What do I do about Phosphate
So I just order dry fertilizers from aquariumfertilizer.com and they have a macro micro premixed package of Potassium Nitrate, Potassium Sulfate, Magnesium Sulfate, Plantex CSM+B. So I bought all of these but as single lbs so I can alter the mix later if I want but after ordering I noticed that their missing phosphate. I will be using them with EI, my tank is well established so their should be some P but i dont have a large bio load. I am afraid nutrient imbalance might create algae if I start KNO3, K2SO4,MgSO4 w/o any P
Should I buy a lbs of mono Potassium Phosphate and wait til it arrives to start fert? Or is it ok b/c the P ppm need to be so low anyways?
Or am I just totally wrong about the P, I would expect it to be in a macro/micro package? no..
