Hello everyone,
I am looking for help, as my Cryptocoryne keep dislocating, turning brown, etc. Which really annoys me, as I would really like them to be healthy. Reality is that I have had a number of plants over the years, different types of Anubia and some Cryptocorine aponogetifolia and have managed to kill most of them. Either the lighting is wrong or the water chemistry is off, as the fish definitely do not eat these plants. The fish are veryOK, it's just the plants that I really can't manage...
Mine is a 950l Tanganyika aquarium, with :
Fish:
Plants (grow in the sand, which has been in the aquarium a while, so should provide sufficient nutrients)

Mine is a 950l Tanganyika aquarium, with :
Fish:
- Tropheus moorii"Mpulungu"
- Ctenochromis Horei "Burundi"
- Synodontis mulipunctatus
- Tanganicodus irsacae"Ikola"
- Ancistrus
- Petrochromis trewavasae"Moliro"
- Neritina natalensis
Plants (grow in the sand, which has been in the aquarium a while, so should provide sufficient nutrients)
- Cryptocoryne aponogetifolia : 3 in total, one almost dead, the other 2 still alive, but not in good shape
- Anubia nana : dead...
- 2 Aquariusplant 120 (aqua-medic). LED lighting, each 10.000 lumen ie 21 lumen/liter
- pH 8.0
- Conductivity 620
- Nitrates 5ppm (very stable)
- Nitrites negligible
- Phosphates vary, but on the whole 0.2 to 0.8. I have increased water changes to ensure PO4 comes down permanently
- Oxygen is fine
- I have not tested CO2, but with quite a lot of fish in the aquarium CO2 should not be an issue
- I tested potassium 6 months ago and result seemed to be OK at the time (I think 10 mg/l)
- temperature 26°C
