How do i go about getting it down? Ph was low so i dosed with Ph buffer, and i think that is the cause. Calcium is a little low at 340. Any suggestions or will it happen over time? I am now mixing water for a 15% water change tomorrow, anything else i should do?

If you checked just after you added your buffer, you may be getting a false reading. It will come down on it's own over time, or you can do a small water change. Just don't start chasing numbers and doing things you'll regret later, let things settle on there own.

Alkalinity will go down on its own over time. Bringing your calcium up will help. Use calcium chloride alone to do this.

Read this:

Then use this calculator to figure out how much calcium chloride to use:

Then read this about how you should have approached your low pH:

Definitely stop using buffers to try to raise pH. There are better ways:

My pH was always low (7.8) ,lfs told me to buy buffer.
Instead looked here and read to vent tank. So i removed
old hood and replaced with eggcrate. Problem solved.
pH is now 8.2 or so consistantly. It was also a good excuss
to upgrade my lights.
