Whats the best Ca, dKH and Mg for sps?
I have always heard and been told that you should keep your levels in this range:
Ca - 380 - 460ppm
dKH - 8 - 12
Mg - 1250 - 1600ppm
now these are a big difference between the two sides of the scale.
I was told that you should keep your dKH high as this will keep the pH change from day to night as minimal as possible. So with doing this you are also keeping your Ca and Mg in the upper scale (if using a ca reactor like me).
But i have heard of people 'burning' there acro colonies from having a stable high dKH.
But i know that we all want to acheive the Nsw levels as much as possible, which is:
Ca - 420
dKH - 8
Mg - 1400
But i was wondering what was best, whether to have a lower dKh (eg 8)and risk the pH fluctuation, or have a higher dKH (eg 12) and risk acro 'burning'?
Whats your thoughts?
