Hi, so I got an RO system, and all the water parameters are good except the alkalinity which is 15. Is there some problem with my RO system, if so, what should I look for?

I am using IQuatics Reef Salt, and my test kits are Sera and Salifert (the alkalinity one is Salifert).What salt are you using? Also what test kit are you using and how old is it?
The salt has an alkalinity of about 10 dKh.
My tank is about 5 months old.
I do water changes biweekly.
I have live rock with live sand.
I am only dosing sugar water and prime to keep nitrates in check, and about two weeks ago I was using something to adjust the pH.
I do not have a cal reactor.
I did just test the RODI water, and it had an alkalinity of 15
Take a water sample of your tank water and your rodi water to your lfs and have them test it, something isn't right because that it really high. Since it sounds like you just got your rodi system I would suspect something is not connected right or there's a problem with your test kitThe salt has an alkalinity of about 10 dKh.

I fixed the problem, I was actually collecting the bad water, not the good.
Thanks for everyone's help!
