How are you supplementing calcium and alkalinity? I'd add nothing and let the values come down on their own.

What is the pH?

I was doing this:
Kalkwasser(drip mode)
Test kits are Salifert(expiration 2008)


*Seachem reef builder
*Seachem Advantage Ca
1/2 tsp on 1gal water twice a week,then switching every other week.(a week with reef builder then the other week Advantage Calcium the next week)
*water changes 10% every other week
*ph range between 7.8-8.0

I'd stop the Reef builder and Advantage Calcium. Maintain some limewater to keep the pH up, and let the calcium and alkalinity levels decline.

What salt mix?

Salt> IO
SG is always 1.025/.026 (refract)
Should I do a massive water change? ( 50% )
Limewater you meant a kalk drip?
Thanks
AJ

Kalkwasser is the german word for limewater, yes. I would keep doing that.

I'd have to say that I'm also skeptical about the calcium and alkalinity values, especially alkalinity.
Can you test the IO with the same kits and methods and see what you get?

results from IO :
ALK-4.5
KH-12.8

I don't understand how the values got to where they are, or why they are not declining rapidly, but a water change is a fine idea.

Water change like a 20%?
Should I do that amount twice a week,until it reach the expected results?

It will take quite a few 20% changes to bring those levels down.

What is in the tank now?

OK, then I probably would not do massive water changes. It will be a slow affair with 20% changes, however.

Thanks so much for the help,I'll keep you post it.About the water change,should I do one every week (20%) and test water on a 24hr cycle after adding the water?
Thanks

That sounds like a fine plan.

Good luck.
