Hello from the USA. I have come here from the recommendation of Happi.

Setup is as follows:
50 gallon aquarium running on 20 gallon diy sump.
I have fluval 3.0 light
Black Diamond Blasting sand - Medium grit
Target 4 dGH - 0 dKH
Co2 injection targeting 1-1.2 drop in PH
Estimate 54% weekly water change with Macros front loaded.

Fighting BBA for a long time.

I was dosing CSM+B daily for Micros, but switched to Topica Premium Nutrition dosed daily for Micros.


I have been switching over from low tech to high tech the past 4 weeks or so.

This was my starting point into dry ferts.

I want to get away from dosing sulfer. So I switched the MgS04 for Mg Gluconate and K2SO4 for Potassium Chloride. Did my normal water change yesterday and today when I got home form work. I have cloudy water. This is my first time with cloudy water in years. Something to note. I dosed the tank on Saturday with API algaefix

Cloudy 50 gallon after switching to Mg Gluconate and Potassium Chloride. Water was clear right after water change and the rest of the day with Co2 injection.

Skipped water change on the 30 today due to cloudy 50 gallon.

Hi @Nooch If the cloudy water just happened on the first occurrence after switching in the Mg Gluconate, its probably safe to blame to Gluconate. If so, the water should clear up in a couple of days. At your next WC I would cut the Mg Gluconate amount in half and compensate with MgSO4 to reach your Mg target (i.e. 3.2 ppm of Mg Gluconate and 3.2 ppm of MgSo4 to reach your goal of 6.4 ppm) . It's not clear to me if the reaction is due to precipitation, bacteria bloom or something else. I just kept lowering the Gluconate amounts until the water stopped getting cloudy after the WCs. In my own tanks, I am right now getting 2/3rd of my Mg from Mg Gluconate and 1/3rd from Mg(NO3) (which covers my N/NO3 target as well).

Welcome to UKAPS! :)

Cheers,
Michael

it could be related to Bacteria bloom because Gluconate is sugar and bacteria love this stuff. but it could also be that too much Mg gluconate isn't fully soluble depending on how much you add.

@Nooch

you can also look into using different source of chemicals to make your GH booster, members of this community can help answer all of your questions.

Hi Michael. Thanks for the response. It seems it must be the Gluconate. Not sure what direction I'll go from here, but I do know I want to reduce the So4. Maybe I'll just keep doing WC's until its sorted out. I'll also look into cutting the Mg gluc with some MgNo3.

Very interested to find a Ca source without So4 or Cl. CaNo3 is not an option as I dont dose much N/No3 due to fish load.

Hi Happi! Where do you source most of your salts/elements?

Hi @Nooch take a look at this thread Lowering TDS.
