I have mixed up some dry fertilizers(to liquid) to rex griggs specs. How often do I dose the liquid mix? every day?
Is my math correct that I would doze KH2P04 and Plantex CSM+b will be 1.041ml??Rex doesn't assume any particular dosing style on his liquid mix page. Assuming you want to dose EI-style, the basic dosing instructions are here:
But that's for dry ferts and larger tanks. So as Rex says in his gruff manner, here's where the basic math comes in.
If I recall correctly: You have a Fluval Flora, with 7.9G max capacity. Some of that is filled with substrate and driftwood, rather than water. You also have slower growing carpet plants, and plan to keep shrimp, which means we can afford to dose a bit lean. So, we'll take the 40-60G dosing recommendation and divide by 10, to give us dosage for a 4-6G tank:
0.05 Tsp-KN03 3x a week
0.0125 Tsp-KH2P04 3x a week
0.0125 Tsp-Trace (CSM+B) 3x a week
For the first one, you have 3 teaspoons of KNO3 dissolved in 250ml of water. How many doses is that in the bottle?
3 / 0.05 = 60 doses
And how many liquid ml is each dose?
250 / 60 = 4.166 ml per dose
But you may not have a ml measuring vial, so if not, type the following into Google:
"4.166 ml in teaspoons"
And it returns:
"4.16600 ml = 0.845215311 US teaspoons"
You should be able to determine correct dosage for KH2PO4 and CSM+B by applying the same steps. Try it. Post the result if you want and we'll proof it.
There is already enough potassium in both the nitrate and phosphate solutions for most tanks. So skip it unless you see signs of potassium deficiency; small pinholes in older leaves, bordered by yellow, that grow larger with time. It is to me the most easily recognizable deficiency.Is my math correct that I would doze KH2P04 and Plantex CSM+b will be 1.041ml??
and the 1/8th a teaspoon for k2so4
