hair algae

I have a 10g planted tank with one oto and 6 neon.

I change water every week. But I am using 3 of this light for 6 hours

Is it possible that causing hair algae ? thanks

possible but not likely since that is considered low to barely medium light.

I guess I will need to do WC every 3 days and add co2...see how it goes....

Are you overfeeding? Hair algae seems to love the tanks of overfeeders... I'm one of those said people. ;-)

baysidefish 09-26-2012 03:22 PM

I dont think so, I feed them every 2 days...thanks

baysidefish 09-26-2012 03:22 PM

one thing though, I never siphon the tank...not sure if it matters..

btw, the water does not seem to be the problem, because I have a 8G shrimp tank, they have the same setup. The only difference is the light.

Shrimp tank I have this

i have a variation of that same light over a refugium/breeder. its considered low light... Algae is normally triggered by excess light and nutrients.

Your bioload and light will not likely give algae enough excess to start up unless its by a window recieving some sun.

it is not by the window. but the room has natural light into the room

I added about 3 otos, small ones after last post and did wc 50% weekly. Algae grows longer and longer. Any thoughts on this? A shrimp tank next to it has no issues at all. Thx

I'm still fighting off a hair algae invasion in a 10g tank. I cut down the light intensity and photoperiod (2 13w CFLs) and have increased fertilizer 25%. Making small moves here I hope.

You might try vacuuming weekly. My hair algae is at the top surface of plants. That makes me think that the light is too high, but I could easily be wrong.

If you haven't already heard this, you can use a toothbrush to remove hair algae by picking it up by twirling the brush.

Just my opinion: hair algae has very little to do with light and a lot to do with the strength of the current: too little or too much and here it comes (same with BBA).

I would decrease the flow slightly in the smaller tank and keep on removing the algae. If it's still in the tank ~2 weeks later, decrease slightly again. Adding Excel x2-x3 the recommended dosage will help.

Hopefully you will win sooner then later.

thanks, can I use as excel? thanks

OVT 10-12-2012 12:33 PM

You could. Pretty much the same as Excel, I think.

baysidefish 10-12-2012 12:35 PM

ok. thanks
