Yes, you should definitely move your PFRs to another tank for the month it's going to take to cycle with Aquasoil. They should be fine in a breeder net, as long as it's covered and they can't escape. You'll just need to be sure to feed them and maybe put some moss in the net with them.
If you can't find a good price locally for the AC30, Foster & Smith has them for
$20.99 right now. Once you factor in shipping, though, you may be able to get them cheaper locally.
