Apparently you can increase this but only in ArubaOS 6.1 and above:
(Aruba) (config) #ip igmp
(Aruba) (config-igmp) #max-members-per-group <new-maximum>
I personally do not know the ramifications of increasing it past this number....

TAC got back to me on this.
Once the limit of 300 is reached new clients will not be allowed to join that multicst group.
Increasing that size is not recommended as it will increase the flooding of traffic (no report on what it would do to the controller)
Not sure how clients are removed though you can clear them by issuing a clear ip igmp group maddr <mcast_address>
