Worm castings work well. Some people claim they need to be boiled first (to remove ammonia I believe?), but I have used them successfully straight out of the bag. You don't need to go overboard with it though as it probably does leach a lot of nutrients at first.
No heating cables are used. I keep the temp around 75 or so. I actually don't know the water parameters because I don't own test kits. I just use water straight from the tap. I may be lucky in that my tap water is good, but I also think many crypts are more adaptable to water conditions than we give them credit.
