At the very least you can save the filter cleaner, alk increaser, and Ph decreaser, and the foam(reducer), it's not unique for Baqua. Even if it has their name on the bottle.
Not sure about the water clarifyer. The test strips will still work for checking Ph, alk, and Hardness, if you want.
The only stuff you might want to get rid of is the sanitizer, shock, and waterline control- The 1,2,3 crap.
You may get someone saying not to use Baqua's filter cleaner with dicholr or bromine, but that's BS.
