The specific gravity of combined Baling three part solution

[Koty]

Maybe its a stupid question: What is the specific gravity of the solution of combined Troping Marine Balling three part ? Isn't it much lower than 1.0264?
Asking because I want to get an estimation of the concentration creep up

Balling Part C, when mixed 182 g / gal, produces a salinity of 1.027 s/g

As for the other parts:

It's from this earlier article on the DIY two part where I added up the sodium and chloride over a year:


An Improved Do-it-Yourself Two-Part Calcium and Alkalinity Supplement System by Randy Holmes-Farley - Reefkeeping.com

Residue Remaining from Recipe #1 when using Recipe #1, Part 3B

After one year of adding 8 ppm of calcium and the accompanying 0.4 meq/L (1.1 dKH) of alkalinity per day (41 mL of both parts per day or 4 gallons of both parts per year in a 50-gallon aquarium, including the effect of the magnesium sulfate solution, 2440 mL/year), the following residue (Table 3) would remain after calcification and adjustment for salinity (there is roughly a 29% rise in salinity over a year using this addition rate without water changes):

OK thanks! so its about 30%/year which is:
0.08%/day
0.57%/week
2.46%/month
I guess the water lost while cleaning the skimmer and replacing the filter wool (I use a big chunk of it) minimizes it even more
I currently dose A (2x): 72 ml B: 150ml C (2x) :73ml. My tank is about 100g

Definitely. I have a skimmer and 5 filter socks. Each filter sock contains quite a bit of water. I actually never had to dilute the tank back down.

The skimmer helps also. It’s very convenient, as I dose a lot of 3 part.

I also dilute by not returning the 0.5 liters used for the TM hydrometer measurements.
