help please! Noticed this the other day but its grown quickly since then.

 

Looks like bryopsis algae .

"quote from melevsreef"

Bryopsis is a weed that has frustrated many hobbyists. Eradicating this type of algae is difficult because it anchors itself well to the rockwork. Very coarse in nature, this plant attracts any type of detritus which it then uses to create its own nutrient base substrate. Plucking it by hand is possible, but some bits will be left behind. Be sure to use a turkey baster to blow out any accumulations to help starve this plant of nutrients. Snails, Sea Hares, and Lettuce Nudibranchs are all known to help decimate bryopsis.


also.. do you run GFO? What are your phosphate levels?

 

thanks for the fast response. phosphates are at like .25ppm and no on the GFO. What would you recommend?

 

I would recommend removing what you can, without spreading it. Running GFO does help to remove phosphates, which is what algae needs to live.

 

You can also bump up your magnesium with Kent Tech Magnesium. Bump it up 100/ppm per 24 hours until you get to 1800. Go slow and you should not see any adverse side effects, if you do it will be to snails.

 

cool. Thanks for the advice. Just tried removing them. Mostly they just disintegrated. I'll keep an eye on them and do the recommendations. Thanks everyone
