and greenwater can get dense enough to block light to deeper depths

learning about greenwater in my tank or what used to be greenwater & whatever it is that prevents me from getting a culture going again.

i'm tempted to remove my HOB filter, ... but not confident that that's a smart move yet.


i took a 50/50 mix of tank water with greenwater culture (stable culture, doesn't want to die in it's bucket and i ignore it)

almost a week later and it's still the same light green it started out in
in tank after adding some greenwater, aside from the first day, each day after that the water got lighter and lighter till about a week later it was crystal clear again, ... so frustrating.

but i think (i hope) i learned something, ...

it's nothing toxic in the tank that is the issue of what is killing off my greenwater
something is either eating it or it's not surving the HOB filter :/

extra frustrating.

i'm sure beaslbob will suggest "remove the HOB filter".

it's strickly only mechanical filter, nothing else, ... i've removed all other baggies and other materials except the foam blocks i've filled it with (i love those things)

but it seems (guessing) there is something about them that is killing the greenwater that i so desperatly want to survive and even thrive.


i'm at a bit of a loss unless i want to experiment, experiments are good
i can turn it off and leave it disconnected for several days (weeks maybe) to check and see if adding greenwater dies off as it has been or begins to thrive.

i'm curious about input, ideas, knowledge (as little as there is about maintaining a greenwater culture)
even knowledge/experience of others who have learned what to do and what not to do by their own trial-and-error.

if things are good i can start getting stuff i would really love to try in the tank
-a freshwater sponge (gotta get creative to see how to get it survive with flagfish (if this is problem))
-remind myself to stay away from clams
-zoo-plankton (likely daphnia, and worse probably magna species - isn't there anywhere in canada that sells smaller daphnia or preferably moina ?

one inquiry led to another inquiry led to wanting to continue this farther.

with such a light directly in the tank, there was mentioned to me concerns about this causing problems, i'm not sure what problems, but i'm curious.

i am curious also on culturing greenwater, and populations of zooplankton that would be encouraged as well in the same tank

i could expect higher densities of greenwater with such bright light (provided sufficient nutrient availability) with more greenwater food for zooplankton present i could expect higher densities of zooplankton (provided there was sufficient filtering due to increased waste from higher zooplankton concentrations) ... or as a minimum an easier time for the zooplankton to want to reproduce more due to the abundance of food for them

i'm curious about any and all feedback on this idea and related thoughts.
