there is some grass like algae growing on my glass. I just found out today that it is no good and I got worried. I would love to deal with in now while there is not much of it.

not the greatest pick but it does look like it feathers out like bryopsis.

I know, my camera is not the best at small objects. I will try to get a better pic later

Well, assuming you can;t get a better shot, nanoyed gave the best way to ID one from the other. Hair algae looks more like, oh, a blade of grass, where as Bryropsis feathers out. From that pic, I'm afraid I'd have to lean toward bryropsis, which poses a much greater threat, as it is very hard to neutralize. If it becomes more of an issue, you'll have to raise your Mg to combat it's growth.

Or a lettuce nudibranch, I love nudibranchs...

lettuce nudis are a waste of time on bryopsis.....use the MG method...

looks like bryopsis to me...being its on the glass only tho, IDK....i've seen stuff like this on my glass after cycles, and it wasnt bryopsis.

Yah my tank is cycling right now. Any chance I could just scrape it off the glass? or will that just spread it.

its not bryopsis then....try plucking and removing if youre worried, or just do a scrape....i'd just scrape and realize that your tank is gonna get ugly before it gets pretty.

your goal after cycle will be to just keep things humming and stable and clean.

no worries, like i said during the cycle wierd things like this come and go.

but do be careful looking out for algae as the months go by. do weekly water changes, use an ro/di unit, i run a BRS reactor with carbon and GFO and a skimmer. You likely dont need a skimmer tho.

look into all these things, and begin saving $$$ if necessary. also, you are your own best cleanup crew....pluck while syphoning every WC if necessary, and gently turkey base detrius out @ 1 time a week...

Can't you get bryopsis during your initial nitrate cycle?

I picked up some frags that had this stuff growing on it. I also had some other unidentified green algae that I wasn't too thrilled to see. I picked up a turbo snail and it knocked it all out in less than a week. This was one snail in a 6.5 gallon.

I have the same thing in my tank (also a new tank). I don't think that it's bryopsis as my dwarf ceriths and nerites will eat the stuff.


*edit* although taking another look at my tank it does look a lot like bryopsis. Guess I will see after several weeks.

Looks like Bryopsis.
But no whorries, this is what helped me a lot dealing with this pest:
get your KH above 12
buy some Mithrax crabs
lightregime back to max 8 hours (keep monitoring your corals carefully!!)
put a phosphate remover in your sump
remove the algea with a toothbrush but syphon the floating algea out of the tank otherwise they grow further

Hermit crabs, Salarias etc helps also, but nothing beats a team of hardworking Mithrax robots.

Good luck

I got a better picture of the stuff growing. I dont know if it is bryopsis, but the pods are all over it. You can see the white specs in this pic. The pods are also all over it on my glass too.

what's that? I have some on my glass..I have a lot pods everywhere too

thats nothing to worry about...not bryopsis...just normal new tank wierdness.

supermarlin, your advice is horrible...wtf.

I had the same exact stuff after my cycle. Basically instead of scrubbing the glass 2x a week I decided to let it go for 2 weeks to see how bad it would get. Well after the 1st week or so my glass had the brown/green film-like algae (not cyano) all over it. A few days later these little suckers started popping up where the film was at it's greatest. I only had a dozen or so on my glass. I tried desperately to scrub and vac them up. Some of them wouldn't let go of the glass as if they were cemented into it. I can honestly say that a few of them got lost somewhere in my tank.

Learn from my mistake, if you don't want stuff flying away from you then shut off all pumps before you start to vac . It's been 2-3 months and I haven't seen anymore of them. I do have a rather decent sized cuc with nerites, astreas, dwarf ceriths, and hermits. I'm not sure if they disappeared because my cuc was hungry or if they disappeared because my cycle was finishing. But either way I haven't seen trace of them. I scrubbed last night for the 1st time in 2-3 weeks and no sign of those buggers.

I got Bryopsis during my cycle, mine DIDN'T go away over time. I did the magnesium raising trick to get rid of it. That's my recommendation if it persists. Buying a purposed cleanup crew doesn't have a good working percentage of eliminating it, and, if you do eliminate it then you're possibly stuck with an animal that you can't feed.

that's good to know..i was panicking and planning to do massive water change...lol cos i have 10-20ppm nitrate

That is not bryopsis. Bryopsis has fern like leafs almost feather looking. If you want a positive id ask john maloney the reef cleaner dude. Wow you sure got some bad advice on this post. I would temove what i could but would not spend much of my day doing so.

That first pic definitely looks like Bryopsis, to me the second pic is inconclusive.

nothing inconclusive....its not bryopsis in the second pic.

Perhaps, but that doesn't mean the first pic isn't. The largest one little right of center in the first pic is pretty bryopsis-like.

I have had that in every new tank I have ever set up. Just throw in a phosphate remover and a few turbos and it will be nonexistant in 1-2 weeks.
