Buying Carpet Plant with Shipping Expedition 3-4 Days

[KevinZ]

Hi!
So I always trying to cover my gravel substrate. But I can't find any Carpet Plant near me. And all I can do is Buying it Online. And the fastest Shipping Time is 3 Day!
I tried to buy Monte Carlo and it's a waste. All of the leaf already melted I can barely touch it without destroying the monte. So I don't plant it at all and throw it away. And last week bought Saggitaria subulata and Arrive 2 Days ago. Most of them already Melted, and I tried to plant it since there's 1-3 Leaf Left I don't see any improvement today. All I see is the plant is getting worst.
It's 50 Gallon Tank
Water Chemical
GH 7
Ph 6.8
Temperature 22 Celcius
I haven't check Ammonia nitrate and nitrite yet.
I use Co2 Tablet since I can't find any injection replacement for my Tank. (I might make Yeast & Sugar DIY tomorrow)
Tropica specialised nutritions Fertilizer.
Any Suggestion? Should I keep going and try to growth the SS or should i remove them?
I am pretty sad bc I have never successfully growth Carpet lol (Exception for My Java Moss Carpet On Shrimp tank )

If it appears there is any life left, I would keep the plants. The ones in the pictures look like they might make it.

Yes, but that's the best one. The rest? Oh no no,
Either Turning Brown/Yellow/Rip Leaf.
What's upset me more is that my upside down catfish didn't touch my cabomba or any stem plant But keep uprooting my SS lol

Stop buying plants online unless they can guarantee a 24 hour delivery.
