A suggested EI macro dose is 7.5ppm NO3, 1.3ppm PO4, 7.5 ppm K
The dose of NO3 & PO4 provides more than half of the K requirement before adding K2SO4.
Not picking here just trying to understand everything you are adding to your tank.
This reply is for you and @Greggz
both of you made me go back and look at my notes and I appreciate that.
That tank is looking very nice for no CO2, so well done.
And if you learn how to state your dosing in ppm's per week, it will be easier for others to help you. Very few will go calculate each, and ppm is the universal language spoken here.
You seem to have a lot going right, so I wouldn't change anything too abruptly. And only change one thing at a time. I would try cutting out the extra K for two or three weeks and see what happens. Then you can go from there.
Ty both kindly, ty you greggz for the compliment
, there's a few plants that won't grow, Wisteria, water sprite and my Amazon sword do horribly and my anubias is still recovering from equilibrium burn so I have no idea why those plants don't grow.
What do you mean by learning ppm dosing?
Like posting the details of all the nutrients in the ferts? I know all my tanks parameters.
I do know how much NPK each dose adds I just didn't know if that would just frustrate people so I apologize, also didn't know I add the 3 nutrients up together
Yikes I see what you're both saying saying KNO3 at what I'm dosing adds 6.31 ppm k the KH2P04 is about 1ppm so I'm actually dosing approx 17.31ppm K yikes, thank you and I will definitely cut out the K2S04.
If I'm doing it right as I was told I dose for actual water volume not tank size, what im dosing (taking K2S04 out if the equation)
KNO3 adds 10 ppm NO3, 2.26 ppm (N), and 6.31 ppm (K)
KH2P04 adds 1ppm PO4, 0.33 ppm (P) and 0.82 ppm (K)
As far as breaking it up into 2 doses I do that with my macros so I have a constant value in the tank throughout the week, so again if I'm doing it correctly as I was also told to increase my PO4 by one I take rotala dosing for low light weekly and cut only the KNO3 in half, 2.78 for total per week (i dose 1.4 grams 2x weekly) and dose PO4 @ 0.312 grams to reach a target of 1 ppm PO4 and dose that amount 2 times to get closer to 2 ppm PO4
As far as micros it's to tedious to dose such small amounts 2 x so I just dose that one time per week.
Should I just do the whole doses 1x a week instead of dosing KNO3 at half the dose 2X?
Is it true that you want to match your K to your N? Or is that really only for high tech, I dint want to frustrate anyone I was just wondering is I should say calculate for approx 3ppm extra K from the K2S04 or as @Greggz
mentioned cut that out for about a month as I know it takes a while to see differences now.
Would that high dose of K limit plant growth? Which would be why the hair algae is still a nightmare
, I am aware the key to beating algae is healthy plant growth, ty Both for making me go back and relook at my notes and relook at the ppm each nutrient adds.
Yes DTPA 11% is what I use as my pH is 7.5-7.6
I just complicated myself totally so hopefully I didn't complicate the post to much and you both try to reach through the phone and strangle me
, I'm horrible at typing things out.
