Feedbacks needed for a 2ft tank from a new kid on the block

[cowputer]

Hi guys,
Happy holiday.
I'm a new kid on the block here. I started the tank around 1 month ago and have re-arranged the landscape for 2-3 times after seeing those nice aquascape from you guys, and also partly to remove those non-aquatic plants that I unknowingly bought, or those demanding plants that melted in my tanks.

W/o further recounting on my countless failures, here is my tank specs, fauna and flora for your comments.
Will appreciate it very much if you can give me feedback on my layout (what to add, remove or re-arrange), or my fauna and flora to 'beautify' it

Tank Specs:
Tank Dimension: 2ft
Filter: Built-in Juwel internal filter
Light: 2x 24W (10 hrs/day 8pm-6am)
CO2: 2bps (11 hrs/day 7pm-6am) - some bros here advise that I should start the CO2 earlier than the light for maximizing photosynthesis result.
Substrate: 8kg of Gex soild and 8 kg of gravel
Temperature: around 28C with a fan
Fertilizer : Once a week with Sera fertilizer


Flora:
Mosses: Christmas, Singapore and Java
Carpet: HC, Hairgrass and Glosso
Others: Java fern, other don't-know-what plants

Fauna:
8 Tetra
4 Rasbora
4 Zebra Danio
2 Bards
10+ Cherry Shrimps
1 Otto
Gone: 2 Yamato (just gave away due to the destruction that they made on my carpet plant)
Will get soon: Some corydoras after my carpet is established.


Weekly ritual:
Change 30% of water (directly from the tap w/o adding any anti-chlorine solution)

Thanks for popping by and have any nice holiday.

Please do use aged-water and anti-chlorine! our tapwater isn't that friendly towards our little ones!
