How are you testing pH? Trying to adjust pH is a quick way to insanity and destroying your tank in the process. That isnt too low but right on the edge I would say. How low does it dip at night? What time did you record the 7.75? Morning or afternoon?

I wouldn't suggest chasing PH, as sometimes the testing equipment we use is not that accurate. Check and see if you have excess CO2 in your house or around your tank by opening up some windows around your tank.

Point your power heads up to create surface agitation and that might help raise PH as well.

Using a wooden air block in your sump can help raise PH as well, although it's not the save all cure all.

Dripping Kalkwasser will raise PH, as well as raise other parameters as well.

dosent having a higher ph result in faster coral growth or is that just a myth

Yes, some evidence out there of faster calcification at PH levels in the 8.3 area.
How do you know that your test is not off and it’s actually 7.9?
Do you have an independent test to check the test.
Unless your having a big party and have a lot of pets, PH should fall at least 7.8 which is where you are now.
Open a window, draw outside air into your skimmer, ensure good flow at the top, are some easy methods to get maybe .1 or .2 higher
PH tests are usually very inaccurate.
