So I constantly struggle with a low dKh, and I believe it is what leads to my troubles with SPS.
Tonight,
Calcium 508
dKh 6.16
pH 8.17
I ordered some kalk mix and I am going to mix it up and add some to my ato to see if that helps raise things up a bit. I also have a pH swing from about 7.98-8.25.
Kalk should be here tomorrow, so we will see what happens.
On a side note, I am also going to be removing my biopellets and going back to gfo. When I first started with them they all stated how they lowered phosphates. Now everything says they lower nitrates and help with phosphates. I still have some algae problems, and when I ran gfo I never had a problem. Hopefully these couple fixes take care of the headaches.

I seem to be having the same problem, although I can't call it chronic yet. I've been mixing up a straight alk buffer and dripping it. I'm hoping to use a dosing pump soon so I can be a little more accurate.

the PH isn't that big of a swing. is it low before lights are on? then raise ?

For what is is worth, when running biopellets....you wanted your dKH on the low side, in the 7-8 range. But 6 is too low.
What do yo have in your system that is taking up the ALK? Check your Magnesium, if it is real low, that can cause Ca/Alk balance issues.
