Kalkwasser in your ato

Better surface water movement

Air line for skimmer from outside
+1, i prefer dosing Kalka on my refuge, i love Deltec Kalk stirrer, only clear water go OUT of reactor.
i run air fan at top of the tank, lots of water flow, i run air fan from outside IN room.
I have CO2 meter, years ago, i got better air on basement (600 ppm) then my bedroom (1200 ppm) i seal the bedroom a way to muck.
New York 450 ppm outside.
My shop 500-550 ppm.
I got 8.2 to 8.3 PH , your PH (8.0) is just fine. Leave the windows open to see if is any change.

If your corals look fine leave it. 8.0 is not that low. It may raise when the weather changes. Don't dose Kalk if you're not knowledgeable about it. It can crash your tank. Open a window, check alk dose A and B if necessary , raise salinity, extended lighting hours, add refugium and water change will bring it up some.

Is your tank having issues? If not i wouldn't worry about it. My tank doesn't go higher then 7.9 and it hasn't cause any issues.

8.0 is certainly nothing to worry about, but in a reef tank you will get better colors and growth if you keep between 8.2-8.4

Although it's more important to keep it steady

Check Magnesium, and Strontium levels. There are some good products out that target specific colors in corals. Basically minerals, traces and amino acids. I think Aquvitor not sure..

Aquavitro fuel is a good amino source. I've been using it for years dosing twice a week if i remember.

Since my tank is in room with no windows I built a simple diy co2 scrubber out of a Gatorade bottle. Drilled small holes in the bottom of the bottle small enough so the media doesn't fall out and ran a line right to my air intake of the skimmer. The media is cheap enough and color changes so you know when it's time to change. It kept my PH around 8.2.

That's the cheapest I could find the media.

Chasing dif elements to get at why your colors are pink instead of red....you know one reason, your ph is low, and should be pretty easy to fix. Less c02 = higher ph. More water surface movement, more fresh air getting to tank.

If that no worky than a couple of elements worth checking, in term of why your ph is low...
Alkaline and ph work hand in hand. It's not a relationship set in stone but in general as alkaline goes up, so should ph and vise verse.
Another relationship with alk and ph is calcium. When calcium goes up alkaline goes down and vise verse.
Magnesium. With regular water changes, with quality salt, it's prolly not an issue. but macros consume it, and if it's too low alk, and cal will swing around.
