Ph

One of there ways, test need to be replace, fresh air to the skimmer, or baking soda that has been bake at 300 for 1.5 hrs. the baking soda method will raise your alk though.
 
What is the pH?
 
I would not even address the pH until the tank is fully cycled, the pH is going swing until the cycle is complete. If you have not added any live stock just sit back and let the system cycle. You're wasting testing supplies and supplement products if you attempt to correct the values now.

First post a dkh of 9.2, in post#9 a dkh of 14.00?

If after the tank has completely cycled you're still seeing a pH lower then 7.8 chronically then consider one the many methods of maintaining a higher pH value.

Remember pH values raise and fall in a 24 hr periods, with the lowest values present when the lights have been off.

What did you use to cycle the tank?

don't worry about pH in a cycling tank, the byproducts of cycling it will drive your pH down, but who cares what that ph is since you have nothing in it yet. If your pH is 7.4 in your established tank, then I would worry about it. Not the pH value per se, but what in the world is causing it to get that low. Don't chase pH but look at it as a tool to make sure that you are playing in the right ballpark.
Is the pH that low in the cycling tank or the established tank?
 
Your best bet of getting close to true numbers with hobby grade kits is to have multiple of them and take multiple readings.

As far as the air mentioned earlier, you don't just need an air stone you need fresh air from outside injected to your tank to remove excess CO2 and raise the pH. A lot of people though run an airline outside their house and put at their skimmers intake. Another solution is a refugium with macro algae with a reverse light cycle from the dt or a 24/7. But what i would try as an easy test would be to open a door or a window in the room the tank is in for an hour or two and test pH afterwards. That will probably make a difference. Do you have any means of promoting gas exchange (power head pointed at the surface, sumo/overflow, skimmer, flow etc)?

So to summarise, if i were you, I'd get a salifert test kit, take pH reading with both kits before and after opening the door and take it from there...
