So I bought PMDD Pre-Mix from here:
For some reason I thought I would get individual packages of CSM+B and KNO3 and K2SO4 and MgSO4 for me to mix as I saw fit. Which is dumb because it is called pre mix.
Or maybe I thought that it would come pre mixed in ratios that would reflect the EI method or other recipes that I see around. They all seem to have much more Potassium Nitrate than the other Macros.
This mix says on the label:
Sears Conlin PMDD Formula
1tbl Plantex CSM
I don't know why a 1lb bag has 4tbs listed as the ingredients except if they mean 1Part of each of those things.
If they do I'm wondering how to dose this stuff.
Completely guessing I dissolved a teaspoon into 100ml and poured a third of it into a 20 gallon tank every other day for six days.
I immediately got an outbreak of BBA. I don't know if it was a coincidence or not but it sorta sucked. Throughout this time my NO3 remained at 0ppm where it has been since I started with the 3.25 WPG.
I've been looking everywhere for stump remover or Potassium Nitrate. I found it in blood meal or bat guano but they are not soluble.
I have a 20 gallon tank
65w of good spectrum light
DIY CO2- 6 bubbles per minute I don't know if I can trust my pH reading (KHd 3 pH 6.9) so I don't know exactly how many ppm, maybe 11
If I was willing to do the EI method (willing to do the water changes) how much should I add to the tank?
If I dry dose one teaspoon of the stuff that is pretty close to Rex's recommended 1/4, 1/4, 1/4 (leaving 1/4 for the plantex) for dry dosing.
Dose anyone think I need separate, extera KNO3 added.
