Hi, I fell in love with Limnophila hippuridoides watching Tropica videos, but I have not had much luck with it so far. The only plants I could find for sale were tissue culture and not Tropica plants. I planted in to Unipac sand with Tropica plant growth substrate underneath. I am using pressurised CO2, I have had a few issues in the first few weeks with unstable CO2, but according to the Tropica site, this plant requires low CO2 and medium light, so I am not sure if my problem is CO2, or just a struggle to get the tissue culture plants established. My lights are a TMC 1500 Ultima tile, 6 hours a day at 20%, its also quite high above the water surface. The stems are at the back, so not bright light, but not too dark, its not in shade. I planted most of the stems when I bought it, but put a few in a propagator where it grows slowly. Most of the stems showed some new growth initially, just a fresh set of leaves at the top of the stem, but then the bottom of the stem just melts. I moved over stems from the propagator and these seemed to be doing much better, fresh growth again, but then the bottoms just rot again. These are only about an inch or so tall being tissue culture, so when the bottom rots, there is barely anything good left at the top to try and replant. I'm now down to a tiny group of about 6 stems which I am trying to keep alive, but worry that I will have the same issue again. I'm wondering if you know anywhere in the UK that stocks the Tropica version of this plant which is a pot and not tissue culture, so I can try and get more established plants in to the tank that might have a better chance please? Also any tips for growing this plant that might be useful for my next attempt to be more successful please? Thanks in advance!
