Making a solution with dry ferts
For the last 8 months I have been simply dosing dry ferts into a cup, mixing, and then adding to the tank.
I now have 3 tanks and it will be easier to make a 500mL solution for my ferts. I have already done it with traces.
My question is:
Can I throw all the macro's into one 500mL bottle? Will they interact with each other and reduce the effectiveness? Will I be able dissolve all the ferts (kno3, k2so4, k2hpo4)?
I'm using YANC and it's telling me to 128.6g of kno3 to a 500mL solution so that each 18mL dose is 10ppm of no3 (I use a plastic pipette that is 3mL so it has to be multiples of that). I could use 12 or 15mL doses, but it says it won't dissolve. I wonder if water's capacity to dissolve an ion is based on an absolute basis, or an ion to ion basis? In other words, can I dissolve 126 grams of kno3 and 100g of K2so4?
