Good Morning Guys,

I have a problem with the plants in my 20 gallon high aquarium.
I have Eco Complete substrate and a 65 watt Cora light plant light over the aquarium. The plants have been planted two weeks now. They include moneywort, red luwidiga, a few melon swords, and a bronze wendenti.

I am running the light 12 hours a day and No CO2. All of the plants look like they are burning on the top of the leaves. I am not sure if the plants I have cannot handle the light I have or if I am just missing something. I have never had trouble with plants in low light aquariums.

Anybody have any ideas of the problem. Or maybe a list of plants that would do better?

I'll be glad to give anymore information if you need it.

65W over a standard 20G tank is NOT low light. :wink: At this light level, CO2 is a necessity. Either DIY or invest in pressurized system is highly recommended. Do this BEFORE even taking a gander at the nutrients.

And in the meantime, until you do get CO2 going, reduce your wattage. Otherwise you're inviting all sorts of problems...

If by sunburned you mean pink, then add NO3. Or let it be if it looks nice.
