Well nearly a week on from planting and all is fine apart from the Blyxa which has melted away. Crypts in the tank appear fine and other plants appear to show signs of growth. Will Blyxa recover? There are two areas of it in the tank on either side. Bizarrely it's the group nearest the diffuser that have melted the most. Flow around the tank seems pretty good as bubbles of CO2 seem to be reaching everywhere.
