Does anyone know why some Cryptocoryne pink flamingo reverts to non-pink? Any way to prevent this?

Noticed my crypts losing their pink color and the only difference I can think of is the lack light. This tank gets exposed to sunlight, and during late spring and summer the crypts were a vibrant pink. Can high light bring back pink coloration?

Short answer is yes it's probably light.

Longer answer is that it could be a nutrient issue or a combination of nutrients and light, and/or co2 as well. But if you had it for a while in your tank and it turned pink when you had more light (and not that it was brand new) then it's likely a lack of light keeping it green.

Nutrients should be fine. Using nilocg tabs and liquid ferts. Must be the weak light. Guess it's time for an upgrade.
