What all do you have in there. I saw Anacharis (something I've never had luck with, it just melts), maybe Bacopa, some swords, and Java Fern.
IIRC, I have 2 Amazon Swords, Anubias (Nana and Petite), Crested Java Fern, Cryptocoryne (Wendtii and Spiralis), and Water Wisteria. In the video, you will notice 2 purple plants, (left-rear), 2 large plants, (center and right-rear), and a burgundy plant, (left-front) - those are plastic. I have since removed all of my fake plants.
