I just tested my Alkalinity. It was 15 dKH or 268.5 ppm KH. Is this number too high? The test booklet says it should be between 8 - 12 dKH. Could this be the reason that I lost my 2 fish earlier this week?
I think that's the problem. The buffer is baking soda and boron. The boron helps control the pH, but it also raises the borate level and it screws up the readings on most alk test kits. What brand test kit do you use for alk? Unless it's Seachems test kit, which they modified for use with high boron levels, chances are your test kit isn't giving a true reading.The only additive that I use is Marine Buffer. I only use it when I do a water change, to keep the PH up. I will do another full water test, and then post all of my parameters on here tonight.

No chance it is a bad test? When I started my reef tank.... I had major issues with bum test kits.
If it really is that high...just be careful not to bring it down too fast....
It's DEFINITELY the Marine Buffer.
I had the same issue when I got into dosing my tanks with that same product.
NONE of those buffers will really correct the problem of low pH. All they do is jack the alkalinity way up. It gives you as good pH reading for 6 - 12hrs. Then your pH readings will be low again. You can test and watch the pH remain pretty much constant over a 2 week period - and the buffer cranks your alk up too high.
The best thing to do is quit worrying about it. Stop dosing those buffers. Change 10% or 15% water weekly and just learn to live with it.
A STABLE pH of 7.8 is MUCH MUCH MUCH better for your corals and fish than a pH that swings rapidly up and down from day to day - and an overly high alk level.
Just get it stable. Stop dosing. The corals and fish will adapt and be happy as long as your pH isn't too far below 7.8 or 7.6 -- low pH is better than wildly swinging pH. Just keep it steady.
