I use CSM+B but I prefer Flourish Comprehensive. So I didn't vote. I use CSM+B because I dose PPS-Pro and I couldn't decide on what was the appropriate amount of Flourish Comprehensive to use to be equivalent to CSM+B in dosing PPS-Pro. It was just easier to dose CSM+B so if I had problems with it I wouldn't be wondering if it was because I was using the Flourish.
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.
* Mix 2 tablespoons (30 grams) with 2 cups (473 ml) of water.
* 1 ml of this solution will add 0.1 ppm of iron to 10 gallons of water.
* 0.1 gram dosed dry in 20 gallons of water will add 0.09 ppm of iron.
* Suggested iron levels are 0.1-0.5 ppm
I dose CSM+B and flourish Iron at the same time since CSM+B seems to be somewhat lacking in Iron, flourish Iron makes up for that. I started doing this awhile back when I was testing my tank and realized that the amount of Iron in CSM+B was completely consumed by the plants within a half an hour of the photo period by subsequently adding flourish Iron you make more Iron available in the water column for a longer period of time thus yielding ore robust plant growth and coloration. even when i dose both all the Iron in my tank is consumed after a 6 hour photo period every time plants seems to take it up very fast
I have used a similar product as CSM+B called NutriSi here in Sweden. It seems to work rather badly in harder water and the chelate seems to denature very fast. I'm pretty sure it's not uptake but rather precipitation that makes CSM+B and NutriSi measure 0 levels fast after wc. Adding extra iron via Ferrogan every day made a huge difference, and then I moved to a HEEDTA-based micro named Mikro+ sold here in Sweden. It's kindof cool there is a low budget alternative with the same chelates as TMG.
I also use the PPS Pro method, which includes MgSO4 (magnesium) along with the NPK mix. I have been using CSM+B ever since I started growing plants (a little over a year), but have been doubling the dose of CSM+B for the last month or two.
I always attributed any green spot algae on my tanks due to my tendency to overfeed my fish. I will have to read up on gsa again.
I was not aware, excess iron would cause gsa, and I'm not sure I am dosing iron in excess.
Calcium? I never check or dose it as far as I know. I do have a kH test kit though.
