algae in water?

I have a 20 gallon tank, two 20 gallon tetra filters hanging off the back,
the ph is 7.0, 10 fish and the water constantly turns cloudy to green. I
change 25% of water per week, its not in direct sun light, the temp runs
around 70 degrees. Gravel on the bottom and three plastic plants, thats
it.

Would appreciate any help you can provide!

I have this problem in my goldfish tank- I've always attributed it to the
fact that I feed them generously and have no live plants in there to soak up
the nitrates.
I do manage to keep it under control by running a diatom filter for a few
hours every couple of weeks.

My planted tank gets way more light and has a much higher fish load, but is
crammed with live plants so no algae manages to get going. Maybe you could
add a few hardy live plants?

Having fought several alge problems, I have arrived at my solutions
with trial and error.

Water changes are one of my pet preventative steps.

It is now my opinion that not only does algae grow from the amount of
light it recieves, but how many hours it recieves that light. I now
have my tanks on a timing system to make sure I do not over light in
intensisty and time. I also programmed the system to turn off the
lights for two hours mid day. The tanks are still getting 13 hours of
lighting. I would prefer less, but don't like to not see my tanks.

Food, too much that is, can be a problem.

In addition to prevention, I added different fish to control algae:
Plecos, Siamese Algae Eaters, Black Mollies, and snails.
Unfortunately, I added Clown Loaches to keep back the small snails,
but they ate the larger snails as well. So no snails for me, my herd
of Clowns keep them out of sight.

There is really no need to have your lights on for 13 hours a day unless you
have a low light PLANT setup. Leave your lights off during the day if its a
fish only tank, turn them on in the evening when you want to look at them,
why make life difficult for yourself??
