well since i just put them in, there has been a lot of debris in my tank, little plant fragments and such. they are kinda clogging my filter intake and i need to clear that out.
i haven't really noticed any change in water clarity, it looks as clear as it always does. i made sure i rinsed the plants off well before i put them in.
i don't have an O2 test kit so idk what they're doing to the O2 levles, but probably increasing them. when i first had the plants in there they were covered in tiny bubbles, that have since vanished.
