yea i noticed that when i prune my wisterias, the open stems would gas out after water changes.
thats what i figured all of the bubbling were since i prune them alot.
Right now i dont have any issues with the plants and im doing VERY well on algae control atm.
After a few weeks of trial and error im starting to understand how my tank eats up the nutrients and what not to dose and what i should dose more often.
As for the dropper checker ill just keep it clean whenever i see white scum
I just thought it was gross :P
