I bought some CSM+B but it didn't come
doesing instructing so i sent them a e-mail about doesing... this is the reply
All store bought micro nutrient solutions are between 94% and 97% water, by weight. If you have a decent scale...accurate to a tenth of a gram... you can create an exact copy of Flourish by adding 6% CSM+B to 94% water. As a single milliliter of water weighs 1 gram, for 500 ml of solution you would add 30 grams of CSM+B. A fun calculation is grams in a pound - 454 - divided by 60 = the number of liters of solution you can get out of your pound of CSM...7.5. 7.5 times 2 times $8.00 (the average cost for 500ml of Flourish) = $120. Flourish costs 10 times as much as CSM+B!
Anyway, back to your question. For a solution like Flourish just add two tablespoons of CSM+B to 500ml distilled water. Keep in the dark, use within a month. PMDD instructions can be used, along with many other dosing strategies. For PMDD solution use only 1 tablespoon to 500ml distilled water. Our dosing stratagem is PMDD based - 1 to 4 drops per gallon per day. 20 drops equal 1 ml. So for a 50 gallon tank you would use at least 2.5 ml, and no more then 10 ml per day. That is for a tank with CO2. For a tank without CO2, 5ml would be the maximum we would recommend.
May your tanks glow green and bubble!
