Need help with algae

[wolt]

What type of algae is this and what should I do about it

Looks like green hair algae to me.

What do you think I should do about it I’ve been feeding less and turning lights off earlier. I’m also getting a skimmer in 3 days

+1 to gha
I'd suggest a rabbitfish if tank is 100 gallons or so. Or starry blenny.
Maybe post nitrate and phosphate levels to see if those are contributing.
The skimmer will definitely help.

I actually have a starry blenny and two fangs and a long spine urchin my tank is also only 75 so I can’t get rabbit fish

If you feed less, the blenny will look for other food and perhaps find the algae.
I got a filefish for aptasia that wouldn't do his job until other food was less available.

I have actually seen the blenny eating the algae but I don’t think it’s enough to help

I have also read that covering the red and green lenses on the light will help with the algae

I agree that the nitrate and phosphate readings would be essential information. I also second the skimmer idea if you don't already have one. They can work wonders.

And white.
There are many posts that support this, when you have a light with adjustable spectrum.
For you, that is a good plan unless there is a dial to adjust color.

Here’s nitrate I will test phosphate in the morning

Not so bad, but enough to grow algae.
Do you run a refugium?

Good ol' API kits. "It's 5ish10ish20ish" lol. I use them too though. So you have some notable nitrate, but nothing too insane. How about the skimmer? It would probably help a bit with the removal since proteins contain nitrogen. Especially combined with some brushing. How deep is the sand? I like to keep 2-3 inches in most tanks to allow for some denitrification. There are other ways to promote it, but it's a simple one.

 

[wolt]

No but I’m thinking about doing a small DIY one

 

[wolt]

My sanbed is like 3 inches

I'd suggest an algae scrubber.
Or
To export nutrients.

DIY skimmers with air stones tend to skim extra wet, or unreliably, but all skimmers need some attention from time to time and the price is right. I have a little Eshopps in-tank skimmer in my 20 gallon. It attaches by magnet and does a great job if the prefilter stays clean. A Coralife Super Skimmer handles my 90 gallon and it's in the sump. I ran it as a hang-on for a couple of years, but after a snail or two crawled up the return pipe and it overflowed, I moved it to the sump.

Thats a nifty little device
