Luckily (or unluckily) I don't really seem to have many babies right now. I am well versed in tearing the tank down from living in apartments where I need to tear down the tank every time I move. Last time I did it, there were tonnes of babies. I imagine I will still find a couple this time, but the reason I am planning on killing the scuds is I think they are out-competing the babies which is why I haven't seen many since the scuds really took hold.
My plan is to catch all the shrimp, put them in a pail with an airstone as suggested, tear down the tank, remove all the substrate, clean all surfaces, let it dry for a day or so, add fresh substrate, let it cycle empty for a day or two and reintroduce the shrimp.
For my plants, I plan to pull them all up, put them in a 10L bucket and let them sit in carbonated water while the above is going on. Maybe do one carbonated water change. If I still see any in the pail with the plants after all this, I will just dump them and get some new plants.
Does anyone have a good quarantine method for new plants? My current issue comes from the plants I bought at a local fish shop. Would like to avoid reintroducing anything.
