Im going to be doing this on my 100 gal this weekend. Hopefully everything will go well. Im going to doubledose, and make a filter for the siphon so I can run the water from my tank back to the sump, and filter out the dead worms and not loose water in the process. I think the next day I will do a water change, and see how the worms are doing and possibly do a single dose after 3 days depending. I also have a hot magnum Im going to use to run carbon...
