OK, so moving on to plan B. I am finding the control of BBA extremely
time consuming. It's the most tenacious algae. Hell, I don't even get
green spot algae anymore. BBA grows very slowly, but it still bugs me as
it excludes me from keeping very slow growing plants.

I have a spare 110 litre aquarium I wish to move all my fish into from
the 330 litre, temporarily. Given that the main tank will have no fish
in it, how far can I push a treatment to guarantee a kill of BBA and
still give the plants a fighting chance? For example, how many days of
blackout would be required, 3, 7, 14 days?? I presume I'd stop all CO2
for that period.

Plan C is to strip the tank.

Two cc/gallon of Hydrogen peroxide will kill it. Get ready for big
water changes as it sloughs off, the H202 will also kill the good
bacteria and you'll need to cycle your tank again. Get your tank
as clean as possible before doing this as it will react with any organics
(ie, dirt, mulm etc). You may need to do this 2-3 times every other
day. But I have done this to eradicate (not control) red algae
(which is what BBA and black staghorn alage are). Green alage are
less affected if at all.

Fish, shrimp and msot plants are unaffected. Ones that may be hurt
are hornwort and swords. Crypts seem immune to the stuff.

Aquarium pharmecuticals Algae FIx also works but is toxic to
all invertebrates.
