hello all! i've been reading this forum for a few months now, but this is
my first post. i have a penguin 350 on a 40 gallon tall freshwater tank and
it's been giving off a large number of microbubbles. really tiny bubbles that
give the appearance that the tank is full of debris. i have live plants, but not what
would be considered heavily planted. i have 9 kribs, 1 syn. petracola,
1 bristlenose pleco and a snowball pleco. i also use a cheapo co2
infuser (tablets), but not on a regular basis.
i've eliminated the following: crack or hole in j-tube that may be letting in air (took it off and checked it...it is air-tight),
water level (i get the same bubbles w high and low levels), filter media (i've changed the filters and ran them in different slots, to no avail).
even if no one has a solution, i'd like to know that i'm not the only person with this issue.
from the research i've done, the only people i've found with a similar problem have saltwater tanks.
