Hello again Marc
If you enter numbers with a decimal point like say

Desired Salinity in ppt = 33.8
Actual Salinity in ppt = 31.2
Tank Volume (litres) = 200
Answer = 519.99999999999999 gms.

Could your 5016 grams of salt have been 501.1 (Five hundred and one point
one) and you missed the decimal point?

I hope so
Please let me know as it was not my intention to mislead people with my
calculator


Regards
Grimreaper

Have no worries. I just was curious how to convert from grams to cups,
sicne I don't have anything that measures in grams here.

I used your chart and entered the appropriate data if my salinity was
1.023(31.2ppt) and I wanted 1.026(35ppt) with a system volume of 330g of
water. I think that was 1320 liters (4 liters being equivalent to a
gallon of water, roughly).

So that would be 5016 grams. I just ran your page one more time to get
the right numbers.

I'm glad you are trying to help others. Excellent. Keep it up. :)

Marc

GrimReaper I somehow missed this whole thread and I can't get to your
calculator as it's over 10 days. I'd really like to have it as I'm
filling my first salt water tank right now. My email address is
miskairal [at] [gmail] [dot] [com] or I can return to your site and try
again if you'd prefer to put it there (assuming of course you don't mine
me having it).

Thankyou
miskairal
