brackish water mix confusion, going mad

[gagaliya]

Hi guys, really need some help with creating brackish water, a 5 min exercise has turned into a 3 hour ordeal, feel like i am going mad.

I am using
1) Instant Ocean: https://www.amazon.com/Instant-Ocean-Aq ... 130&sr=8-2

2) Digital salinity meter: https://www.amazon.com/dp/B08GC7JCV3?ps ... ct_details

Instant Ocean instruction says 1/2 cup of salt for 1 gallon of water, since i am doing brackish i did 1/4 cup of salt for 1 gallon (of distilled water). I am using a 15mL measuring cap (1/4 cup =60mL=4 cap of salt). After putting in 4 cap (60mL) of salt, my salinity meter reads 5100 PPM or 51 PPT! if i look up the chart, that's 1.0386 god damn sg argh. I double checked everything, cant find any mistakes with my measurement etc...

Does anyone know what the heck is going on? is the Instant Ocean instruction wrong? am i not converting the meter's 51 PPT correctly to SG. I am pretty sure there is no issue with the meter, if it is inaccurate it wont be this drastic. I think i am making some very fundamental mistakes but cant figure out.

20 years of planted aquarium, first time mixing salt and epic fail please help

4 tablespoons mixed with 1 gallon of freshwater will make brackish water with a salinity of 1.010

Get salt from this site you can put in at check out the exact size of your tank and they can send you pre measured amount.

You can remove some water and then add some distilled. You're fine. Throw out the meter. You do not need it.
