Alkalinity issues please help me

[Rickybobby]

I’ve looked around having a hard time getting an answer. I don’t have rodi right now I’m in the country on a well. My alk is measuring 16 out of the tap!!! Is there anyway to lower alkalinity ? If so what to do? I’m thinking this is why some of my corals are not happy

 

[Aaronreef]

Are you using water from the tap directly no filtration from a RO unit?

 

[hmmmmm]

Get an Rodi unit with a pump?

 

[Rickybobby]

I don’t have rodi at the moment

 

[Rickybobby]

I have a Red Sea test kit if you put 5ml of water in than one drop is 1 dkh right?

 

[Aaronreef]

Ok so what other chemicals and hard metals are in the well water your using

 

[Rickybobby]

Do you guys think that this dkh is why some of my zoas aren’t open? But weirdly enough there open in my display tank

 

[Aaronreef]

I'm not sure about red sea alkalinity test kits but even at 16 dkh I'd imagine that water your using has more than alkalinity issues

 

[Aaronreef]

A dkh of 16 is extremely high yes what's the dkh of the actual tank?
I'd still be concerned about the other stuff in that water your using

 

[Rickybobby]

Can someone reccomend me an rodi unit. I’m in. Canada but a lot of places ship to Canada. My tanks are all nano so I don’t need large volumes

Any RODI will do probably 50gpd will be sufficient you might need a booster pump if you're water pressure is low
