Method reminders
Prepare, add gradually, observe
How should this be introduced?
Prepare as appropriate, add a small amount first and watch livestock and water clarity for 24-72 hours before adding more.
Is natural variation normal?
Yes. Botanical and prepared aquarium products can vary in size, colour, shape, texture, tint and breakdown speed.
Does this guarantee water parameter changes?
No. The BBA method is deliberately careful: products can support a route, but they do not promise instant pH, GH or KH results.
