Let's see 5 lbs of cal @ $2.57/lb = $12.85 10 lbs of DI (my sheet had it at 8.08/lb.????) @ 8.06/lb = $80.60 shipping $16.50 Total = $109.95 so I was off by a few cents. You are taking 10% off the DI price per lb, the $8.06/lb is the 10% price. FWIW you were quoting off the first price list where I forgot to take off the 10%. I am 99.9% sure the $109.95 price is right. This is what happens when I do math at work. FWIW I always double check everything when I am at home on paper.

Hi littlesilvermax
Do you have any suggestions on the quantities of Mag and Cal required to bring a 50G mix of Instant Ocean up to acceptable levels? Tom R

I haven't measured magnesium in 3 years. I use IO only. I add about 250 ml to 40 gallons of IO made water, I do this prior to a water change. That increases the magnesium from about 1200 to about 1380, which is closer to NSW. I then add about 8 teaspoons of calcium to the mix to bring IO's 350 ppm to about 430 ppm. FWIW I always add the magnesium and calcium to the water BEFORE adding the salt. I have been doing my monthly water changes like this (w/o measuring) for years now, and my mag, alk, cal are always very good. (I assume 1380 for magnesium, but I don't check anymore, 9, 430) I usually check the test reports on RC and here regarding levels in IO salt, and it seems to be fairly consistent. I disregard the users that test one small batch, as it is not always mixed evenly through-out the pail. I go through about $15 of magnesium a year, and I save the $37 for a test kit. Hope that helps. For 50 gallons that would be 310 ml of magnesium and 10 tsp of calcium.
