I used to have this written down but how much CSM+B and 11% Fe DPTA would I add to get a 2L stock solution if I plan on dosing 10 ml per day? The tank is 180 liters, not including filter or small sump.
Generally I mix 3 teaspoons:1 tsp and 1 tsp into 1 liter of hot tap water and 20 mls of vinegar(add vinegar 1st and shake for a few seconds, then add the Fe later..........), dose about 15-30 mls 2-4x a week. If your tank water is higher KH(say 6 or more), you likely can not add the Fe gluconate. Add more CMS or DTPA to make up for that.
Should I add some magnesium sulfate? My tap has no to very low gh and has a tds of 40... really soft. I add one gram of GH booster (from GLA) per 5 gallons of water when I change the water. I am not sure if there is magnesium in the GH booster or not.
