Green Hair Algae Slowly Growing

I recently got a co2 system for my 40 long and along with it I got another LED light for my tank. It was one of the NiCrew LED ones from Amazon. So I have two of them (48inch) long ones, which I think would be considered high light?

I have several red plants which is why I thought I would need two light fixtures, and my plant is slowly starting to get heavily planted.

In the process of upgrading my tank, I’ve found that green hair algae and green spot algae has been slowly growing more and more day by day and my sponge filter is basically infested.

Some things I’ve tried:
- Added 5 more Amano shrimp to my 4 already
- Pump more CO2 into the tank (bordering yellow drop checker 1 hour before lights go off)
- Get more plants to combat the algae

I use NilocG Thrive and pump 4 times (1 pump per 10G it says) and do it 3 times a week. I change about 40-50% of water every Saturday.

What should I do here? I run my light 8 hours a day on the timers, which I feel like is already on the lower end and I’m not sure if I should shorten it.

Amanos will work on algae on decorations and filters, but the glass needs some more backup. A group of Otocinclus should do the trick.

 

Unfortunately the amanos (9 or 10 of them) don’t seem to be making a dent in the algae on the filter or plants. Although, they are very active I think I just have that much algae.

I already have 6 otocinclus that I never see (only at night) and the glass is full of algae. Their bellies are also very big which I assume means they’re eating well…

not sure what to do as cleanup crew seems to be full

Hmm. Yeah thats quite a problem. Well sorry thats as far as i can help you. Im not quite sure what else to do besides lower the light

 

I was battling green hair algae up till a little while ago as well - I think I had a similar light too, the NiCrew SkyLED. I kept the light at 20% 10 hrs a day and removed the algae wherever I could see it. Had to clean my filter really well as well as it was all through the filter. Keeping the filter clean with a fresh floss pad each week along with the lower light seemed to bring it right down after a few weeks. It's pretty much entirely gone now and I'm able to bring my lights up brighter and for a bit longer again.
