Ahh okay, no dosing of kalk water. I have been topping up the aquarium with fresh RO water not saltwater as the salinity increases slightly with evaporation and on a 57litre tank it’s noticeable - it goes up by 0.01 per day, so I have been topping up with fresh OU daily to reduce salinity.Magnesium of 1200 I don't believe would support a kh of 24. I believe Calcium and alkinity would precipitate out causing a crash of both alk and Ca. Your not dosing kalk water are you? Topping off with fresh RO water not salt water? I suspect, your alkalinity is fine, but, I would retest with a different test kit. Something isn't right unless your dosing something else...
If the Alk of your new salt mix is 21DKH than that is the issue. Doing a water change is not going to help at all.Thank you for your reply. My alk of my Marine Salt Water is 7.5 Meq/L and 21 dKH. No dosing at the moment although I do have all the Red Sea foundations to dose. I will lower my alkalinity now to 1.025...
I should mention I have a green algae issue at the moment comes back quick which I am treating with Red Sea NOPOX
I will rerun them now, and test the aquarium and RO water. It seems high coming out of the RO unit at 12dkh
A new test kit or get your lfs to test alk .Ahh okay, no dosing of kalk water. I have been topping up the aquarium with fresh RO water not saltwater as the salinity increases slightly with evaporation and on a 57litre tank it’s noticeable - it goes up by 0.01 per day, so I have been topping up with fresh OU daily to reduce salinity.
I will source a different tester, the Hanna test kit seems a good reliable tester - It did seem strange to me that I would have 12dKH coming out of the RO unit.
not dosing anything else, corals are not fully expanding daily, a new addition seems to be opening around a 1/4 while the other one which has been in there a while has not opened up today.
I would like to add I do feed my corals using the Red Sea coral nutrition. 2ml daily but I don’t think this would harm any levels?
If that were possible .I read that your salinity is 1.26 ppm and I’m confused. If you are referring to specific gravity, are you targeting 1.026 or 1.26? That’s a huge difference and would definitely juice your alk way too high.

exactly throw away the nopox stuff. It will cause red slime in all your tubing, filters and in your tank.] It happened to me in my 140 gallon.Stop dosing nopox if you don't have a skimmer. It will cause a bacterial bloom and suffocate your fish. Just use a phosphate test and some phosphate remover.
Should be around 7.5 but I am just running a new batch of fresh RO water and will test the alkalinity before and after adding the salt.If the Alk of your new salt mix is 21DKH than that is the issue. Doing a water change is not going to help at all.
I would get another test kit or have someone else test your water for you to confirm your results. If they are correct get a different salt mix.
Going in the bin now...exactly throw away the nopox stuff. It will cause red slime in all your tubing, filters and in your tank.] It happened to me in my 140 gallon.
The hannah phospahte tests are the best (they are digital). Salifert one is decent too. A lot of depends on how well you can see the colors. Avoid the API test as it doesn't go low enough.Thank you, I will cease using this now and source a phosphate test and remover
Your RO/DI should not have a DKH of 12! Something is very wrong there. I suspect you have your waste and product lines switched.It did seem strange to me that I would have 12dKH coming out of the RO unit.
lol I don’t blame you, I know my lfs sells the water, might be the solution once I test the alc with another test kit and if my levels are coming out at 12dkh from RO then it’s not doing a very good job at purify the waterThe only way I ever got high af dkh is when I used tap water + instant ocean salt , somehow my alk was 16 dkh! I just go to lfs for water now lol
O my days! I think you’ve cracked it! Just checked and I think I had them plumed in the wrong way around!!!!Your RO/DI should not have a DKH of 12! Something is very wrong there. I suspect you have your waste and product lines switched.
You’ve cracked it!! That is what has been causing this issue and my levels are generally that high!Your RO/DI should not have a DKH of 12! Something is very wrong there. I suspect you have your waste and product lines switched.
