How to reduce dKh?

[PowderTang]

My dKh level is rather high...about 15

How do I reduce it and will the high level affect myLPS ?

[Clement Chen]

Wow that is high, have to do more water changes and let it drop on its own..

[tofubox]

+1 on water change. Only way it seems.

[Yxh]

Use reliable test kit to measure again before u take any action ..

[youdontnowm]

Wc with low kh salt like skimz salt or red sea blue bucket salt or tropic marin.

Stop dosing any kh supplements.

I had this problem when I first started out my new tank... It slowly balanced out on its own after 8 weeks...

I using salifert to test and Red Sea salt that says kh 7.7 and alk t2.8 meq/l

Have been doing 10-20% water change twice this week with NSW

Won't go down

What makes it so high ? Used to add strontium, calcium, magnesium and pH 8.2 buffer, that's all..

Now I stopped adding any...hp I wonder what makes it so high?

Will it affect my LPS ?

Thanks

Forgot to add, My Ca was used to be above 500 so after do water change, it dropped to normal... Now just found out kh is high....

[Nox]

wow 500 is very high, did u over dose?

i think wc is the only way to bring down the levels

[PowderTang]

Ok I realized why it is high It's because I increase the pH using pH buffer. Yes now kh is reduced during water changes...but then I test pH again, pH dropped to like 7.8 ! If I increase the pH, the kh will increase again Anyone has come across this problem ? Or is there anyone with pH above 8 and yet kh is normal ?

[Nox]

My kh is at 9, ph varies 8.1-8.3. Kh and ph will increase together. For me the easiest way is to dose the 2 part solution (eg c-balance) to bring your ph and kh to the ideal level, no need to dose ph buffer. You can also try using kalk to increase ph and Kh together

[tang_sohal]

Can try dose kalkwasser which is around ph 12.4. it will help bring up your ph

Setup dosing pump , but u need expert guidance , I'm no expert , hopefully some pro here can guide u how to set up dosing , by then water parameter should be balance ...

[Guest]

Try to do a major water change and it should solve the chemistry imbalance problem.

[sherman]

Or just stop your kh dosing. But must monitor with test

[PowderTang]

Never dose kh before but did some pH buffer, so that's why kh shoot up Anyway I did major water change Liao and kh dropping

[PowderTang]

My kh is now 9, is it good enough ? Wads the ideal parameters for reef tank ? Thanks
