Day 168 "Metaphor": Blyxa Japonica Removed, Ludwigia Red Added, Monte Carlo Recovering Nicely

Phosphates 
I continue to dose high amounts of KH2PO4 but test kit shows I'm still shows 0.5 mg/L at best. There's been consistent improvement with plants so that's good. Maybe I should consider reducing it next week, probably around 10-15 mg/L.


Trace and Iron Dosing
I measured Fe before dosing anything in one afternoon and I got 0 mg/L. Then I dosed 4 drops of Rexolin APN liquid which is approximately 0.2mg/L of its powder form. With that dosage, I should get at least 0.1 mg/L if my bottle concentration is 100g/120mL. I measured and indeed found 0.1 mg/L! It might be true after all that the concentration of this bottle is as accurate as it says.
However, when I dosed 0.4 mg/L, I'm able to measure only 0.1 mg/L in the tank. Is the soil absorbing excess Fe to limit it to 0.1 mg/L just like phosphates being limited to 0.5 mg/L?


Monte Carlo
Monte Carlo carpet has gone through major trimming last week. I left the back lawn untouched. It is growing well without a problem. After a week it grew nicely. It's still a few more weeks to go before the lawn gets thick and lush but it's on its way there. No more new growth in bad shape.
There's very few older leaves that melted but it's not so bad, still will keep a look at them. Some very old leaves are not as healthy. Their color is dark green. Are they just really healthy? Were they covered by top leaves and are deprived of light? Are they covered by GSA? Not sure... Any ways, here are some pictures.

Middle front starting to grow nicely

Right front corner growing nicely as well

Back lawn spreading

Ammannia Bonsai
Not sure what happened in this plant. There were 4 original stalks planted. About a week or more It has established itself and growth is slow but good. Then I trimmed and replant. Now, all trimmings are gone, and the original 4 are dying... it's in the corner of the tank with poor circulation and CO2 so there's that.
What's interesting is I planted one stalk from the original pack in the Discus (Low-tech) tank. It's growing fine but very slow. I rather not touch it though.

Ammannia Bonsai melted for some reason so I put some MC trimmings in their spot instead

Blyxa Japonica Removed
As planned, I removed this plant in order to give room for Staurogyne Repens and AR mini. Those two are the plants that I'm not able to grow consistently nice. This time, I'm placing them in the best spot to grow.

Ludwigia Red Added
These are trimmings from my an old plant in the  Discus (Low-tech) tank. It's in bad shape and I'm hoping it recovers here and grow well.

And finally, the tank's latest shot...
