I fought with BBA in my low light aquarium for over a year with picking it
off and cutting off leaves etc.
All of my water parameters were fine except my phosphate level was high. I
started adding the phosphate removal sponges to my filter and also bought a
siamese algae eater and eventually all of the BBA dissapeared and
I haven't had a problem with it since. I think it was more the phosphate
than adding the alage eater.
Hope this helps.

I've been fighting a losing battle with hair/beard on my plants and black
brush algae on a piece of driftwood.
Tank is 130 litres, my nitrates are always within 5-10 mg/l, tested every
2-3 days, regular (every 7 days) 25% water changes, thorough and deep
vacuuming of the substrate and reasonably well planted with crypts,
swords,
ludwegia, bacopa, elodea, java fern and dwarf anubia.
Filters are a 1000 l/hr canister filter and a 700 l/hr internal.
Lighting is a 30watt bio-lux and a 20watt bio-lux on for a timer 12 hours
per day
I was using DIY CO2, but have disconnected it as it only seems to
encourage
the algae.
I have been reading about treating the plants using a 5% bleach solution
and
realise the trauma this must cause the plant, but I am desperate.
The only thing I haven't been able to find on the subject is whether the
dead algae falls off or whether it persists on the leaves and needs
removal.
Does anyone have any views?

Thanks!
