From undersink filters that produce crystal clear drinking water, to commercial water treatment systems supporting 1,000,000 gallon public aquariums, large aquaculture facilities, industry, laboratories, retail stores, breweries, and everything in between; Buckeye has a successful nationwide track record of providing products of exceptional quality and unsurpassed customer service. 

Buckeye Hydro began as “Buckeye Field Supply” in the 1990’s when our founder, a Wildlife Biologist, avid scuba diver, and marine aquarist developed and sold products to other professionals. The company morphed over the next ten years and Buckeye Hydro was christened in 2012, reflecting a 15-year focus on water treatment. We’re staffed by less than 10, and when you call for help, it may just be the owner you speak with. Our company size means we can respond to your needs promptly and customize a solution for your situation. Although we manufacturer and stock numerous conventional treatment systems, we modify systems everyday to meet specific customer requirements. Nearly all orders are shipped the same day they are placed.  

At Buckeye, treating customers like family isn’t just a cliché – it’s our everyday practice. We’ll not try to “up-sell” you, and you’ll never be encouraged to purchase products or services you don’t need. In fact – you may find we’ll do the opposite and discourage you from buying something we think isn’t in some way appropriate. If you ask us about a competitor’s product, we’ll give you an honest answer. We’re exceptional communicators with a strong technical background – so whether you’re interested in buying your first water treatment system, want to set up a wholesale account, or need help troubleshooting a water treatment problem – we’ve got you covered!  

Nothing makes us happier than happy customers!


I want to thank you for calling me the other day when I emailed you about low pressure in my RO/DI system. Normally I might be compelled to let this whole thing go so that you don’t think I am an idiot, but you gave me good service after a sale and I feel I should update you...  Thank you for your help, and I am again very appreciative that you did not try to sell me a booster pump when I would have been easy prey for a less honorable salesman.

I just wanted to reach out and thank you for your assistance thus far! I saw the credit being processed for the cheaper shipping and UPS has confirmed it will arrive tomorrow. It is always a pleasure and I will continue to recommend Buckeye Hydro!

Just wanted to let you know that I received my order, and everything was PERFECT! Very well packaged! The quality of your product is phenomenal! I will be recommending your company to my friends!

I just wanted to thank you for going the extra mile to service your customers. I was totally messed up on a Saturday at 2:00 pm.... Buckeye answers the phone and totally walks me through it like he was standing there beside me! My R/O system is up and running just like that! Hat's off to you guys for being there for the customer! Not to mention that you have retained my business for life.
      James M. 

Wow, I’m speechless… Buckeye actually put the customer’s needs before profit. How rare is that! I can’t thank you enough, I will order online.
Wallace M. 

Does Buckeye ever close? That's the second time I ordered something on a Sunday and it was shipped that day. Thanks for the great service.
Bill S. 

I just wanted to thank you for extra fast service and shipping. I have been buying nearly all my equipment online since there is very little variety here in Iceland and top online sellers like you are hard to find!

I just wanted to take a minute to thank you. I got my filter today and it is making water as we speak. It is exactly what i wanted. It is always a pleasure to do business with you.
     Kurt W.

Well I want to thank you all. I was very surprised to get a call to sort this out so quickly. Most companies just don't care about their customers. This is a refreshing change! It also very helpful because once the work week starts tomorrow morning it would be impossible for me to deal with this again until next weekend. So thanks again.

I appreciate you guys standing behind your products. The consistently good comments I see about Buckeye on the web were one of the primary reasons I originally chose to purchase from you. Soon I’m going to need to purchase another RO system. You’ve proven to me that I want to make that purchase from you when the time comes. Glad to know I can “count on honesty, integrity, and quality” in dealings with Buckeye – just as your website says!
Shane S. 

Thank you sooooo much for being so patient with me. I studied to be a paralegal, not a plumber, so I’m sure I was a test of your patience.
Joyce J.

I called and spoke to you on Friday thanking you for the advice and your precise instructions. I have never had this type of result. A million thanks again. You're number one on my recommended list of vendors. I am smiling.
Paul M.

Thank you so much. The attention you have given has earned you a customer for life.
Jimmy M.

Thank you so much for the info. Your customer service is the best I've seen, even helping someone who bought a used rodi. I will buy from you when I need to replace my rodi just from the service that I've received.
Eddy P. 

I just want to thank you for the information on changing the check valve on my RO/DI unit. I have changed fittings, pressure shutoffs and everything else that I can think of and other people have suggested for 2 yrs now. I can't thank you enough.
     John M. 

I want to personally thank you for your professional work ethics, along with taking the time to answer my questions. I will recommend you to my reef group.
Robert B.

I have dealt with many vendors via internet and have had some lemons...it is refreshing to have you as a trusted vendor that I will continue to do business with for years to come. Sage advice and excellent service and a good value on a wonderful product.
     Tim C. 

WOW thanks for the lighting fast response!!!!!!!!!!!!!!!!!! You are truly the #1 in customer support and the best supplier for all RODI needs. Keep up the great work.
     John R.

You've verified all the good comments I've read on the website about Buckeye.
     Rick S.

I can’t even begin to say how much I appreciated that even well past what would be a reasonable time for me to have opened and inspected the shipment, you sent me a replacement part without hesitation. I am so happy to have ordered from you, and I will definitely recommend you to anyone else who is in the market. Aside from the fantastic customer service, it’s a great product that is running perfectly. Thanks so much!

 I recently decided it's high time I get an rodi system and having researched every "best rodi to buy" thread here on rc, I decided to go with buckeye and their "premium system", partially based on the overwhelming recommendations from many respectable rc members. I felt compelled to write a bit about my experience, as I hope it will help anyone who is "on the fence" about who to go with. The buckeye employee I worked with was very professional, very kind... and answered all my questions without making me feel like a "newbie." When I discovered that I forgot to order the fitting to connect the system to my faucet, they responded to my email immediately and made sure I had what I needed, and that it shipped out with the original order... that's service. The system arrived within three days of being shipped and was packed well... even came with instructions on how to set it up. According to many reefers on rc... the premium system is superior to anything in its price range based on a better initial 1 micron filter, and it's quality construction. I am a very satisfied customer at this point. ROCK ON BUCKEYE!

I must say that it is very refreshing to deal with a company that is as helpful and responsive as you are. Thank you for your help. I just placed my order for the 75GPD Premium ro/di unit. I cannot wait to get it!
     Jesse M.

 I recently purchased an RO/DI system from Buckeye. You provided outstanding customer service - very responsive to my initial inquiries, taking the time to talk with me on the phone to help me map out my ideal system, and providing feedback on my emailed list of system components and replacement/maintenance items to keep the system running for at least 1 year. I placed the actual order and sent payment via PayPal on Sunday during the Memorial Day weekend. My order was shipped on UPS the next day, a holiday for most of us. WOW! I got the system Wednesday of the same week, expertly packed… The unit came in flawless condition and setup was pretty easy with the included instructions. Thank you!
     Nick M.

All I can say is this is the fastest customer service I have ever seen. Thank you for the service its really nice to see a company that cares about its customers.
