limnophila aromatica

hey guys
any tips for growing this plant?

I had a few stems in the past but they just melted in my tank. there was always new growth but the bottom leaves would just slowly either away.

I want to give it another shot as I believe ihave everythn set with co2 and lights.

I have a 20 long with a finned ray 2 that is suspended over the tank 2-3 inches. ihave injected co2 and EI dosing.

What are some tips for growing this plant and how have you had success? Its a real nice plant and hope to get it to grow well in my tank

Thanks

Don't be afraid to trim close to the substrate. Periodically replant the tops, discard the bottoms. Give each stem a bit of space. Post pictures and enjoy

Post photos of the damage and we can go from there. Nitrate and phosphate readings would be helpful too.

I thought L. aromatica requires more light to do well as well as decent micronutrient dosing.

How long has the plant been in your tank?

It looks like the plant suffered from a lack of light (during shipping?).

In the OP picture there a lot of melting plants that should have been removed at least a day before.

The Aromatica in the foreground looks like newly planted young tops that came from low light tank.

L. Aromatica does pretty well in low medium non-co2 tanks, taking on lighter green color, still looking beautiful.

Lower leaves coming off is usually an indication that your CO2 is a little off.

This is not a CO2 (or Mg deficiency). It was either damage during shipping (too cold/hot/wet or a lack of light. You can tell because the damage is extensive - leaves all died and became gelatinous which is not the sign of a nutrient deficiency they also show uniform damage. Deficiencies are not quite as aggressive as this, nor do they affect so much of the plant.

CO2 deficiency causes no physical harm to the plant over the short term. The only change is plants stop growing, but all tissue is healthy. Some plants will show biogenic decalcification on their leaves (white precipitate) but no physical damage.

Magnesium deficiency is indeed in the old growth, but it is very distinctive, dark green veins will stand out on pale and chlorotic leaf tissue between the veins.

happi has a point, there are lots of deficiencies that affect old growth and we can't suspect them all just because the damage takes place on old growth. Looking at the pattern of damage helps rule out many of these issues.

While you don't need to, you can find out Mg levels by testing GH, measuring the calcium and subtracting the calcium from the GH reading (converted to ppm from degrees). GH is basically Ca+Mg. Appropriate levels somewhat depend on calcium, you don't want to have extremely high levels of magnesium and low levels of calcium as that can cause problems. A GH of about 6 is usually sufficient to grow most plants (and a 4:1 ratio of Ca:Mg seems to be the usual ratio between the two nutrients in most naturally occurring ground water).

you can also have Ca only and no Mg at all, this is true for my tap water. when you lack Mg plants do tend to loose their leaves, this starts from bottom of the plant and goes up. but, there are many other reason plants can do the same thing.
