150watt over 30 gallon is close to 5wpg assume you have ok reflectors , and meta halide lightings are more intense than cf. With that setup, you will be high tech high growth and requires the same level of co2 (high bubble rate) and nutrient dosing to balance things out, otherwise algae will be the primary plants in your tank.
A sugar and yeast solution is simply not sustainable long term with that setup, unless you like changing the mixture bottles every week.
Get some nutrient sponge plants like hornwort and anacharis initially, even if you dont want them, float them around in the tank until you get a handle on the balance.
5WPG is not an easy setup....
