Hi there!
I recently switched to Tropic Marin Pro Reef salt and have found my calcium and magnesium are now rather high, at about 500 calcium and 1480 magnesium.
I think this is because I have been mixing my salt up to 1.026 sg, resulting in an alk of 7.7-8 dKH, calcium of 470 and mag 1440. I will try mixing at 1.025 to bring this down a bit (my aim was 440 calcium and 1350 mag).
Additionally, I am dosing TM All-For-Reef to maintain Alk levels, but I think this is resulting in an overdosing of calcium and mag as a consequence of the already high salt values that I am adding. Given my system is under a year old I can probably get away with just dosing alk at this point and doing my weekly 10% water change. When I was using pre-mixed water made with Red Sea the all for reef dosing was okay.
Does mixing the salt to a lower salinity and switching to alk-only dosing sound like a reasonable idea?
Many thanks,
Chris
