Help. Algae taking over my tank!

Hi all , over the past few months this dark red/black hair algae has been growing everywhere in my tank- plants,decorations,glass and filter. I have been physically removing it from decorations and the glass and have tried to cut away parts of the plant with this algae on it. However after every clean it comes back and in a week is all over the tank again .I have attached some images of it. Any help would be appreciated.Thanks.

 

Looks like bba. How big is the tank and filter? How often do you change the water? How much nitrate in the water? How much light? Hours on and what type of light.
This algae is very hard to get rid of. On all hard scape you can do a peroxide dip. Remove it from tank and soak in peroxide for 10 min let sit of 10min than rinse in sink and return to tank. It will turn red and later pink and go away. For plants you can try a 3 min dip. But many plants will melt after this.
Things that do kill it over time are api co2 booster and seachem excell. These must be used daily. Next if your tank is big enough a Siamese algae eater will eat it.

 

Hi thanks for the reply. Its a 100 litre tank with a fluval u2 filter. I change the water weekly with about a 25-35 percent water change. i have 2 lights a aquael retrofit sunny,plant LED.These are usually on for aroudn 10-12 hours a day.i did a test this morning and NO3 and NO2 were in safe.

 

Start reducing to 8 hrs., regardless. Dim the lights for any additional hrs. for personal pleasure....when the algae problem is solved of course (referring to the pleasure part).

A picture of the whole setup is more helpful than images of algae; most of us know what that looks like .

Water changes in itself doesn't suggest that much; no idea of the water parameters that are going out and subsequently going in your tank.

 

Agree. Reduce the lights. I would go to 6 hours with dimmining on either side.

Are you sure you are testing for NO2 (nitrogen dioxide)?

Not tryna be rude but no2- in our test kits is nitrite btw which is different

Yes i use the tetra test that test for NO3 NO2 GH KH pH and Cl2

 

Your still going to have to either dip it or just remove it by hand. Than reduce lighting. You can put the lights on a timer with an on for4hrs off for 4hrs than back on for 4hrs. The off time in the middle keeps the algae from growing. Good luck.
