This is a discussion on my plants are turning red within the Beginner Planted Aquarium forums, part of the Beginner Freshwater Aquarium category; -->
the older leaves on my egeria densa are turning red, ... then they fall away :(
does anyone know what could be going on ...
What temp is it kept at? Most of the Egeria densa available prefers 'cooler water' and will just melt if it is too warm. There is a Brazilian variant that prefers warmer water but it would appear (from your description) that it is melting due to the temp.
i'm not very familiar with the "melting" you talk of.
i do know first the leaves are turning a very distinct red, starting at the tips & edges till the whole leave is red, ... longest stretch of leaves is about 4" long, ... from newest growth to oldest leaves.
