I have anubias with my discus. I agree with the above.
Quick fix peroxide. You can take the plants out and soak
in a tub for 15 minutes. Use a toothbrush to remove algae.
I changed my photoperiod to 6 hrs. I tried ferts but all I use
now is excel. co2 is fine. One other thing I did was I made
a screen to put over tank. It lessened the amount of light
going in. That had an surprising effect on the algae growth.
Hi,
Agree with most of the comments :
- Not enough fast growing plants,
- Don't need so frequent fertilizer adds,
May could you also change change the bulb lights. Form experiences tubes need to be replaced each 6-8 month
The use of peroxyde is the best alternative but you need to evacuate the most of ferts excess before by regular waterchanges.
Don't exceed 30% of WC you can proceed during 3-4 consecutiv days.
Massive waterchanges inhibit the effect off CO2 injection and make the parameters variying too much
Kind regards
At least my fish look happier than my plants.
I think they should have spawned by now Jorg if there were mixed sex batch .
Almost 2 years with no pairing and spawning activity sounds like all males/ females batch to me .
My current 9 discus batch is about 15 months of age and still no pairing and I doubt about any future chances of pairing at this age .

But it seems highly unlikely that a random batch of 10 Stendker fish from different tanks would all be of the same sex...!!
And they were randomly selected by staff at Stendker, not me choosing the largest fish or something like that. They were 4-5cm.
Are there really no other factors that can keep them from spawning or forming pairs?
Your advice was really helpful. After a couple of days with large water changes and no ferts the growth of algae is reduced by at least 90%!
Spraying H2O2 has been interesting. All plants except Java Fern Nana took it well. That one looks burnt, almost black.
I sprayed on different surfaces in the tank and was happt to discover that they are now completely clean. Things that are hard to clean, like air hoses snd filter outlets now look brand new. I will definately be spraying more in the future instead of trying to wipe these things that are hard to reach!
I'm glad it worked Jorg.
How did you spray h2o2 on plants ? On dry while draining the tank or with pump straight in the water ?
Did you use 3% Sol. Or your original 17.5% Sol.?
What treatment duration did you use ?
I know that soft leaved plants can burn and melt , but I didn't expected from Java ferns to do so .
Algae on the other hand don't die instantly IME , but just get burned , change their colour and they slowly die off in the next 4-5 days.
Anyways I'm glad that your beautiful tank is spotless again .
Please indulge us again with some more photos from your discus and tank when you can .

Filip, I diluted to approximately 3-5% in a spray bottle.
Regular Java Fern, Windelöv and Narrow took the treatment well. I guess the Nana is more sensitiv.
I sprayed on all plants above the surface during large water change, so they were treated 5-15 min. The Nana is high up, so that one probably 15 min.
You know the coating that easily builds up around the tank just above surface level and on air hoses to sponge filters? I sprayed everywhere and noticed after some days that all the coating is completely gone. Don't know what algae it is but for sure a nice surprise!
Thank you Filip for your advice and encouragement!
Now some of my Anubias Petite have melted, so I've learned that 15min is too long. Will spray right before the plants go under the surface during filling in the future.
Remove the phosphates and you remove the algae, simple, no need for chemicals.
