Sean, the owner of this store is the absolute best! We came here 2 days ago, and have decided he is now our official LFS! Sean not only greeted us with professionalism, but also helped answer ALL of the questions we had, giving us extra tips & tricks to upgrade our new tank. Although we did not purchase our new tank from him (but wish we did), we did end up purchasing additional equipment from him, all of which were fairly AND reasonably priced. Sean's store has a great variety of coral & fish selection; if you want something but cannot find it in the store; he will help special order it for you. Even though we just met him 2 days ago, we already special ordered some stuff from him, and cannot wait until he has them in stock! Sean is personable, friendly, knowledgeable, experienced and an honest businessman. When we asked about something we needed, rather than pitch us a sale, he directed us to Amazon, letting us know his price was the same. Wow! We have been to many fish stores, and no one has ever directed us to Amazon! We will definitely be coming back and just wanted to give Sean a shout out. If you're in the market for anything reef related, look no further than Sean's Reef Factory US! Thanks Sean, and we look forward to seeing you again, soon!! read more

Hear me out. It's a cool place and all with a variety of softies, lps, sps, and beautiful fish, but who ever was working there was not welcoming at all!! I came in and no one greeted and I tried smiling at him, but he just looked at me so blankly it was like he had an attitude. Also, fish prices were very overpriced and some fish did not look healthy. But this was just my experience. I wouldn't recommend this place, however, if you want to give it a shot, then do it... Maybe you guys would get a better experience... read more

Shop is well kept, and corals look amazing! That's reason enough for me to keep coming back, but to top it off the staff/owner was knowledgeable and kind enough to answer my many specific questions read more

Reef Factory Us - Local Fish Stores Near Me - Placentia, California

Reef factory US IS A Fantastic store and Sean the owner is a really knowledgeable about the hobby and a really great guy and is a one stop shop has all you need for salt water aquarium hobby , read more

I was in the store for 30 min and was never talked to by anyone. Was not friendly or welcoming at all.

Small local business. Sean the owner is very knowledgeable and helpful. His systems are always very clean or sometimes he is working on them. However, it's just him working there; so it is a lot to maintain. Lots of acropora, acans, lps in general and wonderful fish. If you want something he doesn't have he is always willing to order you the fish of your choice. Been coming here for a couple years; I drive 30 mins from my house just to see what he has. He also does raffles periodically, I won an acropora frag of RR Angry Birds read more

This place has become my go to for the past year now and I don't plan to stop going any time soon. Shawn (the owner) takes truly inspiring care of the stuff he has in stock and is constantly getting in beautiful coral/fish/inverts that I've never seen before. It's always exciting when I get to stop by even if it's just for RO or salt water. So to finish this off. I just wanted to say how grateful I am for reef factory US getting my aquarium to the place it's at now. I couldn't have done it without you :) Oh I would like to add that Shawn is my go to guy for requesting specific stuff. He always gets it in at a good price and in good health. read more

The guy was rude doesn't know how to great would ask him questions about the fish would just look at you blankly like if he didn't want to help honestly I felt like he was discriminating us read more

Awesome shop, great deals and prices! Sean is great. Very knowledgeable and answered all my questions. He helped me setup my 125g display and does monthly service for my tanks needs. read more

Everything I purchased here was healthy and have survived. The shop is super clean and the setup is perfect. Great selection of fish and coral. You can even pre-order and they will quarantine until you are able to pick up. read more

Awesome and this is the cleanest fish store that ive been in. Everything looked crystal clear and would definitely buy from them again. Bought a leopard wrasse, green bird wrasse, blonde naso tang and alot of others. Owner gave me a discount since i got them all at once. read more

Friendly and knowledgable owner! Sean provided a lot of insight on how to care for my tank and tested our water to make sure all the levels were in the normal range. He quarantines any new fish he brings in and keeps everything very clean so the fish is healthy. He answered the 10000 million questions I had as well so thoroughly. You can tell he really has a lot of passion towards his sea creatures and store! read more

The owner of the store is fantastic! I stopped in to see if he had any aquariums on display for purchase and he did not. But we struck up a conversation and started talking about dimensions and he indicated that he could get me a custom low iron starfire tank. So I ordered the tank, then we started to talk about plumbing and now I have custom hard color coded plumbing being installed with the tank. He worked with me every step of the way from selecting equipment to how I wanted the plumbing to function. I never felt upsold at any point, and in fact I was the one who kept coming up with new ideas that I wanted for the tank, and he was able to make it happen. I highly recommend visiting his store and striking up a conversation if you don't see what you want. He can sell you brand name aquariums at better prices than you can find online, or you can go custom and get exactly what you want at a lower price. Not only has it been a pleasure working with him, he has taught me many things I did not know. If you are not having a question about what fish, corals, tanks, or equipment that you want, then you are not utilizing in my opinion what makes this store great. Great knowledge, great prices, and he is even installing it in my house for me. read more

Wow! To start off this review I am incredibly grateful to find a great fish store. It's about 30 min away and happily love shopping here then any other local fish stores near me.

Beautiful corals and amazing prices and also all his fish is quarantine so no need to do a quarantine before adding to your tank ! Overall 1 million stars review.
