Browning moss/plants questions

So currently my show tank has fissiden, dwarf hair grass, peacock moss, rotalia colorata and the green version

The problem is my tank has green spotted algae, some puffy black algae (might be Cyanobacteria) and green hair algae (I'm pretty sure it's green cause it looks white but when I clump it it's a dark green)

Before I use to just use flourish and flourish excel and seachems rooting tabs but the algae spread like the plague
So I decided to stop the whole lot of it thinking it's probably the excess nutrients

2 weeks ago I decided to get a co2 unit with solenoid, regulator and the whole Sha-bang
But still after 2 weeks in, the hair algae, spotted algae are still growing prominently and my grass, fissiden and peacock moss are browning and I'm quite confused what's wrong.
I can see pressed against the glass are simple runners of hair grass, they are a beautiful green under the gravel but when it grows to the top it Browns
I'm quite confused
Why hasn't the algae stopped and why are my plants browning....

Any help would be appreciated

 

What kind of lighting do you have?

Are you adding any ferts at this time? Root tabs? What kind of substrate do you have?

 

Along with answering TexasDomer's questions, how long has your tank been up and running? Also how long do you run the lights for?

 

Thanks for the replies!
Umm at the moment I'm not putting in ferts or rooting tabs for about a month now, because I'm afraid that the nutrients will make the algae go mad and mass produce .
Unfortunately when I started the tank I want planning on growing plants so I have aquarium gravel that's coloured black. It's not diamond blasting sand it's just gravel. But it's pretty fine it's like the size of an uncooked Cous cous grain if that helps.

The tank has been up for about a year and a half now and it's fully cycled. My lights are on for about 11 hours along with my co2

 

11 hours is a really long time for lights to be on. I'm guessing since you are doing co2 you have pretty high tech lights too. Algae problems can occur due to imbalance of light, co2, and ferts given. It may be growing so well because your lights are on for so long.

Gravel should be fine for plants, they don't need sand. You may need to do some root tabs/ferts for the plants.

 

I have zero knowledge of planted tanks, but could the algae be outcompeting the plants for nutrients?

Yup that's true too.

 

I'm also curious as to the types of lights...Leds shouldn't be much of a problem but I know from the saltwater world, when running bulbs like T5s or whatever, once they started to weaken they would put off a spectrum that was less ideal for coral growth and more ideal for algae growth...An algae bloom in a saltwater tank sometimes meant it was time to change your bulbs.

 

Currently I'm using the aqua one plant glo led lights

Using ferts won't cause algae outbreaks. It's often too much light or too low of CO2 that does it. If you're using CO2, you need to use ferts. Use root tabs in the substrate for root feeders and use liquid ferts for water column feeders.

Agreed, shoot for ~8 hours. You can break it in half too, so it's on when you're home (4 hours on, 4 hours off, 4 hours on).

See above. Do you know what the PAR ratings are for that light?

 

I see I'll go grab some flourish, flourish iron and rooting tabs tomorrow!
Could that be why my plants are turning brown only when they hit the surface of light?

Ok I'll set my timer on a 4 hour cycle hopefully that will solve the issue!

The par rating however I'm not quite sure about, I don't think it specified on the box of the light and I tried a rough Google search with no avail

But I'll give it a week from tomorrow and report back here on how the plants are going! Thanks!

 

So I've tried out all those ideas and the green spot algae is starting to slow in growth... I think, I don't see any forming on my screen at the moment which it usually should
But I think he areas with it are far from dying lol

The hair algae however is still running wild I pull and pull and pull and it still grows back
Are there any more ideas?
