Add 1 liter of HOT tap water
3 Teaspoons of CMS+B
If you have DTPA Fe(uiron), add another 1 teaspoon of this.
If not, then add another Teaspoon of the CMS(So 4 tsp).
Wait about 1/2 hour then add about 5 mls 3-4x a week.
You can dose the same day(I do, always have), I dose macros 2x a week, you should too, basically after the water change. Traces also. Then maybe a day or two in between the WC's, add some traces.
Main thing now really is getting those plants really growing well and the CO2 dialed in really good.
After 2-3 weeks, shrimp can be added, otto's or a bushy nose pleco(babies).
Water changes will reset things and keep the tank clean and less CO2/algae issues.
