10 lbs of DI @ 8.06 = 80.60
5 lbs of ca @ 2.85 = 14.25 = 94.85 plus 10 % off = 85.37 + 16.50 + 101.87

Is my math wrong?

I hope this is all right

Vanreefer:
5 cal - 10 DI $103.75 + 16.50 shipping = $120.25

I hope that is all correct, if not let me know. I entered it all in an excell file, so changing amounts doesn't really cause any problems.

I will pm you all my PayPal e-mail address, if it looks good send the money, if not I will adjust your order/correct a mistake and go from there.

Thanks.

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?

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.
