When to add a cleanup crew

This is Day two and I have started the tank with a mixture of a wet live sand and a dry live sand and dry live rock....The water is all made from Coral Pro Salt and have it @ 1.025. I added a pinch of fish food like I had heard of doing every other day to establish a cycle. How hardy are the cleanup crews and when do I add them ? I am in no rush.... Just wondering if they'll help during initial start or not ( I've seen both ways on video). Also have the heater set at 79-80 deg F. I've also heard diff ideas on lighting times from 0 to 3 hrs p/d to to hinder algae growth. Just don't trust the pet stores or their water, live rock etc....If you saw their tanks around my area you wouldn't either !

 

I would wait till after the cycle to add the cleanup crew imo.

 

I would only add a cuc after you begin to see some algae growth, typically 1.5-2 months in. You can add smaller hermits but snails need some algae growth to eat otherwise it's a slow starvation.
As stated above and only after the cycle is complete.
