...good morning guys and gals!...
>...Liz, sorry I didn't get to your question yesterday...it was finish the cart decorations day...so didn't see your post til today...But I just finished watching the video...You probably have already gone to the store and back...couple things I do know about the BBA treatment...Vals do not do well with Excel....I have used both 3% H2O2 and Excel separately...I would take the water level down about half, turn off any filtration/air bubblers, and dose the BBA directly, using a syringe, with either product and let it sit for 15-30 minutes before I refilled the tank...usually within hours the BBA turned red and in a day or so, white....much like what Mass describes in the video... I'm glad to have seen the video testing both products together...I may try it if I need to....When I've treated it in the past, the BBA eventually comes back...I really prefer in my big tanks to have SAEs or Reticulated Algae Eaters...My sponge filter in the Congo tank was covered completely with BBA until I got one of each fish in with a bunch of cichlids...didn't really want them and had planned to take them to the next swap...that is, until 2 days later when I noticed the entire surface of the sponge was completely clear of the BBA...to this day that tank is devoid of any visible BBA...
...The real crux of BBA is the water chemistry of the tank....we read a lot about too much nitrogen, not enough circulation, etc....I don't spend a lot of time or concern with getting every parameter of my tanks "perfect"...aquatic habitats aren't that way in nature...naturally, rains (water changes), dry spells (water levels dropping), decaying organisms (plants, fish, invertebrates in my tanks), etc., all are constantly changing the water chemistry of the natural and manmade water features of the planet...Actually I prefer to use a natural means of removal with fish that eat it...it's going to turn up in your tanks when you introduce other plants and fish from hobbyists anyway...
SORRY...I'M PROBABLY PREACHING TO THE CHOIR HERE...! 
Side Note: I have seen BBA completely covering a large piece of wood in a display aquarium at Aquarium Zen in Seattle that was absolutely beautiful to me...as the water current from the filter moved over it the waves of the BBA reminded me of visions of wind blowing across a field of wheat...beautiful!
...Willie, i hope you don't feel anything from the fall yesterday...sometimes it's the 2nd day that pain shows up...glad you're okay...I guess yesterday was truly a hump day for you and Kobe

...and Barb, glad to hear your good news...the cat fall and the C-19...
...I'm preparing for our swap the next Saturday...currently I have 96 bags of plants ready to go...today I will probably do close to that many more...Most I've ever had...then tonight I'm going to pick up 53 fish that a guy is getting rid of as he downsizes...I will keep the Rummy noses and take most of the rest to the swap...I just want to get my money back on them...not after much profit...one of our other sponsor stores decided to run a swap later in the day after ours, so if I have any left over, I'll move over there...
...have a good day, all...
