I use compressed pine pellets in my tubs but then mine are in the garage, so I don't mind if they smell a little more. The pellets can also add to the dust, so I don't know that I'd use them in your situation. I know various people use baking soda in their tubs and haven't had any issues with it. I don't just because it's one additional cost and I really don't have any need to but you should be fine using it in the tubs. You might keep an eye on your babies, especially as pinks. Sometimes any sort of dust or powder can clog their nostrils and cause issues, so just be aware of that. I keep my pregnant females on aspen chips minus the pellets for just that reason, to keep the pinks from getting their nostrils clogged with the finer powder/dust the pine pellets can cause.
