What the heck is this??

[maroon2]

I keep getting this stuff on my glass and overflow box. Any ideas. A fish or invert that will eat it?

It looks like some kind of macro algae but I might be wrong.

Are you feeding heavily? What are your water parameters?

nitrate 0
phosphate 0
ammonia 0
ph 8.2

I feed once a day. Whatever my fish will consume in 5 min. I rotate between spectrum pellets, ocean nutrition flakes and frozen spirulina. All I have is a pr of gsm clowns, 2 bta, frogspawn, xenias, zoos, mushrooms and ricordea in a 75 w/ 30 gal refuge. I have been adding purple up to raise my ca which was 280. Coraline has gained lots of momentum since I started. Only been 2 weeks though.

Looks like a film algae or the start of a cyano outbreak. What is your water change schedule like? Amount changed, frequency and do you use RO/DI? If you are seeing an algae like that, your Po4 is not at 0 although most tests that we can get will not tell you of its presence. Additionally, if you did have a test sensitive enough to detect small amounts of Po4 the algae growth that you do have will consume it for fuel and not keep enough in the column to measure.

The white things look like foraminiferans to me.

Weekly 10%
yes ro/di
Just did a 30 gal chg and used phosbuster last weekend.
Its just those stringy looking things. Its def not cyano.Almost looks like a little plant/weed.

I have them in my overflow box and sump too. I did a reasearch and it appears that they are kind of filter feeder and actually a good sign of a maturing tank. So I wont touch them and leave them alone.

[DLANDINO]

Sorry, I was looking at the film and not the growths. I have those as well and seem to be some type of filter feeder.

Do they look like this? http://www.reefs.org/hhfaq/forams/ph...view?b_start=2

[Tunjee]

Looks like little tunicates. Sponges.

Yes kind of. But when I scrape it off the glass w/ my magnet it comes back in about 24 hrs.

[csmfish]

Okay, comes back in 24hrs is kinda wierd!?

It looks like a type of worm thwy usually only grow in low light areas like under rock and inside overflow boxes. It is weird they come back so quickly. There must be alot of them lingering inyour tank. They like it where there are alot of nutrients and stagnet water. If you clean the overflow well and produce some light and water movement there they shouldnt come back. However they are not bad for your tank but they will grow and usuall you will see some light yellow sponges around them.

Flow and light aren't an issue I'm moving over 2k gph in a 75 and I have 608watts of halides and T5s.
