Ca deficiency?
The aquarium is still running very well, but…
The Nesaea crassicaulis is growing with slightly crooked leafs and the new Eusteralis stellata has similar growth, I dosed 10ppm Ca through CaSO4 at the latest water change, i hope to see some change in growth.
The Heteranthera zosterifolia seems to taste quite good according to my angel fish, all the leafs are chewed on, but as it grows quite fast it does not matter.
