fluval evo/tmc reef pump compact 500

Hi all I’ve recently purchased a new pump for my Fluval evo 52l it’s a tmc reef compact 500 It has adjustable speeds from 10% to 100% with a overall flow rate of 500L/H I’m pretty new to the hobby and I’m unsure of the correct speed is acceptable for my tank with just 2 clownfish and 3 hermits...
