About
Marine Solutions has been a fixture of the St Charles, MO saltwater scene for years, and longtime hobbyists still point to owner Damon Weber's shop as one of the most knowledgeable marine aquarium stores in the greater St. Louis area. Walk in and you'll find rows of display tanks glowing with reef life — corals, anemones, clownfish, and naso tangs that reviewers consistently describe as healthy and beautifully presented.
If you're hunting for saltwater fish and corals for sale in St Charles, MO, this is the kind of specialty aquarium store where the livestock is curated rather than just stocked. The store isn't only a reef shop, though. Freshwater keepers come in for community fish, healthy live plants, and even axolotls — one recent customer credited staff member Nick with walking them through building a proper axolotl tank from scratch, while Elaina handled the aquascaping to get the aquarium ready.
That hands-on teaching comes up again and again: recent visitors single out Elaina, Nick, Sidney, Amira, and RJ by name as patient, personable, and happy to field endless beginner questions without making anyone feel rushed. What people value most is the depth of guidance. Damon has a reputation for spending real time on husbandry fundamentals — water chemistry, equipment troubleshooting, even helping a customer get an Apex controller and pump back online.
The shop also handles custom aquarium builds, professional tank setup, and on-site installation of complete saltwater systems, alongside dry goods, fish food, and supplies for ongoing care. Opinions on pricing vary — a few shoppers find it a touch high for a local specialty store — but most leave praising the selection and the team's willingness to help them succeed. For St Charles area reef and freshwater enthusiasts who want corals, clownfish, axolotls, and live plants available in St Charles, MO from people who actually keep tanks themselves, Marine Solutions delivers a focused, personal, in-person experience that a big-box store can't match.

Customer reviews
“Based on the reviews I was excited for this store. I walked in, they looked up and couldn't/didn't even say hello. I walked around looking at the fish for 20 mins... locked eyes with them a couple of times and no one came to assist. I walked out.... bummed because they had some freshwater fish and great selection on saltwater fish. I will say they had lots of healthy Freshwater plants and the fish seemed reasonably priced. However, the service is severely lacking.”

— Robin Carpenter5.0a week ago“Outstanding customer service that truly goes above and beyond! Elaina has been absolutely amazing throughout my aquarium journey. She takes the time to educate customers about different types of fish, the differences between freshwater and saltwater tanks, and how to properly maintain and clean aquariums. What stands out most is how patient, knowledgeable, and supportive she has been. As someone becoming a true lover of aquariums and freshwater fish, having Elaina walk alongside me in this journey has made all the difference. She genuinely cares, never makes questions feel silly, and always goes the extra mile to help. If you are new to aquariums or experienced alike, I highly recommend working with Elaina! Working with Nick at Marine Solutions has been an incredible experience! Nick has gone above and beyond to educate me about axolotls, the ideal tank environments to support their health, and everything involved in setting up an axolotl tank correctly. His knowledge, patience, and willingness to answer questions have made the process so much less overwhelming and so much more exciting. A huge thank you as well to Elaina for the aquascaping and helping get my aquarium beautifully prepared to soon welcome baby axolotls. The care, expertise, and customer service at Marine Solutions have truly exceeded expectations. It is clear they genuinely care about helping customers succeed and feel confident in their aquarium journey. Highly recommend!”

— Ben Abbott5.04 months ago“We are beginners and started with 5 gallon a fresh water tank. The young lady is very helpful and knowledgeable, she helped us select which fish to start with and what other tank mates and plants to consider as a starting point. Very happy with our experience and we'll certainly come back. Adding that we've continued going back to this store and everyone who works there have always been very kind to us and helpful with our tank setups. For sure will keep going back.”
