maroon Velvet looking algea ?????

[BHAMR6]

In the last few months i've started getting this fuzzy maroon spots on my rock.. Its a darker color than coraline and its fuzzy. I thought one time i read something calling it marine velvet but cant seem to find it now. It's not slimey and it is really stuck to the rock you can not brush it off at all..

Just little maroon patches of fuzz.

I found a website on marine algae and they had a pic that looked just like mine and called it red turf algae...

Any way to get rid of it????

A few questions for you. What kind of lighting do you have? How old are the bulbs? Frequency and quantity of water changes? Running a skimmer? Carbon?

If you dont mind, what was the web site on algae you found, I would like to do some research.

I had a blanket of that kinda of stuff on a tank. eventually I harvested it, killed the lights for a few days, and insured my charto and other macros in the refugium were healthy.

I also started adding a teaspoon or so of pickling lime to my top off.

It went away, corraline started spreading in the display, other nuisance display algaes died off.

just my .02

Dual 250 watt Galaxy Ballast with Lumenarc mini reflectors and Radium bulbs. Bulbs are about 9 mos. old

Skimmer is a ASM G-3 w/th Sedra pump

15g water changes every 2wks total 30g a month

65g tank

Phosphates are un detectable on 2 diff. test kits. And i dont run carbon

Wicked Demon, I will find that site for you and post it in here.

Beaslbob, This stuff is growing on top of the coraline.. I think i will try cutting the lights see what happens

Its only small patches of this stuff but i dont want it to get out of hand

I would try to gently scrub with a toothbrush and siphon what you can and kill the lights for a few days. Starve it out while it is just small patches.

When I had the green turf I ended up putting in new bulbs (mine were about 14 months old), ran a carbon filter for a while, weekly 30gal changes (on a 150 tank), scrubbed and siphoned what I could, and wet skimmed. So far so good, no signs of the stuff for 3 months now.

Turf algae can be tough to get rid of. Lucky it is some what attractive. Since it is photosynthetic low nutrients commonly does not help all that much unless you go ultra low, less then .01 on a digital meter. If you can remove it now by hand and follow up with a kalk paste to kill root that would be best. The only other thing is to get a solid ID of it and locate a fish or invert that will snack on it.
Good luck

Mexican turbo snails will take care of it... It grows even with low nutrients and I had a problem with it in my frag tank. I added some turbos and red legged hermits and it was gone with a few weeks.
