Hair Algae


So I am having hair algae problem for a long time.

Tank - 9g rimless
Filter - Aqueon 10 100gph
Light - FugeRay LED 12" 44 7000k 5 watt total (distance is right above the tank)
Time that Light is on - 8 hours

The previous light I use which I also had hair algae was a regular house fixture with 60watt equivalent 6000k CFL bulb at about 4 inch away. (I no longer use this bulbe). I also had this bulb on for 8 hours

Co2 - Pressurized PB tank with dual regulator I have it on for 24/7, I do this because I want to keep my pH down.

Air - have air bubbles running for about 8 hours only at night

Plants
-a little DHG
-Fissiden
- some micro swords
- pellia

I do not dose the plant with anything

Water Conditions
100%RO
pH 6-6.5
No2 under <0.3mg/l
NH3/NH4 0.0mg/l
TDS - Not sure but probably low because its RO and I change about 1-2gallon every week some times bi-weekly


This is a CRS/CBS tank, I know that I can use H2O2 or excel to kill the algae but I would like if I don't because I don't want the algae coming back.

I would like to know what is causing the algae to prevent the hair algae.


Here are some of the hair algae. I have already move some that was bunched up in my fissiden.

It seems like you have to much light to me.. not enough plants. How old is the tank?

Tank is 6 months old. So you think I should lower the amount of time I have light on?

Right now, I'm only having it on for 2 hours a day. Well see how that goes.

How long does it usually take for hair algae to die due to insufficient light?

Add some floating plants so they take out any excess nutrients. You can do guppy grass, frog bit, salvinia etc.

I had some frogbits, about 20+ but then they started disappearing. Why could that be?

How much surface agitation do you have? Most floaters HATE moving around.

Not too much, the only agitation is from the HOB, aquueon 10 which is the smallest one.

Maybe too much light killed them as well. Try getting some floaters again...try getting a variety to see which ones like your conditions the best.

Hair algae is such a pain! I'm dealing with it on some plants a friend gave me. I have them "quarantined" in a kiddie pool right now while i dose them with H2O2. Hygroryza (sp?) aristata seems to do really well with mild surface agitation. I also love the long, fern-like roots that hang down.

Your shrimp aren't interested in eating them? Try pulsing your lighting (4 on, 2 off, 4 on) and definitely get more plants and floaters.

CRS and Amanos took care of my hair (separate tanks).

+1 on the breaking up the photoperiod.
+1 on pretty much everything mentioned above...more plants will curtail the hair algae growth.
H2O2 is a beautiful thing for algae, just be very careful with the ammounts you use. Start sloooowwwww and low.
Search this forum for more info.

Since I started this thread I change my photo period to about 2 hours a day. So far I have not seen any changes yet.

I don't have any armanos but my CRS/CBS are not eating them. I usually feed my shrimp every other day some times I forget and go 3 days without feeding them.

Should I starve them longer to see if they would eat the Hair algae?

Your light is only on 2 hours a day? That doesn't sound right if true.
