3 or 4 primes on reefer 250 please help

[Waynerock]

Upgrading from a 170 to the 250 I have 2 primes on the 170 and grow SPS very well. Since I am invested in the primes already would y’all add one or two more for the 250. It’s still cheeper to buy 2 more than start over with the lights. Please help new tank will be here in a week and got to move everything over. Here is the 170

Gonna bump this with a new question
Since I have 2 primes already what about 36” aquatic life hybrid? Have they added a tank mounting system yet I cant hang anything ceiling is to tall.

I ran 3 primes and was not crazy about the coverage. I would go 4 or pick a different fixture
