algae ID. is this bad ?

[winereef]

I have noticed that this algae stuff has been growing for quite some time, and I was wondering if it might take over.

After a loooong search on other algae threads, I found just a bunch of confusion. so let me start with some tank numbers:

100 gallon display tank
6 VHO
30 gallon sump with liverork, skimmer and chaeto.
5 gallon chaeto scrubber
35 gallon refugium with liverock, some unwanted GSP and more chaeto.

water quality:
every 2 weeks 18% water changes.
tank has last been moved 9 month ago (re-using same water)
Ammonia:0
Nitrate: 0
Nitrite: 0
DKH: 10.5
Calcium: 440
PH: 8.8

Clean up crew:
4-5 Mexican Turbo
6-7 hermit crabs (red legs)
3 "cone" snails
1-2 other snails
1 emerald crab
1 Flat spider crab (i don't know it's real name)
1 peppermint shrimp
1 unknown shrimp

I also run a little bit of activated carbon too.

Now some pics:

If I let it grow, it will eventually start turning brown and appear more like a short velved , fuzz look. This stuff does not come of with extra flow or turkey barter. The only thing that I think works is the mexican turbos.
This algae likes also the light and does not grow that much in the shaded places.

At-least I know that in the worst case scenario I could get a boat load of mexican turbos. :uzi:

filamentous algae of some sort... do u grow any macroalgae? macros will out compete this crap...

 

[corallineadam]

and i have some breeding conch snails that will do a # on this stuff and breed til their population is in equilibrium with their food sources in your reef...

Oh Ya. I have a lot of chaeto growing. right now I have enough chaeto to fill up about a 5 gallon bucket.


Hm... breeding conch snails. that sounds like a good solution!
I need a breeding pair:love2:

 

[corallineadam]

do u turkey baster your LR before water changes? that stuff grows where detritus settles in my experience. maybe try bastering off the rocks to slow the growth...
sounds good on the snails, i will bring you 4 of them so they can trade partners if they like ill bring em to the club meeting for ya

get your nutrient under control too, Algea grow because of high nutrient level.

yes its true and do u dose any iron supplement?cut ur chaeto back (give the rest to reefers who need some) and dose iron

 

[winereef]

I thought I was already limiting the food. I guess not enough.

I'm noticing that this algae is only really growing in strong light.
maybe I should cut back on the light duration a little bit too.

No, I'm not dosing Iron yet. I know macro algae likes that stuff too.

Looking forward to meet you at the meeting and thanks in advance for those snails!
