directly? no. BlackBush Algea is actually hundreds of different possible species, some grow with excess b12, some grow with other imbalances. what this WILL do, short term, is help reduce excess phosphates that throw off your tanks balance. You still need to find the root cause that your phosphates went up. excess food, phosphates are put into some water pH stabilizing products. cheaper food can be high in phosphates. plant food, tap water. something is a source. this will help you get the levels down (in addition to water changes) long enough to fix whatever the problem is. BBA can then be removed manually by scrubbing decorations, a bleach-water dip for plants, etc.. i never do that because I don't want to kill my beneficial bacteria colonies, and I'm afraid of not rinsing enough and wiping the tank. but there are guides out there if you're brave enough.

APIPhos-Zorb Pouch, Size 6

Q: Can i mix phos-zorb and nitra-zorb together in the same media bag?

We would recommend to keeping the resin separate in case one resin becomes exhausted before the other.

Q: I have a 20 gallon tank, can I use this ?

You may use it, however this pouch is made for a 55gallon aquarium, you may not be able to get it to fit into the filter.

Q: I have a 10 gallon tank, water is not cloudy, but brown algae is growing. Weekly water changes already. Will this help?

This filtration media is for a 35-60 gallon tank filter. It would not fit in a small tank filtration system. I would test your water, move the tank away from direct sunlight. I like the bio orb media in with 2 charcoal filters
