How much do you dose?

I'm sure it is but is your mag staying at a good level Alk won't rise or stay high with a low or fluctuating mag level, that's about all I can think about. Also I've read some stuff on GFO and Alk levels changing out too fresh gfo can drop alk levels a bit

Just my 2 Cents

Thanks for responding. I am using up the last of my BRS Soda Ash in my latest batch and I mix it as per their directions, 2 x 8oz cups for 1 Gallon of RODI water. My Doser does 1.1ml per minute and I dose 11 minutes every hour.

I haven't tested Mag in about a month but I was at 1320 last time I tested. CA is currently at 500 and I've cut back on the doser for this. It was maintaining at about 430-440 for the longest time, but something has changed and my CA went up over the last month.

I use a Kalk stirrer with my ATO but due to how it needed to be setup, very little of my ATO water goes through it (about 10% at max) while the remaining 90% is pure RODI.

My hose came off my doser last week and my alk has been low too and high Ca. I just cracked open a window last night beside the tank and it seems to have stabilized the alk a bit better. I read somewhere about having high CO2 the alk won't absorb as well. It could be just coincidence but my alk finally stayed over 7.

About 500g of water and I dose 384ml per 24 hours, relatively new tank with Coralline algae growing like crazy lots of frags I use three part dosing.

Alk is @160ppm and Calcium is 410 and Mag is 1380

No worries about the newb question. My tank is quite populated with corals, specifically SPS corals who absorb the CA and Alk and Mg during their growth. Without it, they stop and become very unhappy corals. You can offset this with water changes some but the larger your tank, the larger the water changes...which become cost prohibitive.
