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.

That wasnt enough money to get you accross the border...lol

any updates?

Yep, going to France in a few weeks.:mrgreen:

Hasn't arrived yet. I will post on this thread when it comes.

Come & get it. The LSMax order of chemicals from Winterpeg arrived this morning.

They seem to be bagged individually but I don't see tags on them to ID who gets what so we'll have to figure it out when you get here.
