Ocean Pure salt

[danny zubot]

Oops, I forgot to mention that I'm using the OP Pro salt as well.

When mixing a 5 gallon bucket I found that the usual 5 scoops (2.5 cups) gave me a salinity reading of 33ppt as opposed to 31ppt with IO salt.

Heres what I got from testing right after mixing and testing again 24hr later.I had some Ca precip on the inside of my mixing pail (32g Brute garbage can)So the second CA test wasn't very reliable.

New salt=Oceanpure Pro
Fresh mix
ca = 380
alk= 12/4.28
mg = >1400 color changed to dark purple/tinge of blue rather than grey/blue tested 2x
no3= .5

New Salt @24hrs
ca = N/A picked up precip from mixing container tested 2x,first was 500,second no color change.
alk= 11.8/4.23
mg = 1470 definate color change this time
no3= .5

would be interested to see others test results so I know mine aren't wonky.Looks good tho if they are right.

Hmmm wonder why you're getting NO3 readings, that's not a good sign... Do you have a high sensitivity PO4 kit (Merck, Hach etc.)?

.5 no3 isn't a problem,My no3 generaly tests around 5-10 ppm before w/c,so given that,Im still exporting alot more than Im importing with a water change.The first test I used untreated tap water to mix the salt,because I just mixed up a glassfull to get the test results.I thought at first that was the cause.But the second test after 24hrs was going into the tank,so it was filtered water.Now Im thinking maybe a dirty test tube,or something like that.No PO4 kit,the cheap ones dont work and the expencive ones cost around the same as a phos reactor.So I got the reactor and grow Chaeto.

i used to use OP when i started my tank a year ago and 2 bags of salt that the calcium precipitated. they replaced the bags free of charge but i didnt want to risk it anymore and switched to IO.

It's funny, because I have the same sentiment about IO, lol.

I tested my tank levels last night after about a 20% water change with it. Can't really comment in a scientific way because I didn't test first but I was suprosed by one result. My Mg was around 1280ppm before the water change, and last night it read 1360! Finally a salt that actually supports Mg.
