They are already starting to stick to the hygro int he back.
I dialed the outflow down a bit and now its shooting out even smaller bubbles. I think less flow is okay since the tank is full of small tetras and danios and i can still see a bit of movement on every plant.. some alot some slight.. but its there!
I also direct the outflow a little more down so its more across the tank then towards the surface..
co2. doesn't really stick to plants.. it dissolves very rapidly. if i turn my lights off, bubbles dont really build up under the leaves, a few do, but they are small. lights on and they become a lot larger. more than likely your plants are pearling due to photosynthesis
Once i turned down the flow a little more there was almost zero bubbles coming out of the outlet... So i think It was either air in there from the canister burping it self or to much flow and not enough dissolve time.. but with it turning it down a tick or two seemed to have done the trick!
So i turned my FX down by about 30% to lower the flow enough where it didn't push out bubbles.... would it be worth shoving in a few pot scrubbies to "smash up" the water/co2 bubbles as it exits to allow me to turn the flow back up a bit?
The only issue would eb if i ever had to clean it... WHich i'm not sure if/how often you would ever have to..but something to consider.
