If you have hardy fish like SAE/octos/common goldfish, you can perform
greater % water changes, just make sure to get that water back to acid
levels with Co2 injection or however you keep your ph at 6.5. Im speaking
out of experience, but im pretty sure you can do more water changes, water
changes simply get the green out right away so the real plants have a
better light absorption rate (green water reduces the amount of light in
the water). Its probably good enough to get the water to a light green
state, then just make sure your plants are doing their job.
