I wa able to grow this emersed a few years back (it took over the tank), however since then I haven't been able to keep it alive (beyond a few weeks). Has anyone got any advice on how to grow this?

I have soft acidic spring water. One tank with co2, the others don't use Co2. I tend to provide a nutritious substrate and use lean dosing.

Hi @Onima1

I have it growing quickly in my low-energy aquarium. Light is low and the water is moderate hardness given the stone I have in my aquarium. I have to supplement magnesium.

I use @Burr740 macros and micros. Macros are front-loaded once a week and micros dripped daily.

All of mine are growing as epiphytes. Do you have yours planted?

I have just 'planted' a pot of Dennerle, in one tank within crevices in a rock and in the other into a fairly inert area of substrate. I will review my fertilisation regime. Thanks for the tips.

I have some growing in my hillstream tank. It’s doing well, planted in the substrate, which is 2-3 mm sand/gravel. It’s low-tech, 40 par (80 par for a few hours), dgH 9, dkH 2, pH 7.

It sounds like it does well in slightly alkaline or neutral water. Mine is quite acid with a Ph of 5 (ish). Perhaps, that's the reason. My water is drawn from a spring with the surrounding land being peat moorland. The acidity of the water can vary over the year (dependent on rainfall). Given most of the fish I keep are from amazonian blackwaters or areas where the Ph is low (and varies across the season) fish seem to thrive and I haven't had to remediate. Most plants seem fine with this.
