A checklist would be incredibly helpful. Something along the lines of:

(Example)

Step 1-remove cover
Step 2-test water
Step 3-run pump for ____hours
Step 4-vacuum to filter/waste
Step 5-add ____________
Step 6-test water again
Step 7-add____________

...and so forth. Please, if there is a generic order of operations, I'd love to get it right the first time. Thanks!
