Many say water lily don't draw a lot of nutrients, nitrate for them, from the water compared to other plants. As the good algae takes hold on surfaces it will use much of the nitrates for nutrients. I say keep up water changes until that begins to happen. You could also add a container with plants in or out of pond flowing water through it to pull the nitrates and phosphate. Could even be temporary.I've got two pretty large, planted water lilies. But they've only been in there a few days.
So, I'll watch the nitrates and prepare to do a partial water change if it keeps climbing? Or should they settle down too now that the nitrites are gone?
