Plants need the following elements to grow:
Macros N, K, Ca, Mg, P, S
Microns Fe, CL, Mn, B, Zn, Cu, Mo, Ni
You are dosing NPK and Fe, Mn, B, Zn, Cu, Mo, Ni. You are missing Ca, Mg, S and Cl. Your water quality report shows you have very soft water with minimal Ca, Mg, S. Cl levels are sufficient in your water quality report.
Seachem Advanced mainly contains a bunch of plant hormones that will only supply carbon, and a small amount of Ca, Mg,
You might get better plant growth by boosting your water hardness by 2 digress with a GH booster such as Seachem Equilibrium.. This would supply a lot more ca, Mg, S,K. You would also be better off splitting your iron dose into 4 equally spaced doses per week (The main ingredient in Seachem iron doesn't last long in the aquarium. You also might get better results with Nilocg.com Thrive (regular version) since it is more concentrated in micros and includes your macros. Also the iron in Thrive will last longer in the tank. Keep using Excel. Thats 3 bottles verses the 6 you are using now.
Thanks very much for your reply. Im happy you were able to access my water information and tell me what I am missing and what I need. I have looked at my report, but I was not able to determine levels beyond the most basic information.
I forgot to add that I am using Seachem Equilibrium as well after recommendation from here. It has been a couple of months and, now that you mention it, a month after I began dosing the Advance. It may, in fact, be the Equilibrium that is giving me better results with my anubias and java fern and not the Advance. However, my stem plants continue to struggle or grow slowly,-but, I think this is due to lack of Co2.
The Nilocg is liquid like the Seachem line? I realize that the premixed is more expensive- but, I dont want to bother with mixing and calculating- I do not have time. Actually, even if I did have time, I dont want to.
So, let me say back to you what I think you are saying would be best for me: Continue using the Seachem Equilibrium, change from Seachem line to Nilocg ( All-in- one), and continue using Excel.
Again, thank you.
