Thank you very much for all the advice that could help me
. Here are more information about the aquarium condition.
It has been mentioned that the original photo is too saturated. It's because of the camera mode, not because I want to cover the algae which is less present.
Here I attach more photos in normal mode.
About fertilizer dosing:
I add every other day 2ml easylife profito, 2ml easylife fero, 2ml seachem flourish trace and 2ml seachem flourish phosphorus
. It is strange that the value of phosphorus in the water is zero (I use JBL tests that should be of good quality). However, I learned that the active substrate absorbs phosphorus into itself. So, I believe that phosphorus is present in the substrate.
A few days ago I planted the plant cuttings again.
Here's the current photo. Now it looks nice, but I already have the experience that the plants will go up again. Alternatera has narrow leaves and is thin. It looks unhealthy and dwarfed:
A few days ago I bought a new second light
, I hope it will help to lighten the aquarium better, especially the edges (on this photo is Alternatera before cutting):
There is another problem I am struggling with. Some leaves of plants have small holes, gradually glassing and falling. This problem is primarily affecting Hygrophila corymbosa 'Stricta' and Hygrophila polysperma.
Hygrophila corymbosa 'Stricta':
Despite these problems, I am generally satisfied with the aquarium status. However, I try to have a healthy and prosperous aquarium and still learn. I believe there is a mistake somewhere and someone will help me find it.
