Green Hair Algae issue

Featured Replies

so i cant stop this from growing, ive turned the light down to like 1 hour a day and still growing, how the hell do you get rid of it

You've been having trouble with algae for awhile hey? Can't work out why though.

 

What's the set up you have? Like filter, lighting, substrate, do you use any ferts? What are the water parameters? Might pay to test everything and post the results on here.

 

Also, take a photo and post it up here so we can check it out and have a closer look.

You're going to have to resort to taking plants or ornaments infected with the algae for external treatment.

filter is a canister filter, lighting was one i got from banggood people recommended to me, forgot the name, stopped using ferts, all plants dying now... oh well, parameters are all fine

 

i just cleaned it out with my hand, so not much in there but in 3 days it will be back

nope no co2

 

i use to use Flourish Excel but, i stopped when it the algae started taking control to much

Plants look real healthy, it's just that part that is an eye sore, I guess keep removing it, or perhaps spray some H2O2 on the areas.

they are not healthy anymore, they all going to die apart from the moss, and the java...

Just get the EasyLife AlgExit from one of our sponsors. I had somelike in your photo gracefully waving in the current in my wall tank. It all disappeared with the treatment. It is great.

yup doesnt work, it didnt kill any algae. i also tried the 10 times the dosage in a bucket, it also didnt work... my shrimp also didnt like it, lost all my yellows from it

That's super weird, did you do the weekly dosage once a week for 4 weeks like it says on the label? I followed the instructions in my 700L tank and it worked a treat. Did not effect any of my Riffle Shrimp in that tank. It worked so well that now I use it in my fishroom. Since then I used it in tanks with Snowballs, Red, Black, BlueBlack, Carbon and Red Rili tanks (all separate tanks) and as far as I can tell haven't lost a single shrimp.

 

In some of the above tanks I even used the AlgExit together with BlueExit; shrimp are fine! I am confused!

A note: It doesn't kill the algae instantly, algae just disappears over the weeks.

Like Serkan, my experience with Algexit has been great as well.
Don't know why it's not working for you.

Edit- just a thought, check your levels of iron and phosphate.
It could be excessive. So the normal dosage of Algexit is no doing anything.
If you don't have a kit, see if your LFS can test it for you (maybe for a small fee).

 

High levels of iron can cause algae growth, and will contribute to high GH or TDS readings.

GH readings are also affected by strontium, aluminum, barium, iron, manganese, and zinc. These also cause hardness in water, but aren't usually in large enough quantities to impact the GH reading. 

 

Are you using rainwater stored in old aluminium, iron or zinc barrels or tanks?

This looks like spirogyra and is one of the toughest algae to get rid off.

-Remove as much as you can manually.

-As for all fillamentous algae increasing flow should help.

- introduce more plants to suck up the available minerals or run activated carbon to deprive them of food and they will eventually die, plants can sustain longer so they will hang up for longer period.

- for heavy infestations You can use blackout method for 5 days by covering the tank using blanket with lights off.

i did it for um 8 weeks i think, and i also took plants out in a bucket for 3 days with 10 times, then back in tank, then 2 days later back in a bucket with 10 times and the algae didnt die with it... maybe i have a bad lot

they are new plastic tanks, TDS is 30 in them
