Aquaforest mineral salt

[michaelr7170]

Hello,

I started dosing Aquaforest KH, Ca/Mg, and mineral salt along with dosing AEBV every other day, around one week ago. My system is a 180 gallon sps dominant with about 220 gallons of total water volume, when you include my sump and refugium.

I mixed the recipes as per the instruction on the containers, and in the aquaforest guide, currently dosing 100ml/day. My levels this morning were, alk 7dkh, calcium 405ppm, mag 1400.

I have a neptune apex controller in my system, and my salinity has been reading consistently around 32.5ppt for about a year now, which corresponds to 35ppt on my refractometer. However, since I started dosing aquaforest products, it's been slowly climbing, currently at 33.4 - 33.9 ppt.

Is it normal for salinity to rise when dosing mineral salt? Or am I missing something?

Appreciate everyone's input!

Not sure what mineral salt is, but dosing calcium and alkalinity will also raise salinity when done the way you are doing it. :)

The mineral salt is the NaCl free salt, part of the 3 part dosing scheme. I dosed a 2 part calcium/alkalinity mixture all along but never seen an increase in salinity to this degree, my skimmer seemed to keep it balanced..

Yes, it will raise salinity, but not as much as the calcium and alkalinity additives. :)
