Effective live bacteria seeding products do not need to be used on daily basis. It is an one-time thing.
If the beneficial bacteria start to grow in your filter media, there is no need to add any more bacteria every day.
However, we don't know Stability really work. For Tetra safestart, I have never used it more than once for the same fishless cycling. It always worked after I dumped the whole bottle into the fish tank on day one. It is meant to be used that way. Since you want as much bacteria as possible to start with, and the product start to lose its "freshness" as soon as the seal is broken. It is why we need to use the whole bottle at once. I always get the bottle of Tetra safestart rated higher than the actual fish tank size. For example, if I have a 10-gallon fish tank, I get a bottle rated for 20-gallon or more.
