I would look into a RKL with the net option... my tank e-mails me if something is a miss and I can just hop on the phone with the wife and walk her through what ever is wrong. I monitor PH, Salinity, temp along with my ATO... its not 100% but it helps to see looming disasters. Its aslo not a bad idea if it is an option, to have them know how to do everything alone. Heather can run all of the test, and dose (even though she never has had too) cean the skimmer and glass, all of it... In my notebook of records it is ALL spelled out if its off X dose Y and so on.
On the feeding its easier for me anyways to seperate into everyother day cups in the freezer I have a TON of little sald dressing tupperwear containers that will have enough food per container to feed both my tanks for 1 day. So I know exactly how much food they use and doen't over feed. Now if she is with me it doesn't help.
But we have 20+ animals to take care of so our pet sitters are normally other crazy people in the hobby that have some knowldge of what they are doing.
