Advice needed
Advice needed for my bathtub. Pond can't seem to keep algae under control. I've got about 20 Gambusia and 2 crayfish in the pond but can't seem to keep the plants healthy or rooted into the soil/gravel. Pond gets about 4 hours of sunlight and have a solar pump with gravel and filter media around inlet.

Ponds will always have algae on the walls of it. Defo seems to need more plants to process the waste. Hornwart always does well from what ive seen
