Algae of what kind?


Hey, so i've recently gotten an outbreak of some kind of algae and i need to know whats causing it so i can try and rectify and rid the algae from the tank...it's gotten out of control and just looks gross now.

any help or insight on whats causing the outbreak would be much appreciated.


10 Gallon planted tank:

DIY CO2/ 1ML Liquid co2 daily
35 watts of lighting for 10 hours a day.
I dose 1ML of Flourish comprehensive once a week after a 30% water change.

GH 180
KH 80
PH 7.0
NO2 0
NO3 0

It's hard to tell from the images but most likely a hair algae, Rhizoclonium or even diatoms. The lighting seems pretty high for it to be diatoms but not impossible. How long has it been setup? New tanks generally have problems with this at first then disappears after 2 months or so.

Generally you need to dose more nutrients. NO3 of 0 is not a good thing in a planted tank. Low nutrients, high light and DIY CO2 is "the perfect storm" for algae problems.

green hair algae...i have those in my tank

been dealing with getting it clean for weeks now.. it's usually on my moss and gravel.

been dosing excel and seem to work and also manually remove it by siphon works too

35 watts on a 10g is too much light... i use to have 20 watt on my 10g ..got lots of algae..

Manually remove with a siphon? It's really difficult to manually remove it. How do you manage to achieve that? Maybe I'm missing something...

i suck it up using my special homemand mini gravel siphon...(seach youtube)

hover over the algae and suck it up...it you suck up gravel..pinch the airline tightly and the gravel fall back into the tank...

Removing the algae will only be temporary. Until you correct the existing problem(s) it will only come back. I think your lighting is too high. Check out the stickies in the lighting section and decrease to medium par at best. Your current dosing seems inadequate for good growth which will in turn cause algae. I know it seems counter intuitive to add nutrients when algae exists but it works.


This is what I would do.
  • Remove as much algae as you can.
  • Clean the filters and any loose debris from the tank.
  • Turn the lights off for 3-4 days. Block ambient light if present.
  • Change 30% of the water every 2 days for a week.
  • Dose Excel if you have it at twice the recommended dose for that week.
  • Decrease your lighting to a total of maybe 20watts maximum.
  • Increase nutrient dosing until you maintain nitrates about 5-10ppm
  • Consider ditching the DIY CO2. From my experience it's more trouble than it's worth. Replace it with Excel or equivalent.

You should not have zero nitrAtes in a planed tank. Nitrates are one of the important Macro nutrients for plants. You have a nutrient imbalance.

With that much light you should be dosing Flourish 2-3x a week as well as Flourish Nitrogen and Flourish Potassium.

I would adjust photo period to 4 hours a day, remove as much algae as possible and double dose with Excel for a week. Increase fertilizers.

So you believe that adjusting my fertilizer dosing routine will solve this problem over time?

Yes, along with light adjustments and CO2.

Down to 20watts?

Default thats tha ticket!

I have been reading this thread and I do believe my extreme lighting, long light period and nutrient poor water is the cause of my EXTREME case of the same "algea"

I can't really tell from the picture but it looks a little like diatom and hair algae.

Are you dose with sachem Complete. It so its not really Complete the number are so low you pretty much need to double the dose ,but then you might be doseing one of the elements too much.

Do you have a clearing crew such as Otto's or Amano shrimp you could do 3 of each in a tank you size. The shrimp really do a excellent job and the Otto's get the rest.

Is your light on a timer. If is shorten the time it is on. I run my light 1hour in the morning from 8 till 9 then it goes off and I go to work. Then it comes on again at 12 then of at 8pm.

If it is daitom try use some Phos-Zord in the filter to clear out and silica. I just clear up some drown hair algea by doing a water change.

Try adding some root tabs to bring up your nitrates it seem to help mine.
