Confused on what to do with DIY fertilizer! I need some help!

I am thinking about going to get some KNO3 and some trace elements. I did my research on thekrib.com. I will follow their reciepe. But I don't know how to dose. I have a 66 gallon tank, and I have CO2, although I can't seem to get around ten for CO2, which is the lowest of the good I can get. I have a high pH (7.5) and a high KH (70ppm)

Does anyone else have a dosing preference, or their own reciepe?

Thanks

Joel

How much of each nutrient should be dosed, depends largely on the plant mass and
lighting in the tank. You will hear the word balance a lot on these forums, and
that's mainly what they're referring to when they use that word.
My advice is to start dosing individual ferts. (N,K,P and Traces) and see how your tank
and plants respond.
Also, depending on the lighting, 10ppm/CO2 may be enough for your tank.
To learn more about planted tanks and dosages go here:

You will see a lot of articles that will be very helpful to you and are great references.
You will also see a link for a desktop calculator that will assist you as you learn how much of the nutrients to dose. Follow the suggested dosages on the calculator and then you can add or subtract to your individual dosages. Then after you learn what your tank's plants will use, you can make up your own 'recipe' for your tank.
Start by dosing on the light side, rather than jumping in with full dosages from the start. Your plants will tell you if they need additional nutrients.
I always suggest to people starting with plants, to load up on them. Especially the Stems and other nutrient users.

I only have one stem plant, will the root feeders benefit somewhat from the ferts?

Mine do. I keep many different varieties of Crytocoryne and some Amazon Swords, and have never felt the need to use root tabs at all.

By "only one stem plant" do you mean one plant or one type of stem plant?

If it's only one plant in a 66g tank, you don't need to fertilize NO3 or traces.

Also, a pH of 7.5 isn't 'high', and 70ppm of Kh isn't 'high' either. My Kh is about 140ppm and I have zero issues using pressurized CO2 in my 75g, and DIY co2 in my 20 gallon, of reaching 20-25ppm of CO2.
I just wanted to clarify that.

Ok I mean I have only one type of stem plant in my 66! Sunset Hygro, some people say you can't kill it, but it is dying so fast now. It is just starting to come back. I might want to add that I have 2.5 wpg of light on the tank.

Thanks,

Joel

sunset hygro grows like a weed if you have strong enough light. you typically need 2.5+wpg to get the pink to show up.
