Do you use any root fertilizers like jobes etc. If so a piece might have
gotten to the surface of the gravel and gotten into the water column.Also
how are your phosphate levels from your tap water.If you have high levels
with high light you will have green water.Its not
harmful just not good to look at.On way to clear it up this worked for me
was to use Kent Pro clear I used it twice and with water changes the water
cleared on its own in about week and a half.This stuff works right away
within a day water is crystal clear.Your going to need to change all filter
media after using it.I dont recommend using it long term as I am not sure of
the long term effect it could have on fish I have read it could possible
harm gill function if used to often.Just follow the directions on the
bottle.I was amazed how well this product worked.
I also added a really strong water column feeding plant a water sprite that
plant grows like crazy I need to keep cutting it back.Give this a try you
should have great success it worked for me.And also watch out how much food
your feeding. Also listen to the last post make sure you have proper Coo
levels this is essential to keeping your plants growing properly and keeping
algae to a minimum.I wish you good luck it really is not fun getting green
water I hated it since my tank is in my living room. I think what happened
to me is my clown loach dug up a piece of jobes.Also regular fertilizers
such as flourish or TMG will not cause green water problem. Excess
phosphates and high nitrates will however with high light levels. I know
people that grow green water on purpose to raise daphnia.You can also read
more about green water at the Krib which is a great resource tool to use in
Aquarium hobby.

The kH is about 2 degrees while the pH is around 6.8 (gotta check.. lots
my
CO2 kit color chart hehe)

Given your light levels, I would really try to increase your CO2. With a
KH of
2, I would aim for a pH of 6.4. Assuming you aren't using phosphate
buffers,
that is.

See this page for recommended CO2 levels:
