Green algae
Hi all,
I've been on the list for a while, and I am now faced with a bit of
an algae outbreak. The real problem here is taht I can't tell what kind
I have. It is a very pretty green color (dark almost a kelly green) and
it grows in sheets that cover everything. When I say taht it grows in
sheets I mean that it is easily removed and when wiped off, it tends to
come off and stay together. My tank conditions are as follows:
Temp 87F
pH 6.2-6.4
ammonia 0
nitrite 0
nitrate 20 ppm
GH 12 degrees
KH 2 degrees (this is right after a water change, before I get as low as
zero degrees)
The tank is a 55g lit with 2 40W florecents (1 plant & aqauarium and
i cool white). I am going to change to 2 Chroma 50s but haven't gotten
out to the hardware store yet. There are currently 7 discus, 9 ottos, 2
clown loaches, 1 clown pleco and about 9 ghost shrump in the tank. As
for plants, I have about 25 corkscrew val, 4 small amazon swords and 2
crypts.
If antone can halp identify my algae or, more importantly, suggest a
way to get rid of it. I would greatly appreciate it. Also, is there
anything that I could put in the tank to slowly dissolve and keep the KH
at about 3 degrees? The water is only 4 degrees KH out of the tap.
Thanks,
