I don't know that fish mulm is the cause of green water. It depends on the
nutrients available in the water, _supposedly_, right?
Side by side, I have 2 10-gallon tanks: a flourite tank set up next to a sand
over peat & kitty litter on the bottom. This 2nd tank has not ceased to be
problem for me, despite redoing a few times, adding more sand on top,
clean-outs etc. One thing I can count on, the water will eventually turn
green, and I don't know why. Even when there is no fish in there. Even when I
block off the back of the tank from daylight. Even after I started pumping in
co2.
Next to this I have a flourite tank. It is open to daylight and has maybe 40
watts lighting over it, no co2. Just last week I I pulled out heavy growth of
cabomba, some egeria, and a lovely type of mat algae that comes easily off
the plants. IMO, this is a desirable algae to grow, and I'm thinking of
introducing it into my other aquariums. Anyway, the plants had to come out,
because it was time to thin out the ever-growing fish population. There must
have been about 200 fish in there of varying sizes, guppies and platys, and 1
betta. There was so much mulm collected on the flourite that it coated it in
a layer. I feed the tank at least 2x per day, since there is always fry and
growing fish.
In any case, this tank has NEVER had green water. I was just thinking of
posting a question to the list myself, as I'm wondering whether a tank with
flourite ever had a green water problem (guess they do). I'm thinking of
taking that eyesore tank, and dumping the substrate and replacing with
flourite, but I really like the look of the sand.
I can't help you out on your question as to how to thoroughly clean your
flourite substrate without uprooting your plants, but I can offer that I
don't think it's necessarily the problem. Want some of my algae?
