So I have just won a 'Clean Up Crew Package' from a LFS and was wondering if it is smart to accept it given the size of my current CUC (see photo below).. 
They are wanting to add roughly the following;
5x Turbo Snails
3x Nassarius Snails
3x Crowie Snails
2x Astraea Snails
2x Trochus Snails
3x Stormbus Snail
2x Peppermint Shrimps
The tank is roughly 3 months old and is still currently going through the 'Uglies'. The lights run mostly white during the 6 hour peark period (which I suppose encourages algea growth).
I currently do one heavy feed per day with Flaked food for the 3x Fish (I plan to have 3x more) to make sure there's enough detritus for the CUC to get their share.
I do not have a proper sump as I am running a Red Sea AIO system, so sumping them isn't really an option (I've heard people have issues with CUC in the back of AIO units).
TLDR;
So honestly my question is: should I turn down the prize I won? Is my tank large enough to have that many CUC? Are there changes I can make to further help sustain that size population?
Any help with be greatly appreciated.
