How do i lower my alkalinity

[big man]

I checked my alkalinity and it was around 14.4 dkh. So far my coral and look fine. But I want to know how I should lower it. So it goes down to 10-12. Should I use a non reef crystal salt.? The test kit I used was salifert

I'd test again, maybe with another kit. What it your new SW Alk?

Agreed with above. Unless you're dosing or your salinity is wrong, alk can't get that high.

Never say never...

My salinity is at 1.024 and I just got the salifert test today. I dont have any other test kit. Also I don't have an rodi system so I use tap water and water conditioner. The salt im using is regular instant ocean sea salt cause had some left over and i ran out of th reef crystal salt. I tested it again and it still shows the same readings

More then likely your TAP water has some alkalinity in it, which is adding to the ALK of your mix. Unless you stop using TAP, your alk will not go down until it is consumed.

Reef Crystals is pretty high in alk. What is in the tank that uses alk?

What about coralline algae?

What about coralline algae?

Yes I also have a good amount of coraline algae on my rocks

I'd just keep monitoring the alk and stop using tap water for anything, if you can.

If you cannot, you can buy a chemical to lower the alk in the new salt water:

Sodium Bisulfate to Reduce Alkalinity in New Salt Water or in Display Tanks

I just want to record these calculations in their own thread to refer back to in other threads. When alkalinity is too high in new salt water or in a display tank, acid can be used to lower the alkalinity. You can easily use muriatic acid (hydrochloric acid), or sodium bifulfate (e.g...
