building incubator question

[catfishrod69]

ok i will before too long be mating my P. regalis, and my B. vagans....i have read that the regalis are great mothers, and i might decide to leave the sac with her for hatching, but the vagans i will probably want to incubate...so my question is pretty simple..how? i have seen pics and videos of incubators....so basically a tub, with a damp bottom with a canopy to hold the opened sac, and netting to keep the slings from falling into water?
