I just got an email back from Seachem support, saying that their buffer will of course also raise alkalinity, but if I have correct levels of calcium and magnesium, it won't have a negative effect on it. I've not worried about this stuff before...
This is all getting a bit complicated! All I want to do is raise my pH a bit
But not if it unbalances my tank and changes the alkalinity too much etc so everything becomes unbalanced...
EDIT: I just did an alkalinity test for the first time (one of those where you count the drops then divide by 2), and its come out high, at 5-6 meq/l. I wonder what's causing this? And, what can I do to sort it out and lower it?
I guess adding the buffer will increase it even more!?

I checked my calcium level today, expecting it to be low, as apparently high alkalinity usually equals low calcium. But it was high, at 480-500mg/l. I tested the seachem test with the reference, and it was a bit high, putting my alkalinity at about 5meq/l. My ph remains relatively low at 8.0 (lights on,11pm) just after a 25%PWC, and slowly goes down over the two weeks until my next PWC.
Can anyone help? Why do I have high alk and high ca? I dont dose anything. I have 2 hard corals, 3 soft, 1 shrimp, 4 hermit crabs, 2 turbo snails, and a bit of corraline algae growing. Shouldn't my Ca be normal/slightly low, rather than high?

What's the pH of your top off water?
If it's below 8.0 that could be where your problem is.

The topup water will be below 8.0 as its just normal RO. But, I barely top up now anyway after getting my lid (ventilated).
I was just surprised to see high alk AND high Ca, I've no idea why either are high!
Thanks for the link, I'll check it out.
