What is this algae or sponge?

[Paul Fryburg]

Im so confused what this is grown on my live rock and sand.

I tried a week of no lights....did no effect

Dosing peroxide for a week..no effect

Parameters are spot on.

I hate it and its ugly. Has a green look to it.

Please any help

 

[lapin]

I have never seen that before
My first guess is a type of Calothrix which I have not seen in person either.

 

[Paul Fryburg]

Yea, never seen it before, thinkn about pulln out the rock work that has the most on it, scrubn it and peroxide spray. Idk

 

[Paul Fryburg]

Anyone eles please? Dont want my tank lookn so ugly

 

[Paul Fryburg]

Hwlp please...peroxide dosing has no effect

How old is the tank?

does it blow off with a turkey baster? Definitely not sponges.

How are you running your tank? I see no livestock. Do you have lots of flow or stagnant water? I’ve seen this type of growth in tanks with low flow before.

 

[Paul Fryburg]

Yes it blows off with turkey baster. Just fish swimming buy will knock it off.

Tanks about 1 yr old. 280 gallon tank. Lots of flow and no dead spots

Have lage yellow tang, large hippo tang, tomato clown and 6 line wrasse for live stock.

No corals or other inverts?

if it blows off, almost seems bacterial. Usually algae sticks to rocks and is more green.

Just fowlr thats all.

Have a 50 gallon sump and a 15 gallon refugium(always have trouble grown micro algae)

Bout to pull the live rock and scrub them all off, but w.e it is is in my sand bed too. Thinkn about stringing the sand up and let my filters pull the gunk out.

Spent alot of $ redoing this setup and now w.e. this bacterai/algae maken it look ugly

Maybe chrysophytes. I would google them and see if you get a match.

 

[dwest]

Chrysophytes?! Help me cure it?

Chrysophyta (golden-brown algae) The Chrysophyta are the golden-brown algae and diatoms, which respectively account for 1,100 and 40,000-100,000 species of unicellular algae. These algae occur in both marine and fresh waters, although most species are marine. The cell walls of golden-brown algae...

What are your phosphate and nitrate readings? Does sound like bacteria. There is product called vibrant that is a bacteria that does a wonderful job in my reef tank. Take some to your lfs for identification. If a form of cyno then chemiclean worked great for me. Both products had zero effect on life in the tank. Pods, shrimp, fish, LPS, and zoas....

On growing micro algea: I changed my so called plant light for 30$ and replace with hd380 or h380. Cheto went from a half fist full growth a week to like a gallon bag full and more per week. Unbelievable. The h380 does cost 10 times more but it really works. Nitrares are very low. Phosphate in .03 to. 06. And pods are happy. I have a mandarin to feed....

 

[Terry Mattson]

Btw. My sand is white and clean glass about every 4 to 5 days. Used to be daily. Tank is 11 months old. Hang in there ....

I had this same type of crap in my tank from the 3 month mark to about the 9 month mark of start up too! II don’t have any at the 10 month mark. All my parameters where on spot except for nitrate and pho. at 0 which I’m having another issue with that now ! Anyway I blew that stuff off with Turkey baster and siphoned off as well. Never had anything like that ever in my tank. I assume it was some bacteria deal.
I don’t think I had enough flow in tank so I ramped it up this month .
Don’t have any idea why it came or why it left !

 

[Paul Fryburg]

Thank u all for the replies.. def looks like chrysphose.

Gonna go at a hard cleaning tommorw see how that works.

 

[Paul Fryburg]

Well did a massive cleanibg, scrub rocks, cleaned sand and this stuff is gone..tank hasnt looked better!
