ESV Salt test results

[Jim]

I just tested a 30 gal. batch of ESV salt that I measured the dry parts with a scale for the first time. ( I usually just use the measuring cups.) These are my results. All tested with Salifert kits.

Temp 78.5
S.G. 1.025 (w/ refractometer)
Mag 1410
Cal 500
Alk 9.9
pH 8.3
Nitrates 0

Just curious to see what others ESV users get.

I gave up and went back to reef crystals lol, but when I was using it I would come up with 1.020 :-/

Curious what the difference between your old method of measuring salt parameters were versus measuring by weight? (Believe we spoke over the weekend at GA)
When measuring salt by volume I ran into the issue of magnesium being too low, trolling around 1200, which turned out to be when measured by weight, close to 30 grams per 8 gallons of made water off to tune it to 1300 or 60 grams per 16 gallon water change I do 2 x a week.

The good thing is it is easily corrected with accurate dry weight measurement of ESV sodium cloride and magnesium sulfate so you can dial in your batches.

When I made up this batch I first used the measuring cups and put 9 cups of the first dry part into a container. I then gradually put it into a container on the scale. When I reached the correct dry amount, I had about 1/3 of a cup left over. So there was a definite difference. But when I did the same with the 3 cups of magnesium, it was very close to accurate. I think I added maybe a gram to reach the proper weight. But obviously the parameters I reached using the weight method were where they needed to be.

I uses their cup and scoop measure..

I played with it until I m aware what to add etc...

1025
77*

Mg-1380
Alk 9-9.5
Cal - 440-460

Ph at night 7.8 , daytime 8-8.2

Usually I tested after mix and tank to compare and see what need to add little more etc.

Mid of week I test tank water para and usually cal drop little fast so i have brs cal mix to add it to my tank to raise to 440-460.

Alk always dead on 8-9
