Dwarf baby Tears are a fairly high demanding plant, as are most carpet type plants.
Meaning it will likely require fairly high lights as well as regular dosing of co2 and fertilisers.
Hemianthus callitrichoides 'Cuba'
If you click on the right hand side where it shows plant info and on the + icon, it gives out a tiny bit more but crucial information.
In the case of co2 it mentions -
"
CO2 : High
A medium need in CO2 is 6-14 mg/L. A high demand in CO2 is approx. 15-25 mg/L."
So that tells me if plants requires that amount of co2 the light demand will also be high as mentioned on the same site -
" Light demand: High
The average or medium light demand of an aquarium plant is 0,5 W/L."
Means you would need
over 0.5 watts of light per litre
This is becoming somewhat an old method of measurement now due to advancement of LED lights which is still pretty much in its infacy and improvements are continuing to happen).
But nonetheless you will still require lights thats above the standard or normal light units thats bought for the average aquarium in order to grow baby tears successfully. But belive me any lights that is above 0.5 watts per litre is a very bright light and algae issues can easily overcome the tank if you're not careful with the overall balance of ferts and co2 along with lights.
I have tried this on a high tech tank myself a couple of years ago with limited success but in the end I had to close the tank down due to algae issue, not an easy thing to keep a thriving high tech set up without a lot of time and research given but once successful and experience gained is a worthwhile thing to do.
