Hi,

I posted looking for help on fertilizer not too long ago. I followed a suggestion and ordered KNO3, KH2PO4, and CSM+B. Looking at an email from Alan from aquariumfertilizer.com he talks about this

AquariumFertilizer.com's PMDD Formula:
1 Part KNO3 1 Part K2SO4
1 Part MgSO4 1 Part CSM+B

What am I supposed to do with the KH2PO4? Why didn't I order the K2SO4 and MgSO4? I don't think I need the GH booster, my tap reads at about 150 ppm GH, and about 40 ppm KH. Alan also states that the limiting factor is supposed to be phosphate (he put K2HPO4 next to the word, not sure if he meant KH2PO4 or not) when following the PMDD method, why would I be adding the KH2PO4 in this case? Can I mix these together or do I make one solution of KNO3 & CSM+B and then one solution of KH2PO4? Do I have what I need to cover fertilization for NPK and any other nutrients I may need?

I finally got my pressurized Co2 going yesterday and am almost out of my store bought liquid fertilizer. Thanks for any help. Oh and here is my previous post http://www.aquaticplantcentral.com/f...oduct-buy.html


Looking here it has a dosing suggestion. http://www.bestaquariumregulator.com/dosing.html
Do I need to dose the Iron even though I am dosing the Plantex CSM+B? Of course I don't like this as I like the idea of dosing daily amounts.
