Honestly the secret to algae control is snails and bugs (pods and scuds). If you have a local water source like a pond or creek or even a gutter just grab some mud from the bottom with old leaf litter and put it in your tank. This will give you the micro fauna and flora you need to balance things. The closer you can get to a natural environment the better. I made a video about natural aquariums here https://nightshift.minnix.dev/w/wpz7LehrYLcK4856Lkg6Sq
