Black black particles on nana's leaves

[samuelgoh]

Hi guys,

i got some black stuffs on my nana's leaves, not sure wat they are.
It starts growing along the edge then slowly, around the center also have...
Happens to new leaves after a while too...

All my other plants are ok less the java fern and these nanas.

anyone can offer me some help ?

Hi,

Does it look "hairy", if it is, it may be BBA.

My anubias nana also have that black stuff on the leaves, what I suspect is BBA remove or cut away those infected leaves..

BBA starts off like that. Do post a pix for us to confirm it though.

[samuelgoh]

kk, will post later tonight gotta work.
but the funny thing is , it only happens to my ferns and nanas, more on my nanas though, the condition of the ferns are improving.

i cut away the infected leaves, but the new leaves also same same after a while

[StanChung]

Probably because nanas are slower than ferns. I think that's the reason the hobby is moving towards concentrating on plant growth for algae control! [that would be credited to Mr. Tom Barr!]

[samuelgoh]

pics not very clear, but i hope u guys can make out wat they are, paiseh!

Too blur boss. Your camera focus on background. Try to put your camera further away from the subject and snap.

tried b4 bro, doesnt work on this one

i would say it looks like BBA...BBA always attack slow growing plants like nana and ferns.

[samuelgoh]

hmmmm then wat can i do to clear the BBA on the slow growing plants ?

[|squee|]

Two ways: preventive and destruction.

Prevention I assume you know very well already. Destruction-wise, take the plant out if you can, and put it in a container of water and overdose excel.

Otherwise overdose excel twice into your tank, or spot inject excel on the affected areas. I prefer spot injecting.

[samuelgoh]

hi squee, can u define spot injecting ?

[|squee|]

You can buy a syringe at any pharmacy in Singapore, and attach a short length of airline tubing to it. Use it to suck up some Excel, and inject it near the BBA-infected areas. The brief contact of concentrated Excel is enough to turn the BBA white 1 day later.

I would suggest you put SAE(siamese algae eater).These fishes are tried and tested with this kind of algae(BBA).also check your CO2,because in my experience I only got BBA attacks when my CO2 supply runs out for a long period of time.hope this helps.

actually this was wat happened previously =X
thanks lowell , squee and all others for ur reply.
i had since move the plants to a slower growing tank =)

OT abit anyway wat is the excel used for ?

Try to grow the Anubias under shade of another plant too. It's a slow grower. A little extra light attracts algae to the leaves. Mine growing in low light and with shade over it displayed nice jade colour leaves.

Meanwhile, you can read this article for more info and treatment: http://www.aquaticscape.com/articles/algae.htm

Anubias is hardy. So maybe you can try the bleach treatment as well. Just remember to wash thoroughly when putting back to tank.

Good luck!

i'll second KF. normally. do not place slow growing plants under direct light. attracts algae
