Why Buy From ReefBum?
Number one, I have been a hobbyist for over 25 years who wrote a book on reef keeping best practices……so I can leverage this wisdom to provide expert advise on equipment purchases.
Secondly, I am the sole proprietor and employee of this company who can be contacted any day of the week to answer your questions about equipment sold on reefbum.com. Therefore, you will always deal with the same person who actually uses the equipment you buy. And if I don’t have an immediate answer I can reach out to the manufacturer to get an answer….I have direct communication pipelines with all of them.
Yes, I am a “mom & pop” shop that will not always beat pricing from the “big box” online reef stores. But think of me as your personal reef tank concierge who is always on call to help figure out a problem or just chat about reef tanks. Now that’s priceless!
