Yellowing/Dying carpet in new tank - High tech - 17 gallon
This is my first post in the forum. But I have been reading threads here for quite a while now.
Would love to get some advise on the 'problem' I am seeing in my new tank.
First, the specs->
Dimension-> 24*12*15 (same as ADA 60P, I guess)
Volume-> approx 15 gal effective
Substrate-> Amazonia, with a layer of the powdered variety on top of the 'carpet' area.
Light-> Sanrise LED, 39 watt (78*0.5W)
Filter-> Eheim 2215
CO2-> Pressurized, 2 bps approx
Ferts-> Tropica Specialized
Water-> RO mixed with tapwater (approx 150-200 TDS after mixing)
Photoperiod-> 5 hr with LED brightness set to 75%, since the tank is newly set up (2-3 days)
Fertilizer dosing-> about 1 - 2 pumps every day.
Water temperature-> around 28 degrees Celcius
1) Monte Carlo
2) Marsilea Hirsuta
3) Hydrocotyle Tripartita
4) Staurogyne repens
5) Alternanthera Reineckii Mini
6) Ludwigia Arcuata (or, Brevipes)
7) Heteranthera Zosterifolia
8) Anubias Nana Petite
9) Lilaeopsis Braziliensis
> It's been only about 2 days since I have planted the tank, so I might be getting too hasty. But wanted to get the community opinion anyways.
The problem is,
Monte carlo & Marsilea aren't looking that great. Lots of yellowing, dying plants in the bunch.
Here's a full tank shot->
Zoomed in showing the MC, it shows the yellowing to a certain extent. But I will attach better pics if necessary.
I had tried to plant all the foreground ones by separating the full bunches as much as possible, to the point where I was almost handling individual plantlets.
Additionally, the Marsilea came in its emersed form, which was rather tall. So, for the most part, I had cut them up and planted both the top half(the four leaf with the stalk) as well as the bottom half(the runner/root section) separately. Was this a mistake?
Also, I had ended up ordering too much plants, so I tried to fit them all.
Could this potentially be a problem? Is 'overplanting' a thing?
So, TLDR version:
> Newly set up high tech tank shows a lot of yellowing/dying in Monte Carlo and Marsilea Hirsuta.
> Looking for opinions/suggestion on the same. Is this just the plants trying to adjust from emersed to submerged form? Or does it indicate any deficiency?
Would really appreciate any advice y'all can provide.
