Very knowledgeable and professional people. They aren't just trying to pawn products off to you. They let the customer decide with the amazing advice that they give. Every fish tank is crystal clear and the overall establishment is especially clean.

These guys are the most professional aquarium service company we’ve worked with on Long Island. We had a custom aquarium installed by another company and it just never looked great. We tried another aquarium company with good reviews, but we still had a lot of the same issues. We called Fluid Dynamics as a last attempt to get things right and they’ve been great! Everything in our reef aquarium is thriving and growing finally! Highly recommend these guys for any of your aquarium needs. They never pushed anything on us, their billing is fair, and they’ve been patient with all of our questions and concerns. We were almost ready to get rid of our tank, but this company saved us a huge headache!

Extremely knowledgeable and nice people. Excellent stock of fish and supplies. I’ve had a fish tank for almost 50 years and I’m looking to replace my tank. Brian couldn’t have been more helpful. He even took a working filter apart to demonstrate it’s features to me. They also offer custom tanks like on the tv shows. I highly recommend checking them out for aquarium needs.

It was an absolute pleasure talking to the friendly and knowledgeable staff at Fluid Dynamics.

I am a beginner and walked in with a rough idea of what I wanted and a million stupid questions. Jared was patient and accommodating. I went in for sand and some plants and ended up with what felt like a free consultation from an expert in the field.

The plants were all submerged and healthy (unlike many other stores) and all the tanks were clean and organized.

I will be a regular customer for sure.

The best customer service! I went in here looking for live plants and they walked me through 5 different tanks stocked up with options. I was also looking to add spider wood and a mystery snail - being a beginner their knowledge really helped create my finished product! They have great inventory and the fish are clean and healthy. Considering how friendly and welcoming the crew was, this will be my go to shop!

3 Unique Aquarium Design Ideas for Your Long Beach, NY Home

If you’ve been thinking about bringing fish or a custom aquarium into your Nassau County home, rather than going with a run-of-the-mill, do-it-yourself pet store fish tank, if you really want to make a bold statement, consider having a professional Long Beach, NY aquarium service create and install a custom aquatic habitat for you instead.

Here are some unique and amazingaquarium design ideas that a professional can create that will be sure to delight.

A Bathtub Aquarium

No, we don’t mean turning your bathtub into a fish tank (though it’s certainly possible and would be neat if you have an antique or unusual tub that you don’t intend on using); rather, by a bathtub aquarium, we mean having a tank installed near your tub. A Long Beach, NY aquarium service can design and install an oversized – or even a floor-to-ceiling tank – on the wall across from your bathtub.

A Headboard Aquarium

A professional Long Beach, NY aquarium service can install a tank in the wall above the head of your bed and fill it with vibrant fish, coral, and aquatic plants, and illuminate it with a blue, purple, or black light. Flank the tank with custom, built-in shelving, and this unique aquarium design and you’ll have a functional and beautiful piece of living furniture that will be sure to make your bedroom more inviting, and that will create a calming sleep environment.

Contact the Premier Long Beach, NY Aquarium Service

We’ll not only design and install your fish tank, but we’ll also fill it with a stunning array of aquarium fish, and because we offer fish tank maintenance services, we’ll ensure your salt water or fresh water tank continues to thrive.

An Aquarium Table

When topped with a thick piece of glass, you’ll have a 360-degree view of the aquarium fish, aquatic flora, and decorative elements in the tank. A coffee table, a side table, a dining table; no matter the type, the style, or how it’s used, an aquarium table will surely add visual appeal to your Nassau County home, and will undoubtedly serve as a conversation piece.

FAQ

How Often Should I Service My Aquarium?

You should perform a partial water change in your fish tank around once every two to three weeks, or more often if you have a lot of fish. If you have to change all of the water in your fish tank completely (a full water change), only do it when it is absolutely necessary.

How Many Years Does An Aquarium Last?

Glass tanks typically last between 15 and 20 years if they are made of quality materials. A high-end glass tank can last more than 25 years if properly maintained.

How Often Should I Vacuum My Gravel?

You should vacuum your aquarium regularly, whether once a week or once every other week, as part of a good maintenance routine. Ensure that all your decor is removed before vacuuming.

Is It Okay To Change The Water In My Aquarium Every Day?

You can change water as often as you like if you dechlorinate properly and keep the temperature constant. Water may be changed daily by professional fish breeders to remove excess food and promote maximum growth.
