It depends if you have a chiller for that then i would suggest keep it at 1.023 co'z when you compute it. It'll come out at 1.025 to 1.026, but for me 1.023 upto 1.026 is still a safe level for corals. And the most important are your water parameters in check, good lightings to penetrate your tanks depth, and good temp. Around 26degree to 27, max at 29 degree.
And for a 300g tank i don't think you'll be satisfied with 5 corals hahahaha. Enjoy reefing bro
