Best way to raise ph? Kalk?

If everything looks happy I would leave it alone mine drops to 7.8 every night with no issue.

Yes, you may be right, however, I have been having issues with my tank being unstable with it's parameters so I am starting to wonder if it is because of the ph swings. I can't get my ca above about 380 and I my magnesium is all over the map. Before, I didn't have to check my doser more than once a week. I am also setting up a ca reactor so my ph will possibly be even lower once I have it running. I have a controller but I don't want to run into issues once it is going.

Kalkwasser is one of many ways. Have a read and decide which one(s) will work best for you. I personally had my best success by drilling a large hole in the side of our house. But that may not be possible for other people. Low pH: Causes and Cures by Randy Holmes-Farley http://www.reefkeeping.com/issues/2004-09/rhf/

I use have a C02 Scrubber set up and attached to my skimmer input. I buy medical grade Soda Lime from a medical supplies place in the US. I did this rather then drilling a hole in the side of my house.

if ph is swinging a lot it is most likely because alkalinity is not stable or at ideal levels. although it does fluctuate at night

True but depending on how tightly closed up your house is this may cause excess CO2 levels lowering PH. my Alk is rock stable but notice PH swings. If I have more people in my house the lower my PH gets. In my case the Soda scrubber solves this and I have personally noticed my corals have been healthier and growth has increased because of it.

Of course everyone's tank conditions are different. What has worked for me might not work for someone else. As in Ryans case he has excellent growth and color despite PH fluctuations.

Ok well if your only wanting to adjust ph then soda ash is your best bet
