Math seems good. 300 gal per hour x 2 = 600. 600 divided by 75 = 8. I don't usually allow for rocks and substrate in the calculation, if you do; turnover closer to 10. I'd say you are okay either way - subject to fish quantity and frequency of water changes. I use AquaClears so cannot help on other brands.
