ADA Hemianthus callitrichoides 'Cuba' Browning
This is my first time posting on here. I am fairly new to planted aquariums and I have a question about the state of my Hemianthus callitrichoides 'Cuba' from ADA.
Here is my setup.
Started with his setup at the end of last year.
Tank size : 90 Liter / 23 gallon
Filter : Eheim Classic 2217 good low and water agitation.
Light : Gex clear Led power III 900 - 23.5 W Not sure what specs to pull up.
Substrate: ADA Power Sand Advance / ADA Amazonian standard grain / ADA Amazonian fine grain on top
Additives : 2 x ADA bacteria balls under soil.
Liquid fertilizers - ADA Green Brightly Fertilizer Series. Currently using - Nitrogen / Iron / Neutral K / ECA Plus
CO2 Injection is used (drop checker is a dark green hue) and HC Cuba is 'pearly' everyday.
BIO Hemianthus callitrichoides 'Cuba'
BIO Cryptocoryne axelrodi
BIO Cryptocoryne parva
BIO Rotala sp. 'Vietnam'
BIO Ludwigia repens 'Super red'
All of the above plants are doing well, except the Cuba.
That said, the HC Cuba is growing a thick carpet, however there is some browning of leaves throughout the carpet.
I'm following the ADA instructions when it comes to fertilizing. But I think I'm missing something as there must be a nutrient deficiency.
Weekly water changes are performed. Usually 60/70% water change.
I do have 4 x Honey Dwarf Gourami
4 x Nerite snails
If you can help me out that would be much appreciated.
I'm based in Japan, so information is a little limited due to the language.
