Confused on Alkalinity Results
 

So on the 7th of December I tested the alkalinity at it came back at 11dkh. I thought that was a little high, but attributed it to possibly not stirring the salt.

On the 16th of December I tested and it came back at 14dkh. Now thats weird that it would have went up without a water change or any additives added.

Changed 12 gallons of water on the 19th of December.

Tested again on the 23rd of December and the alkalinity came back at 14dkh once again.

Now Im confused, 14 is suppose to be on the extremely high side from what Ive read. Not sure as to why it would be so high, why it went up, and why it wont drop. All my corals look fine and the pH, calcium, and magnesium are all coming back at good levels. Ill add Im using IO salt.

Any ideas?

Calcium reactor could be the cause.

I am not running a calcium reactor. I have a profilux doser but havnt had a use for it yet as I have few corals. I have not added anything to the tank for supplementation.

have you tried a second test kit?

This I will have to do I guess

did you test the first time right after the water change? Do you let the saltwater sit overnight?

The first time I tested the tank had been running for 3 weeks. I usually have the salt mix for 24 to 48 hrs in a brute

well, like the other guy said, try a different test kit. You appear to be doing everything correctly.

I'll do that and get back. Salifert kit seams to be failing me
