marines Nano A&B in the hopes to maintain those parameters.

Tuesday Night:

PH- 7.70
Alkalinity- 14 to 15dkh

Wednesday:

So im planning a water change today. I also shut off my Two little Fishies Phosban Reactor be because I noticed the NPX media began to cake up.

Il update this again, but any new suggestions?

Ywa, point a powehead directly at the surface. I want to see what that does for you, before adding all the additives.
Question for you, are you running a skimmer?
