Your Target Alkalinity DKH

[nervousmonkey]

Why 8 for lps?

LPS also grow skeletal tissue made of calcium and carbonate, but it's covered with more flesh.

 

[Rick Mathew]

9-10 dKH

 

[BCSreef]

SPS dominant mixed reef 8-9.

 

[WindeyD]

8-9dkh

 

[Eric Finney]

8-9 as well. Mixed reef SPS dominant

I use Red Sea coral pro salt and use there specs 11.8 to 12.7. I have great growth and color in my lps and softie tank.

28months ago, I started targeting as close to 7 as possible. If it goes above 7.4dkh then I make dosing adjustments. I have had less ( virtually zero ) issues since going to do. My tank is mature and don't care about trying to get that extra mm of growth. Most important to me is to keep corals from stn/rtn. Nitrates are typically undetectable. Phosphates in the morning are nearly undetectable ( they rise as high as .07ppm during day becuase of food but by morning its back to zero ).

Why 8 for lps?

A lot of my numbers reflect the salt mix I use.

I aim for 8-9...when I test...I need to invest in an alk monitor, but I'm waiting for the one from Neptune, GHL, or Focustronic.

@revhtree Should add a poll for this.

I try to shoot for 8dKH and have been successful. For a while I was running high at 12dKH, noticed faster growth but not so great color. Since I've dropped my dKH and started again dosing AA and coral food, growth is still steady but color is really coming out now.

Our LFS, Told my buddy to match his dkh to the salt he uses..

What is DKH

 

[GoVols]

8 - 8.5 dkh.
Why... My reef likes it.

What is DKH

It's a stupidly designed unit for alkalinity. lol

I thought it was just wasnt sure lol

My mag is high its 1400 how do i get it down some every thing els is good

That level is fine. It probably came in your salt mix.

The only way to ever lower magnesium is by water change with a lower magnesium mix.

Oh ok someone told me it was ok that it help on algee... what is a goid salt i use reef crystals

No worries, the next RC bucket will probably be 1100 lol
