Well...my multi head torch has died on me...lost the last head last night....my guess is due to low alk levels that i have been trying to raise the past week...attached are my readings for the past....note i have been running Kent Phosphate Sponge in a bag in the back of my RSM250 as needed for phosphate...my question is what should i be aiming at for alk levels. I was thinking around 9dkh...but was hoping Randy might chime in....tank has been up and going for about 4 months now...thanks
