Good golly wogs... a 125g tank and an RO unit that only does 10g/day?
Shoulda got a typhoon3. They do 75g/day RO+DI. ***)
I do a 25g change once per month on my 75. Sometimes after 3 weeks. Works out well.
And about the cleanup crew... You don't need to add ANYTHING else to your tank for a few months. Let it get well established. You'll be glad in the end.... and so will any "new inhabitants" you decide to add.
