The reason to go higher is just a safety zone.
I drip full strength kalk 24/7, don't care how much. If my levels are off at my bi-monthly test taking, I adjust up by adding turbo calcium/baking soda, or lowering by just adding RO water for a day or two.
Finally, pH will fall and be lowest in the am before lights on, highest at night before lights out. A swing og .3 is perfectly fine and expected in a well stocked tank.

Hi Brad,
Tks for all the comments. My SG is at 1.025-1.026. I always believed that to be good to your reef you needed an ALK of 11-12 DKH and calcium in the 450 ppm range, I'm happy to hear that it is not necessary.
I currentlt drip kalk 24/7 (2 teaspoon in 2 litres of ro/di water) plus I dose ESV B-ionic 2 part solution daily (aprox 60 ml of each solution)...am I doing something wrong here, when I test my parameters are as follows: calcium 350 to 380 ppm, alk from 7 to 9 DKH, my ph is at around 8.2 to 8.25 at is highest..and 8.0 at its lowest...by driping kalk 24/7 at my current mix..shouldn't I see a higher PH??? also is it a good pratice to drip kalk and add the ESV 2 part solutions...or could I just get by with kalk only???
I appreciate your comments on this ..tks Marco
