This is a great statement and so true,Your tank is fairly young and it has been my experience that rock replacement is not needed tell around eight to nine years and then it is only a matter of exchangeing a few large rocks a year.I find vodka is benifical for sure in sevral aspect's but a healthy fish population pooping around the ol reef will do wonders too LOL Consider it organic fertilzer for your corals
