I up my Mg from 9mg/l to around 15 mgl. Ca is 40 mgl (I personally think that Ca is rarely the culprit in bad Ca uptake, in my survey on 33 weeks it never went down 40 mg/l)
My ludwigia that was almost dead and crinckle have new growht almost perfect, she’s coming back to life, Elodea growing fast and nice. everything seem better. Some pearling even on the dead old ludwigia leaves. Even some java fern that was dormant for more then a year came back to life.
Not sure but Rotala indica is beautiful but seem to slow down a litle bit on growht. (less side roots)
I’m adding Potassium at 16.5mgl (as my survey show). This the only part that I cannot test, I just go with the flow.
I wonder the rate of potassium uptake in a well lit, co2 tank???
I want to lower my Fe (traces) to .2 to get a small amount of GSA, GDA at bay...
Another thing My phosphate seem to went up by itself, I need to look at number on this one...
