hwchoy,

I do know what it is. I know u are from AQ and an aquascaper too!

I was into aquascaping but gave once BBA = black brush algae - an algae that will occur as little cute little mounds at first - looks cute at first.

Before long, it will swarm everything in the tank and I often had to overhaul the whole set-up... Got so fed-up.

Back to the waterlily topics... :offtopic:/>

wah, din know pleco can zap BBA, or else it would have saved me lots of time & effort. my usual approach to tackle algae problem is to 'normalise' the water chemistry as far as possible. i find it's not always a single approach that'll get rid of them. here's a list of thing i would usually do to stop serious algae growth, like algae bloom, BBA:

1. do weekly partial change of water abt 20%.
2. reduce duration of light to 4 hours
3. remove detritus, dead and rotted leaves from the tank, filter (always guilty of this :blush:/> )
4. snip off affected parts of the plant.
5. remove affected gravel also
6. add algae eating creature like otto, orange algae eater(can be aggressive), shrimps if possible. ah, now we've the yellow spotted pleco to add to the list
7. reduce feeding
8. increase higher order plants - easy growing types. once the tank is stablised, add your favourite or more difficult plants.
9. reduce fish numbers if overcrowded

i think that's abt it, lots of work hor?

My first post here. ROTFL. That was really funny yokogi. Plecos are funny things. I bought a dwarf ancistrus for my 20L nano. Guess what? That dwarf grew to be 4 inches in size.

Anyway, to zap BBA, you can use Glutaraldhyde. It's primarily a hospital disinfectant as well as an embalming fluid like formalin. Just squirt onto the BBA and it kills. Tinny doses are safe with plants and fish. Kills moss unfortunately.

Seachem Flourish Excel, an organic Carbon supplement for waterplants use Glutaraldhyde as its active ingredient.

Hydrogen peroxide (bought from guardian pharmacy) can do the same trick. Also squirt a tiny drop directly on the BBA. It oxydises the BBA and as a byproduct, it gives out a stream of oxygen bubbles as it work. However peroxide will also damage plant tissue slightly.

In both methods, turn off anything that cause water circulation for 5 minutes while you administer the stuff. This will permit it to stay at the correct spot to oxydise the algae.

Once BBA is dead, Mollies, shrimps and other "algae" eaters can finish off whatever remains.

Bad news is that if the conditions in the water is not corrected to promote rapid plant growth, the algae cycle will repeat itself.
