Lately I've been having trouble with this in my 32g tank. I get rid of bba first, and now this stuff starts. It's very, very fine light green threads. They are about 1/16" long and grow on my front glass which doesn't bother me, but it also grows on my hygrophila leaves that are closest to the light, which does bother me. Nothing ever used to grow on that plant even when algae was on other things, so it's very annoying to me.
Here are tank specs:
32g tank
Aquaclear 50 HOB with biomedia, course sponge, and finer sponge
Internal Aquael sponge filter doubling as a co2 diffuser (rated for 50g tank)
~60 watts of T8 lighting (40 watts overdriven 2x), poor reflectors, 9 hours/day
1/2" sand substrate covered with about 1.5" of course gravel
30% water changes weekly with gravel vac (I'm changing over to spring water, don't want to shock the fish too much with the much higher pH and KH)
About 2x/week dosing 1/4 tsp KNO3, 1/16 tsp KH2PO4, 1/8 tsp K2SO4, 1/8 tsp Plantex CSM+B; up until the change to spring water I was also dosing 1 tsp each of calcium chloride and epsom salts per water change
Nitrates always test non-zero (~5-10 or thereabouts)
diy CO2 measured with a drop checker around 20 - 25ppm (light green - as soon as it gets to green I change a bottle)
Temp around 80
medium sized chunk of driftwood
Plants - hygrophila which grows very fast, pruning every week
a few crypts
a bunch of anubias
loads of java fern
some ludwigia
I would say it's moderately planted, with slow growers dominating the scene
Fish - 2 juvenile angels, 7 female bettas, 2 neons, three oto's pretty light stocking I think
I've had this hair algae for a few months and it didn't bother me too much because the bba was bothering me more.
But now that I've got my co2 fixed, the bba is basically gone except for what I need to finish pruning out, but this stuff is still going nuts. I have to scrape my glass about 2x/weekly to keep it off. No other algae to speak of. Maybe it's just my mind, but it seems like I get more of this stuff every time I do a pruning/fertilizing.
