Is this fuzz algae or a short form of hair algae?

This type of algae has covered all the plants in my tank from rotala green to dwarf hair grass. What is it and how can I get rid of it?

Tank details:
Size: 60P
Ferts: EI
Light: ADA Aquasky but just changed to Twinstar LED, 7 hours a day
Water change: 50%

Wow, that's quit a crop you've got there! I don't know what kind of algae it is, but I had an outbreak of the same algae on my rotala as well...not as lush as yours...but a pain nonetheless.

First questions are...are you using CO2 and, are you dosing iron? I ask because without CO2 in a planted tank using an EI fert regime you are very likely putting too much nutrient into the water for the plants to effectively utilize. In short, you're over feeding so the algae outbreak is on steroids. I ask about the additional iron because after my own problems I had read on numerous sites that too much iron specifically, can contribute to the problem.

What did I do to get rid of it?

First, I ensure a good balance between Co2 and light and keep my PH right around 6.8 to 7.0. I use NILOC's THRIVE liquid fertilizer which provides necessary micro ferts, but after using it at the recommended dose immediately had algae problems. I cut it back by about a 50% dose, plants are thriving and algae an almost non-existent issue. I mention it because of your EI regime, and without CO2 its probably too much. For the algae you have (and I as well, but less) I physically cleaned of as much as possible by rubbing the rotala leaves between my fingers and quickly vacuuming the loose algae out of the tank. While the filter is off, I then sprayed hydrogen peroxide (H2O2) on each affected plant underwater . BE CAREFUL, H2O2 will seriously injure any livestock you have if overdone. I killed my first Betta because I had sprayed the plants when they were exposed out of water during a water change and it was far too much in too little water. It burns the gills, there is no recovery. I won't do that again! Finally, I dose SEACHEM's EXCEL at the recommended dose and do a 50% water change every week.

Results were not immediate and I repeated this procedure over several weeks, but each week the algae was a little less than the previous week and after about a month or so I was free and clear. I have maintained the EXCEL treatment, and each week cut off any leaves that have significant algae on them. I also have AMANO shrimp, a couple of cories and several Nerite snails in the tank to help out. You'll hear from purists that using EXCEL is cheating, you have to id the core problem to really resolve it. Their right, of course, but I'm too impatient and prefer to cheat with EXCEL. I'll eventually wean myself off the EXCEL and see if I can control it naturally...but not yet.

Maybe others have some ideas, but this has worked for me. But again, you've got a pretty heavy crop there, it will likely take longer to get rid of than mine.

You would make a few true SAE's very happy- they will eat it and get fat. Temporary solution I know, but it might help you get it under control.

10 gal planted- male plakat betta, horned nerite snail, malaysian trumpet snails
38 gal planted- cherry barbs, kuhli loaches, serpae tetra, amano shrimps, oto catfish, nerites, mts
20H "Window Tank"- pair of swordtails, some mts

Looks like green hair algae. SAE's would definitely help. What type of livestock is in the tank? I agree with what Mr. Bean is saying and you may want to add some algae eating livestock to the tank just to give you a little cushion for the future and speed the cleanup.

This looks fantastic. Have you thought about getting a chorious Doctor? Didn't think mine was working but after 3 days all algae has gone. As previously I was using hydrogen peroxide.

Thanks for the advice. I am currently running pressurized CO2, I upped it a bit but it had no effect on the algae. I overdosed Excel 3x the recommended dosage but it has no effect on this type of algae. I currently have 4 otos in the tank but they don't seem to be doing anything. I've killed all my new Amanos from the Excel overdose (doh!)

I'm surprised with CO2 you still have that amount of algae. On the Excel, it takes some time, I hope I didn't infer that it was a one shot deal. It was several weeks before I saw a reduction in algae using the Excel, but it DOES work.

Sorry to hear about the Amano loss.

Algae already cover the plant. So I think this may be the steps.

1. Kill algae either by blackout or other methods.

2. Plants covered in algae mean plants not doing well. Identified the problem and rejuvenate the plants.
