Hello Gardeners,

Well I'm back to square one pondering why it is that when I do a 
partial water change it is like I added some kind of miracle drug 
to my tank. The photosynthesis just takes off in a spectacular 
fashion within minutes of the change.

Some of you have suggested that I'm simply seeing bubbles that were 
carried in with the new water. But I know this is photosynthesis 
taking place. It's highly unlikely that air in the new water would 
stream out of particular areas of leaves (like areas with wounds).

I thought from earlier tests that maybe the new water was 
introducing more CO2 into the tank and this was causing it. But now 
that I have a digital PH monitor, I know this is not the case. The 
PH would drop when I add the new CO2 enriched water. What it does 
is rise about .03 points for about 10 minutes and then within the 
next 15 minutes the system moves back down to where it was just 
before adding the new water. But the photosynthesis is really 
something to see!

So I'm going to throw this idea out to you people and see whether 
this can make any sense at all and explain this phenomena. Is is 
possible that there is something accumulating in my water that is 
impeding photosynthesis? Too much of some trace element for 
example? Adding new water dilutes this situation and photosynthesis 
commences at the rate it should be - given the light and CO2 

If I can't find some rational explanation for this, I'm going to 
assume that the tap water here in Royston, BC on beautiful 
Vancouver Island is some kind of fountain of youth. Maybe I should 
start bottling it and selling it to you people? ;-) I'm telling 
you, something strange is going on here.

Cheers, Rene
