Why is it that after a water change the plants immediately start pearling like crazy? (mine anyway).
Normally my plants start pearling 6-8 hours after the lights have been on. But I could change the water at any time in the morning and the plants immediately start pearling to the point that they get covered by bubbles after minutes. This never happens again until the next water change.
At first I thought this would be because the tap water could be saturated with O2 which is why I see the pearling right away. The problem is, I can leave the water in a barrel for 24 hours and get almost the same results. Also, I never see this level of pearling again throughout the week, even after 10 hours of lights.
If it is not the above, then is it nutrients in the tap water? Can't be the normal N, PO4 or standard traces because they are available in abundance in my tanks. Only other thing could be Ca & Mg, but then again I can add them at any time and do not get the same level of pearling.
Can anyone enlighten me?
