brown ambulia
i have some ambulia in my tank, that was for a few weeks vibrant and green. now the lower leaves are turning brown despite it still growing like wild, new growth coming off the stalks, and bright vibrant bushy tops. i have API root tabs in the gravel, and the bunch has been separated so it gets plenty of light. how do ambulia take up nutrients? should i add a liquid fert or stick with the root tabs?

they were transplanted about 4 or 5 days ago, within the same tank, but they were starting to turn brown prior. lighting is 72 watts in a 20L, substrate is regular old gravel... i didnt feel like dealing with the mess of the plant substrate i had in there before :)

You mean Anubias?
2 things strike me there...why root tablets? If the Anubias not attached to driftwood or rocks? Won't thrive well if its buried in gravel. Hence the fact you'd not need root tablets, they're liquid feeders.

72 w on 20L(=5g) is hardcore overkill man! Dial this down to like 15w or less!!! You're literally melting your plants with this light.

I am assuming that by "Ambulia" you mean the cabomba-like stem plant, Limnophila aquaticum. Or if the "Asian Ambulia", Limnophila sessiliflora. Photos attached for reference.

It does like high light, so while I agree with Angel that there is excess light over this tank (and that means other issues) it should not have been the cause for this plant's poor growth. However, with more light come more nutrients including CO2. As for mineral nutrients, substrate fertilization would be of minimal benefit with this as other stem plants which develop roots along the stems and assimilate nutrients via roots and leaves. Liquid fertilization is best for stem plants. According to my colleagues at the planted tank, it will grow well even in less light without CO2, so I would suggest lowering the light intensity and using a liquid fertilizer to get the nutrients and light in balance.

Limnophila indica, actually, according to, where i got it from.

I'm sorry beetlebz....I honestly didn't know Limnophilaalso ran under the name "Ambulia" never heard that before to be honest...I thought you simply misspelled Anubias...My bet sorry for misleading you.

This species is near identical to L. sessiliflora. Photo attached. Similar requirements. B.
