Hello ,
I have some serious kh problems over the past 4 months my alkalinity stays above 14 at all time even after wc. But ph is 8.2
My wc water is 8.7 kh
And at this point I don’t know what to do or lower it

Have tested with
Hanna checker dkh
Salifert kh


Waterbox pen 25
Eheim 75 w heater
ICE cap nano skimmer
Cuprisorp media seachem
Kamoer ato 2
Red Sea reef led 50
Maxspect fx260 gyre ? With controller
Jebao slw 10

Tank has been running from Jan 2022 and in Jan 2023 I upgrade my tank form 40 l to 92 l with all the fish and corals , live stone .
Dosing : every week carbon switching
14 days rowa phos switch
4 days a week 40 ppm mg each time to kee euphyllia happy
Tropical marine all for reef 5 ml each day

What salt mix are you using and what are you dosing apart from all4reef?

Clearly this should not happen! Are you sure that you're testing the right way?

Cut back on your dosing until you have your alk under control.

Back off on the all for reef.. if you’re not dosing any alk or topping off with kalk etc the only thing that can be adding alk is the all 4 reef… I’m not sure what your nitrates are but all 4 reef does have a carbon source which brings no3 down and that can contribute to higher alk also. I’d stop dosing and continue your wc method and let it drop slowly and then start the all 4 reef back up at a lower dose. I’d also double check your test with a different one before doing anything else.

Double check your salinity. If that is creeping up, so will your Alkalinity.
Stop dosing AFR until you get the Alkalinity sorted out.

I am dosing atm 2 ml nopox a day spread over 6 hours each, then I normally dose 40 ml mg plus and will increase mg with 30 , I use ato but lately couldn’t use it much because of the dirty my filter sock was full in like a coulple of hours and that would drain the overflow chamber wich could harm the heater and the return pump .
Is it possible that I have to much carbon in my system that It plays a part in it ? ( dosing nopox Red Sea since 20 th July )

Stop dosing the all for reef and do water changes to bring it down slowly. What salt are you using? Some salts mix up at a high alk.
That is the thing I have a very good friend with like 2 500gallon tanks and she buys 1000 liters each 2 weeks and I buy if her the water ( ca 320 , 1320 mg 8.7 kh) and I don’t have the space or not allowed to have a large tank orso for rod to make my own water

What's your daily alk use? Sounds like you need to stop the dosing until you get back into range, and dial in you dosing based on your coral uptake.

Ph of 8.2 suggests that you do something to raise pH. Can you confirm or deny this?
Unfortunately my alk use is extremely low because of the few sps that k have don’t consume it and I gues because of the fact not optimal parameters .
But how do u get my paremeterd to stable because k want to start keep acro but at this point I need to wait atleast 2 months before buying acro

You achieve stability by not dosing anything that is not required, and simply letting the tank find its own balance.

At this point you should not be dosing AFR as it serves no purpose.

If your aim is for an SPS tank, you should be prepared to wait at least 6-12 months, otherwise you may well be simply wasting your money as they will likely die.

Chemical stability is not the only important parameter, the tank also needs bacterial balance and stability for those types of coral.
