Thanks, I haven't tested magnesium. I don't see anything on the zoos, but the orange ones wouldn't open when I first got them and I did a hydrogen peroxide/rodi dip for 30 seconds, then rinsed in salt water a couple of times before putting them back in my tank and that seemed to help. But they are not opening all the time. The snails do get on them a lot so that might be it. I could have them too high up as well, the orange ones seemed happier after I moved them down. I did see either a small ghost shrimp or a very large pod once but have not seen it since.
Also I can't listen to Anthony unless I ditched my bed for a fish tank cause I'm out of floor space in my room and well.... I'm not gonna sleep on the floor or in a tank..... LOL
I don't hang out in the living room so it would be a waste to put a tank out there. I'm happy with my cube, I just have to remember that it fills up faster and just get things that I really like.
