I've had the plant maybe 6 months. Its in my 20g under a Coralife twin-T5 fixture (36w total). I accidentally left the lights on overnight & all the plants got a thin sheet of algae on them. All recovered except the big one. It appears that one of my Loaches thought he looked tasty all covered in algae like that & turned the leaves into swiss cheese. The algae is all gone, but some of the leaves are already clear & dead, so I'm trying to nurse the rest of the leaves back as much as possible.
I was holding off on the next WC so I didn't mess up the o2/co2 levels & give the algae a chance to grow back. I dont run a co2 system & I read that algae react quicker than the plants... Is that true?
