    Hello everyone,

    This is my first post on this forum, and I'm coming to ask for your help to help me to solve a problem in my aquarium. So, I have deficiencies on some of my aquarium plant, and I can't seem to know the cause of these deficiencies.

    I will therefore detail my installation as well as my flora, and my fertilization method.

    Light : 2x 50cm Chihiros Serie A (9600 lumens)
    Substrat : JBL AquaBasis + Manado
    Filtration : JBL e1502 + Juwel BioBox
    Co2 : JBL ProFlora u502

    I fertilize with the Estimative Index method, and I do water changes of 40% / week.
    My settings are:

    No3 : 20 ppm
    Po4 : 2 ppm
    K : 40 ppm
    Fe : 0,1 ppm
    Co2 : 25 ppm
    I also add Magnesium (MgSo4), but really a little bit, not having enough to test the concentration.

    Here is the list of plants:
    - Pogostemon Erectus, Alternanthera Reineckii Mini, Ludwigia Palustris, Rotala Vietnam H'ra, Micranthenum Monte Carlo, Bucephalandra sp, Anubia sp.

    And, photos :

    I also ask myself a question: my substrat is good ? Because I could consider doing a repair with ADA Amazonia ... but I await your opinions

    You did not mention the size of your tank, but I would consider running only a single Chihiros. Or dim the lights by 50% if you can, 9600 lumens seems like a lot. This will slow the plants down, giving you the time to optimize fertilizers and CO2. After things grow better you can consider increasing lights slowly again. It is also unclear to me if the ferts you mention are measured values or weekly doses.

    Good evening,

    Thank you for your reply.
    My tank is 240L (190L of water), 120x40x50.

    Infact I made my own LED ramp from two 50cm chihiros.

    The values are the theoretical nutrient levels added at the end of the week.
    After the water change, the No3 / Po4 are 10/1, and I increase them to 20/2.
