my turn again...
My original planted tank's hair algae is getting steadily worse and I wonder what else I can do to knock it back. From a distance you can't see it, it's not THAT bad, but it's throughout the tank and it's noticeable.
I assume it's hair algae as it's like hair.... long green strands of what you get out of a hairbrush. It used to only live in the twisted val, so I thought it was to do with weaker older leaves as my val gets very long and floats on the top due it being a small tank. Then it spread to the other plants and now it's everywhere, even growing on the plastic breeding box floating in there.
Plants are all green and doing well.
Parameters: 28cm deep water (top to bottom), 50cm long, 27.5cm front to back.
Lights are 16w worth of 6500k and 14000k bulbs and they are on for 3 hours a day. Tank is in a well lit room but gets no direct sunlight.
Phosphates tested today at 0.25, 2nd one down from the top of the API card, and Nitrate was 5.0.
I was doing about a 4L water change weekly but over the last month I haven't done any in an attempt to create more balance.
Fertiliser is 1ml of Excel once a week, and 1ml of Flourish comp at least once a week or up to 3 times if I remember.
Once a week I get in there with a bottle brush and twist out as much as I can. Don't get very much other algae in there to speak of. A few tiny spots of black beard or brush on the old java fern leaves, a bit of green spot on the glass from time to time.
edit.... also tank gets 1/8th tsp of epsom salts a week
