Okay, so I use Randy's 2 part (actually 3, with Magnesium) I've always used this calculator, http://reef.diesyst.com/flashcalc/flashcalc.html , but for some reason, also have this calculator in my favorites, http://home.comcast.net/~jdieck1/chemcalc.html . Today, I decided to compare the calculators.

Today, I tested everything. My total water volume is 240 gallons. My Alk is at 2.3 meq/lt. My target is 3.2 meq/lt. According to the first calculator, the one I've always used, I need to add 14.6 ounces of solution. According to the second calculator, I need to add 29.2 ounces. Both calculators gave me the same amount of Calcium supplement to raise from 395 to 420 @ 24.9 ounces. However, the Alkalinity results are VASTLY different. Any ideas??

False alarm!!!

Helps if you put Recipe #1 into BOTH calculators, instead of #1 in one and #2 in the other.

I feel a lil' idiotic about now!!

Don't feel bad. I've done the same thing before. It is what I call having a brain fart.

LOL
I checked it before going on to your second post and came up with the same results as your first entry. When I used 1 and 2.

Are you sure its not from all of us turning into " an old fart"?

I refer to them as blonde moments

They are GREY moments for me!!!!

Who are you calling an "Old Fart" anyways?

Old Pharts Rule !!!

Remember what I told you on FB about your B-day...... You've officially crested the hill.


I'm right behind ya there.

In my case, this is probably closest to the truth.
