Hi Susan. Not sure how your thread came to my attention but spent the last week reading it from the beginning. Quite an adventure you've had. Glad most things are doing so well.
Couple thoughts on some of the issues you've mentioned.
1. Trident - have you gone through the Troubleshooting guide on Neptune's site? Usually a No Water Sample error can be cleared by unplugging the Trident then plugging it back in after a minute or two. I believe you said it was hard to get to the Trident, but you can unplug it from the EB832 or 1Link if you're using as it doesn't have to be unplugged from the back of the Trident. I can't easily get to mine either. I've been using mine for 3 years or so with only a similar error a couple of times.
2. Sand sifting gobies are really hard as they don't often eat the prepared food we feed our tanks. They sift the sand to get the food, i.e. critters, that live in the spaces between the sand grains, so very tiny food. They may east some algae off the sand grains as they shift sand but your sand is pretty clean so probably not much food there.
I'll keep following along.
Mickey
