Marine Solutions, St Charles MO

Best saltwater store in the St. Charles area! They’ve been there longer than any of the others around and truly know their stuff. The staff is incredibly knowledgeable and always willing to take the time to explain things and teach you along the way. Glad to have a shop like them around here!

I have been a customer for many years dating back to their Saint Charles location. Always valued experience and helpfulness compared to price as anyone can sell based on price. Purchased fish, equipment and supplies for all of my tanks. The owner has always been very helpful and supportive and helped when my son got started. Last week I discoved my 5 inch puffer was eating my fish. 3 clowns, 3 engineer gobies, one diamond goby and other various fish over the last couple of months. I called during the week and asked if I could trade for something and told they had room and could work something out. I brought in Sunday and had to run out and said I would come back later that day. When I got back I asked what I could get back in credit I was told $10 credit. I was kind of shocked considering the 2 previous puffers I purchased from them were about $60 minimum. It took me a while for it to sink in but told them I could not accept it. I would take my puffer back with me. I believe they would have easily sold this fish for $100.00.

I won't be back no matter what I need.or how long it will take me to get it from someone else. They lost a long time customer.

Nice saltwater fish store. They have a large selection of saltwater fish and corals and the staff is friendly and informative. They also carry rod's fish food which we love to use and you won't find it at Petco or any of the big box pet stores.

This place is stellar. The selection is incredible and the employees are kind and knowledgeable. I especially appreciated their PAR meter rental service. This is quickly becoming my new favorite reef shop in the STL area.

My go to place for saltwater fish, coral and equipment. The owner is very knowledgeable and always willing to help lead people in the right direction with their setups. They always have a very wide selection of fish and coral and constantly run weekly sales. They're also very good at assisting you with any equipment you purchase from them should you need help with setup or troubleshooting. The store also offers maintenance services which is a nice plus!

Seemed like a nice place at first, been waiting for their freshwater displays to be set up, but it’s been far too long most likely 2+ years and it has just become frustrating. I used to buy fish here every so often, but every time I bring them home a few days later, they would die from ich. Yeah, until I discovered some other stores, I realized that they have not ran any sort of copper system or any system at all to quarantine their fish. They are basically selling us sick fish, and it is very frustrating. I tried to ask questions and they made me feel stupid because they told me that I should know this stuff and that it’s common sense, most likely will never be coming back big disappointment but best of luck

Wow! What an inventory. This very well stocked store has an incredible selection of corals, fish and supplies.
The staff is super friendly and knowledgeable both qualities you should expect when shopping for marine aquarium inhabitants and accessories.
They can also set up a plan to do the maintenance for you in your home.
Highly recommend checking them out today!

Took advantage of someone new to the hobby. I had told the person working that I was looking to do a nano reef tank and they sold me something opposite of it that would eat corrals even after asking multiple times and then when I was told by my local store that the fish will eat corrals I contacted marine solutions and they told me sorry all sales are final but they would take it off me for free. Additional was over charged on a couple other fish I received from there when there was supposed to be a discount but you can’t see the receipt until after being charged and then they’ll say “all sales are final”. Very sketchy.
