green algaes died off

[danny]

i finally have a pond,a goal reached!
pond is 10'L x 4'W x 3'H.
Fishes are:
1 gator gar -1.5'
1 florida gar -11inches
1 redtailed catfish -10inches
1 adult albino oscar
3 flowerhorns(1 adult and 2 juveniles)
1 texas
3 senegal bichirs

well,everything was awesome until algaes.1st it was the brown algaes,then came the green algaes.i did not like it but i did not mind at 1st.then i realised it is a problem to feed the catfish(i always handfeed it to ensure that he gets to eat) since i cannot see where it is.so i started reading Carl's articles about 3weeks ago.i added some floating plants like water hyacinth and water spinach plus a lot of aquatic plants.i was not able to find the plants that Carl recommended as bog plants,so i had to settle for lucky bamboos that was growing in our backyard.it was perfect because their roots were already thick and clumped up.i put it next to the internal filter following the article,it was working as the agaes started to thin out bit by bit.
But last yesterday,water was all brown.the green algae died off.
Is it me or is the death of the algaes too quick or sudden?
And i should be doing water change right?

This is unusual for the algae to die off quickly, normally the algae slowly "starves" off (mostly the free floating algae).

Make sure your veggie/bog filter has some water movement through it and that there is a good rock bed beneath it (I prefer volcanic rock)


I would recommend a 25% water change, & if at all possible; suction any muck off the bottom.

As a side note; If a UV Sterilizer is present, make sure to change the UV Bulb every six months

i did the water change and siphoned the bottom as much as i can.
the bog plant are placed besides the filter,so there are water movement.i am not sure if the bed rock i used were lava rocks.i used the ones i collected from a local river.
I know the green algaes will be back.but i wanted to know is,what the water will look like when the veggie filters has starved/killed the green algaes?will it also be brown?or will it slowly clear as the death of the algaes are gradual?

[Carl]

The water should be reasonably clear with a slight yellow tint.

thanks Carl for the help!

Agree with Carl - it should be clear with a slight tint. At least that's how mine is when the algae is under control.
