Struggling Monte Carlo - need advice

[Tedrock]

I have some struggling Monte Carlo plants can you help?  They have melted back or seemed to dying with little or very little new growth.  They are a month old from the coop and I have just placed a second root tab in the rock wool.  The tank had CO2 and is allowing for some pearling of other plants.  I placed the plant in the plastic in eco complete substrate in 80 degree water that has some hardness and no ammonia.  Ph is neutral as well.  The tank is a 32.5 gallon Fluval with and aquasky light set to 10 hours of varying light intensity.  Your thought are appreciated.   Tedrock.

I would remove them from the pot and place them in the substrate. I would check CO2 levels and make sure you have enough. I would also stop using root tabs with Eco Complete and look for a comprehensive fertilizer to dose the water column. 

What hardness is the water? What is the KH? 

Can you take a picture?

@Mmiller2001why wouldn’t you want to use root tabs with Eco-Complete? 

[Mmiller2001]

That substrate is too coarse and the tab will leech out rapidly often spiking nutrients and causes irregularities that can be difficult to navigate.

Oh boy! Thanks for the heads up I just added root tabs in Eco-Complete about a week ago! I will keep an eye on it.
