I feed my plecos with Hikari brand sinking pleco wafers and I have a piece of driftwood for it to chew on. Your plecos died not because of BBA. It could be due to poor acclimatisation, or high nitrogenous products in the water that did them in.
Hmm. Conned by the Aquarium shop

An airstone literally increases the surface area of the water as each tiny bubble has its own surface area for gas exchange. Airpumps and live plants mix poorly.
There is no airstone. So no issue with excessive bubbles.
LLCC wrote:However, in tank powerhead filters are notoriously inadequate to do the job they are rated to do. They may have the water flow capacity suitable for your tank, but they have grossly insufficient biological filtrate area to match that capacity. Result is ammonia/nitrite in the tank that kills fish. Get yourself an Ammonia (NH3) and a Nitrite (NO2) testkit to test your water, especially 1 hour after feeding. You should not register any trace of either compounds. Failing which, you have found the cause of your Pleco killer.
Hmm. I will read more about the biological filtrate. Could be the cause of the death.

Keep surface agitation to a minimum, and your soil (if old) will generate the CO2 your plants need. Do not remove your lights unless the tank gets a bright indirect sunlight (eg siting it at a window). Plants can't live without lights.
Lights are needed and I will take note of putting in a timer.

Good news is that these are undemanding, fast-growing plants. Even better news are that these are cheap plants (cost $1 a pot here in Singapore) and are common. Best news is that these plants are local to SE Asia, so you can find them freely in streams and lakes.
Yes, they use to be available abundantly in the streams and drains but sadly most have disappeared due to the earth drain being repleced with concrete drains.
