Hi all 1st time post so please be gentle ☺️ So... I’ve had my tank for a couple years and been trying plants for around 6-8 months. Really struggling with BBA and holes in my amazon sword. I’m trying low tech with regular (weekly) water changes of 50%. Don’t dose anything in there. Done the seachem excel concentrated to a specific area for a week with no luck. Can anyone help a very novice hobbyist out?
