High Alkalinity in New Salt Mix

[spartanph]

I just mixed a new batch of water and tested.
SG 1.025
Alk 12.2
Calcium 450
It is a new tub of salt. Reef Crystals. How can I bring the Alk down or do I even need to?

bump

I use reef crystals and my alk is usually around 7 after a change and I add seachem's alk powder to bump it up some.

 

[spartanph]

Can anyone tell me if I need to worry about this level of alk?

 

[lubeck]

Yes,,,,depending on how many gallons your going to change at once.

 

[spartanph]

I usually change 15 gallons of 85 gallon tank every 7-10 days. How do I bring the alk down?

When your taking your measurements how long has the new saltwater been mixing for?

10-4. And calcium is usually around 350-400. Defintely not 450. Spartan, are you mixing with ro/di, or tap?

 

[spartanph]

Using Salifert test kits after new saltwater has been mixing for a few days to a week. For a reef I've read that calcium of 450 is ideal.

Oh and using RO from LFS
