Aquacraft Bio-Sea Salt?

Trying to do a 5g waterchange with fresh RO. I put in about a cup and a half worth of salt and reached a SG: 1.0206. I then tested my alk with my hanna checker and got 3.864 dKh? Spoke with the owner of aquacraft and he said itll be fine and just continue the water change. He kept saying that my test kits are wrong and his salt is as great as it is. I am not going to dump a 5dkH swing into my tank by what some guy says.

Can anyone point out something I am doing wrong??

Nope. Your in the right. However, you did mean 1.026 correct? Not 1.0206?????? That would be bad!

Just making sure.

Most salt brands are usually 2 1/2 to 3 cups of salt per 5 gallon bucket to get 1.026

1.026, sorry for the mistype.

All the other salts I used in the past were to reach the proper SG levels and the other params fell in place. However for this brand I reached the proper SG and my ALK is only 3.8?

So you normally put one and a half cups of salt in 5 gallons to get 1.026? I highly doubt it

Yes. That doesn't sound right???

I'd double-check the SG device, but that sounds like a batch of salt that needs to be mixed again, or is defective. Another opinion on the alkalinity kit might tell you something, in theory, but I doubt that it's failed so suddenly. What is your tank measuring?

No, let's take reef crystals for example. There directions say, a half a cup per gallon... that mixes to
1.021, that's two and a half cups per 5 gallons and I want to mix to 1.026.

Am I completely off-base Bertoni?

No, I am puzzled by the SG reading. Salts can differ a lot in their water content, though. Something's strange.

If he's putting half the salt in the water, I can assume half a alkalinity reading.

I've gone through a lot of different salts, and for me to get 1.026, it's pretty much 3 cups of salt.
Salinity was around two and a half cups, same with Tropic Marin.

Thanks for the replies everybody.

In total I put about 2 cups of salt to reach a specific gravity of 1.026,
I went ahead and mixed another 5g bucket of RO with Kent salt, with the normal 2 cup ratio. The alk test for the kent was 8.344 dKh = 149 ppm. This was also with a SG of 1.026.

Its definitely not my test equipment. I believe you need to mix a way bigger batch than 5g to reach proper parameters with aquacraft.

:( Mixing up the dry salt might help, although I've never had to do that myself.
