too much light bad for anubias?

[stonedaquarium]

hi there i just noticed my anubias leaves dying... which is pretty odd... i got some anubias nana which i placed a bit close to the surface as i attached it to the drift wood and now i see the leaves starting to develop holes and rot away?

could this be from too much light? i know anubias are low light plants but could too much light be the culprit?

How much light are we talking about? Are you dosing any ferts, CO2, etc? The more info we get about the tank, the better...

 

[stonedaquarium]

3 wpg and dosing seachem potassium, iron, nitrogen 3x a week and flourish trace 2x

 

[stonedaquarium]

also using pressurized co2

3 wpg of what type of lighting and in what size tank?

 

[stonedaquarium]

20 gal
3wpg (2 x 24W T5 HO 6500K and 1x 15W T8 6000K )

Way too much light for a 20 gallon. You can't go by wpg for T5's, that rule was thrown out long ago. For anubius, you can scrap the T5's and just use the T8 on that tank, not sure what others plants you have in the tank tho. I have anubius growing in a 2g betta jar with ambient light only, in a year it went from a few leaves to over 15.

i got a lot of plants in the tank. rotalas, wisteria, cabambas, java ferns, java mosses, glosso, riccia, crypts lucens and another crypt.

Can you get pictures of the leaves?

That is a lot of light. What tends to happen with Anubias in extremely high light is that the leaves turn dark green. This isn't the plant getting darker. It is algae overtaking the plant of smothering it. The plant then starts to show symptoms of nutrient deficiency.

Also keep in mind that the number of plants doesn't really affect how much light you need. If your most demanding plant can survive off the T8, then you only need the T8. Sounds like this is a 20 Tall though so the T8 alone may not work. The T5HO is still very high light though and can make life difficult for low-light plants.

A little much on the light, although I probably wouldn't recommend cutting down to just the T8 with some of the plants you do have...try just the T5s for now.
