“Dr Reef” has some of the worst customer service I’ve experienced. I don’t believe he’s a doctor in anything Marine related. Would have a million excuses under the Sun on multiple shipments about why they were delayed. Always something, then he always plays the “I’m doing it for the love of the hobby” card. Acts like he’s doing you a favor even though you’re the one paying him. I tried him twice because of cheaper prices, one of the packages smelled like straight death when I opened it and there weren’t even temperature extremes or shipping delays. I’ve only used TSM since and had great experience with their QT fish, though the selection is thin sometimes; the quality is superb. Then for CUC I usually use reefcleaners.
