Help please, plants browning/algae on sand

Hi, so I’ve recently set up my new 240L tank, it has pressurised co2 with inline diffuser at around 1bps, it has a 14.5w led light, and a 59w fluval plant 3.0 light. It is soil substrate with root tabs and doses with liquid ferts and iron supplement as per instructions

tank is empty in terms of fish stock and there’s no other plants in here apart from a bit of moss and a java fern.

the seeds grew fine and the carpet is filling out nicely, but the past few days I’ve noticed the plants browning more and more, as well as algae forming on the sand.

edit: I’m also getting done white fur on my driftwood in areas

can anyone help? I’m worried I’m going to lose the whole carpet

 

I think it is just diatoms growing on the carpet plant. See if you can gently rub it off with your fingers. Diatoms are harmless, just a little annoying but common in newer tanks. Pretty sure that's what is growing on the sand too. As for the wood, if it's also a new piece then that's normal too as they get a little fuzzy and slimy for a couple weeks. I like to toss my new wood in a tank with lots of snails and plecos, they do a great job of cleaning it up before I put it in another tank.

You seem to be going for the pristine aquascape look, something I know little about. For the average tank setup a bit of algae is normal and indicates an established tank. It doesn't really hurt anything unless it gets out of hand at which point you'll want to look into increasing water changes and/or decreasing the light period. Don't take my word for it though as I'm no aquascape high tech master.

 

Tank looks great! Can I get a full pic? I agree with everything that Demeter said.

Thank you, attached.
I'm still waiting on a delivery of plants so it looks bare, but should fill out, and I’m still waiting to put the rocks in but I want to see the plants first.

as for the fungus on the wood, the wood came out of my 600L which had been running for a while without this issue, and there is algae on the carpet, but it’s 50/50, some are also browning and one or two plantlets are dying and have semI transparent leaves

 

Also it may be worth noting that nitrates are quite high, around 50-60ppm, from the soil... I know this can cause issues but not sure if it’s quite related to this

Cant wait to see the finnished product!

 

There’s been a massive acceleration overnight of the brown algae, I think action needs to be taken. What do you guys suggest?

 

Algae eaters. What kind of theme are you going for? That will help us decide what king of algae eater we'd suggest for you.

 

It’s just diatoms. Every new tank gets them. They will go away on there own. The driftwood is normal too. It’s just fungus. It’ll also go away.

also plants die back or melt when introduced to a new tank. But I think yours just have diatoms on them. You can rub them off with your finger.

 

I have some large plecos to be introduced, breeding pair of bristlenoses, candy stripe, and a gold nugget. (Too many for this tank I know but haven’t got another tank for them just yet)

but I think they might destroy my carpet

 

Also, do you think that my lighting schedule is ok so far if this is the process the tank is going through?

Sounds like you're getting plenty of good responses so far but I'll add my two cents anyway:
The wood is normal it's harmless tank fungus. It'll die off when its done its job. The massive driftwood in my profile picture was covered in it during the cycle and I left it alone now its home to a lot of moss.
As has been already suggested rubbing the leaves will remove the algae from your plants. This actually works quite well. I did this while cycling and my plants are still alive and well.
In my experience during cycle is algaes one real time to 'shine'. My tank had lots of algae worrying me for the safety of my plants while cycling... then I found hitchhiker snails that ate most of it and the rest was somewhat surprisingly finished off by my guppies. Hadn't expected them to eat algae.
