The other thing I learned is we’ll never obtain the perfect dosing regime because different plants react differently to the ppm’s in our aquariums.
You mentioned that I was not close to toxic amounts, but I’m thinking we need to have a term, say tolerance level, for our plants, because I believe some plants respond differently to certain ppm amounts. As and example, my monte carlo carpet really like the 11/2/18 recipe, but the HC hated it.
Well Ken you said you wanted this journal to be a discussion, and I think you brought up an excellent point.
IME, plant species react differently to changes in fert dosing.
Here’s an example. I recently lowered all my dosing (except Ca/Mg). Almost every single species reacted positively……..except Pantanal? So I PM’d Burr to get his thoughts. Interestingly, he has also been lowering dosing, and guess what? Everything seems to like it…..except Pantanal! We are both seeing very similar symptoms.
So now we are both trying to figure out what it likes more/less of. As I mentioned to Burr, I am going to go about it slowly, as I hate chasing one plant at the expense of others.
And sometimes it depends on how long/hard you want to bang your head against the wall. For instance, I can grow a “difficult” plant like Rotala Macranda Var. quite well, but struggle with S. Repens and AR Mini. Should I change things to please the ones I struggle with? I used to, but not so much anymore.
So I completely agree with your thought that there is no “perfect” dosing regimen. Part of the process is figuring what works best in YOUR tank.
I had a local laboratory test the water right before the last water change and right before I switched to the 12/2/18 recipe, out of curiosity to see what the results were. The test results are per below, with a comparison to my dosing amounts following afterward. Any comments or suggestions from all would be appreciated.
This is very interesting stuff. Haven’t had time to digest it all, but will give it a good look soon. I’m sure something to learn there.
What are your thoughts on the readings?
