My 4DKH solution remains green to yellow meaning I believe it is within 30ppm.. But fishes sometime come in contact with the CO2 bubbles coming out of diffuser when they swim through these bubbles. . Want to understand if this (fish coming in contact through CO2 bubbles) is harmful to fishes ?

I have not researched this specifically but I would assume it is fine because many people have CO2 microbubbles in their tanks. I actually recall a post in particular where the fish enjoyed swimming through the bubbles from the guys in tank glass diffuser. I have never heard of it causing a problem.
 
You gotta give people more than three and a half hours before bumping. Especially at 2am, my time. On the east coast, that's only like 4 am, with a 7:30 ish bump. On a Sunday morning? People who aren't partying and still up or have to get up early for work are still in bed.

That said, unless your CO2 is causing a change in pH that enables other issues to surface, no, it shouldn't be a problem.
 
+1 on all said...

I use an inline diffuser with my canister and it comes out through a spray bar but my rainbows which swim right in the current in front of the spraybar do just fine...you shouldn't have any issues!

Thanks myswtsins, authmal, TheFishBoss97 for all your inputs. .

That is like blowing CO2 at you, it is not harmful unless you have too much in your water.
