that piece of paper is the mixing guide - there is a pdf of it on the ESV site if you are interested.


I need to get a digital scale so I can mix this stuff perfectly.

You can try splitting everything but i dont think this stuff has shelf life as long as you keep it properly sealed. I only have a 45 gallon tank and will do 5 gallon changes weekly so it should last me 6+ months.

Thanks the the photos! That box does look pretty rough.

I'll think I will order a batch.

lol yeah the boxes they came in looked horrendous man. I think they are rated for 50lbs max and they weight like 48lbs. It was clear mine was at the top of a pallet because it had a giant band gash in the top. Everything was in good order so i cant complain.

Just got my RO hooked up and am cleaning up the water holding tanks. Might grab a scale from the "herb" shop this friday so i can mix some salt.

so i mixed my first batch today - 12 gallons. just to soak my eco rock in. Doesnt take too long but i had to sit down and do some math because i didnt get a scale yet so i had to figure out how many cups/tsp/tbsp i needed. It mixed pretty easy but i havent checked the levels. My test kits and refractometer are packed upstairs and i dont wanna wake the kids. I'll post the mix results tommorow.

fwiw - if you are using a 5 gallon bucket you will only be able to mix 4 gallons of salt.

Correction... premiumaquatics has 200 gallon mix for $270 shipped. Their shipping calculator doesn't handle heavy items correctly.

Shipping is $9.00 anywhere in the states, but $191 more to go another 8 hours north of the border.

I'll be getting a salt mix locally until a Canadian dealer starts carrying ESV.

Phi, interested to hear how your tank likes the new salt.

alright - so i mixed as per the directions... salinity was low. about 31.5ppt. UGH! Did some research online and it looks like other people are having a similar issue. I calibrated my refractometer with Symbon 35ppt solution that was floated in my mixing water so the temps were equal. ESV's directions are supposed to mix to 34ppt.

I guess the good thing about this mix is because its a component salt i can just add some more pure salt.

The other people who had issues online calibrated all measuring devices again (*ie. scales, measuring cups) and re-mixed and also got low salinity again.

I am going to try to mix with scales next time and do a mix on a single gallon to figure out the exact amount needed per gallon and post my measurements. I have yet to measure the other parameters but will do so once the salinity issue is corrected.

I believe the included results from ESV are incorrect but I cant say for sure until I do a control test with weighted components instead of measured.

I just added another 1/4 cup of salt and the salinity appears to be dead on at 34ppt.

also - i picked up my salt at $71.99 a couple months ago from Premium Aquatics but had it shipped to the border.


Its about a 45 minute drive one way to the border from my house.
