Aww BB I am soooo sorry to hear about your mom
Prayers go out to her and your family .
Just know that they can give an enzyme and insulin if your pancreas quits ... most can live a normal life on that .
BB yes the shrimp will also help with the lr
As for the CUC :
BB's Dad . Please do not add any thing to the tank just yet once you cycle and do your first H20 change and test again for stability you can add it .. Your clean up crew should consist of a few snails (nasserious, turbos and a few hermits ) be sure that if you get hermits that they have extra shells to move to for when they out grow thier current homes ...
It can take 4-8 weeks to completly cycle a tank it should look something like this Cycling just watch your perameters ....
and fall you want this at 0 (this is the start of your cycle) Ammonia
is the most toxic to fish
NitrIte will rise
and fall you want this at 0 this is the biproduct of ammonia
and is still toxic to fish
NitrAtes will rise
you want these less than 20ppm for corals still toxic but less so than the above 2 .You can do a H20 change to reduce .After your 1st H20 change monitor for an addtional week and add your clean up crew , continue with weekly water changes and monitor perameters .. Once you add something you will experience a mini cycle but once all go back to 0 you can add your 1st fish
about 6 -8 weeks from your start up is about right
