Plants looking sunburned

[jsedgar]

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.

Are all the plants suffering or just certain species/individual specimens? While I'm here, the Swords and Crypts, were they floppy out of the water, or quite rigid?

Lateral why do the leaves on plants go brown?

It seems to be all of the plants that are suffering.
The Swords and the crypts were fairly rigid when I
placed them in the tank. I am going to start adding
C02 tonight. I think that is to much light on that
tank without CO2.

To be honest that isnt alot of light, the watts per gallon rule doesnt work on smaller tanks and certainly the light you have in there wont even come close to what the sun gives off so there is no where you'd be killing them by "too much light"

It could be Algae is ot looks liek somethign that ou could wipe of or if it is the actuall leaves that are turnign brown then they are dieing

perhaps a lack of iron... my plants looked thinned out and had brownish tips. the lady at the aquarium store told me to try plant tabs that contained slowly released doses of iron that lasts about 3 months. about 3 weeks later, my plants were significantly fuller and no new brown tips or spots appeared.

Add CO2 to the tank. You may want to lessen the amount of time that the lights are on. I have 65 watts over my 20L, and I leave the lights on for 10 hours a day. I also inject CO2. I think you've got plenty of light for the species that you're trying to grow.

Many plants, espeacially rosette plants, grow naturally in areas which are flooded part of the year and dry the rest. They have different leaf types for each environment.

True aquatic plants growing in submerged situations are floppy. They use the water for support. When the water goes away, they grow stronger "emergent" leaves.

A lot of rosette plants are commercially grown out of water, it is easier. When put underwater, they drop their emergent leaves and regrow their submerged form leaves. Thus, firm plants put underwater will expect to drop their emergent leaves and grow submerged leaves later, sometimes weeks or months later.

You say your plants were rigid, I'm guessing the place you got them from holds them out of water - is cheaper.

>>> Lateral why do the leaves on plants go brown?

If there was a "one size fits all" answer to that, I'd be a household name! The simple answer is that there is something either in, or lacking from their requirements.

In order, light, CO2, macro nutrients, micro nutrients.

Certains plants are outside of that general list, but get the light right, then get the CO2 right, then get the... etc.

I get what you mean lateral

L as in Litres or Long? I'm assuming Long, cos' if not, that'd be a LOT of light for a 20 litre tank...
