Hi all, this is my first post so i hope I don't babble on too much...
i've been into planted tanks for a few years now but i've always kept the ferterlising simple, i think its time i started dosing dry powders.
I will base this on my 120L, i currently dose TPN for trace and TPN+ for my macros, i alternate a 3ml dose each day, co2 is pressurised and stable at 30ppm, photoperiod is 7 hours from 2 T5 tubes and i occasionally add TPN capsules to the substrate.
I have never dosed iron and i dont think its a ingredient in tpn or + so this is a obvious defficiency, other than that i guess i need to dose Potassium Nitrate and Potassium Phosphate but i have no clue how much and how often...
Also my water is very very soft, KH and GH are pretty much un-traceable with standard kits, does this mean i will have very low amounts of calcium and magnesium? If so is it necessary to dose these and if so how much?
I'd like to use powders in conjunction with tpn and tpn+ and despite days of research i'm still not sure exactly what to dose or how much and how often - this is why i need the help of experienced members. Any guidance that you can give would be a huge help to me.
Thanks for taking the time to read this.
