Warranty Coverage

Click Here to Register for Warranty

The Two Tides warranty through Pro Clear Aquatic Systems protects against any leaks that occur during the warranty period due to manufacturer workmanship. If such a leak occurs, a new and fully functional product will be sent out to the customer immediately.

This warranty also covers any small part breakages or failures. If a part happens to break or fail within the warranty period, either replacement parts or an entirely new product will be sent to the customer. Instructions will also be sent to the customer for how to properly and safely install replacement parts.

Photos of damages or failures as well as a throughly detailed explanation may be required to be provided to Two Tides before we can process a warranty claim and send a replacement product. This is especially important in the event of cracks or other more serious damages.

Shipping, Cancellations, and Exchanges 

If a Pro Clear product is purchased before noon on a business day, it is generally shipped out the same day. If a purchase is made after noon on a business day, it is generally shipped out first thing on the next business day. 

Because of this very short order to ship out time frame, cancellations must be made within the first few hours of product order, and FULL refunds, although mostly fulfilled, are not guaranteed (because of labor time, the fact that the product may already be fully packaged, and that shipping arrangements may have already been made). As a general rule, if it has been more than a half to one full business day from the order date or if a tracking number has already been created, then the order is unable to be cancelled. To ensure you get a full refund if you decide to cancel an order, email us ASAP at

In general, exchanges are not accepted for Pro Clear products and are not an option under warranty. Replacement products/parts are the usual option to go with.

Warranty Questions

If you have any questions or need clarification on the above mentioned warranty information or need to submit photos and a written explanation of damages/failures, contact us at We'd love to hear from you!

Warranty Registration Form

Customer must have filled out the online Warranty Registration Form for Pro Clear (linked below) within 15 days of the original purchase date to be able to claim this warranty. This will grant the customer an Entry ID Number which will be needed if the customer ever decides to file a claim for their warranty.

  • Click Here to Register for Warranty
  • It is strongly recommended that the customer fill out and submit the Warranty Registration Form directly following purchase to ensure there are no issues if a warranty is claimed later. We will send you emails about this to remind you.

Steps to Filing Warranty Claim

  1. Make sure you have filed a Warranty Registration Form online (linked above). Note that if this form is not completed and submitted within 15 days of purchase, the warranty will NOT be eligible. This form will provide you with an Entry ID Number. Once this Entry ID Number is distributed, the Lifetime Warranty is then in effect.
  2. Email Provide a brief explanation of the issue with your item. Some examples may be, “The product/package was damaged when I received it (and what types of damages)”; “The product doesn't work properly/as advertised”; “Parts were missing”; etc. Your email should include the following information:
    • Name:
    • Address:
    • Contact #:
    • Email:
    • Product name & item #:
    • Entry ID# (provided at warranty registration)
  1. From there, a representative from Pro Clear will be in contact with you to walk you through the rest of the process.

Keep in mind that all warranty claims are at the discretion of Pro Clear Aquatics. If you file a warranty claim, that is not a guarantee that it will be accepted.

Beautiful Tank, Great Customer Care
Hi Shane, This is Tyler with Two Tides. It’s extremely rewarding to see your tank all set up and running. It was also a great day when I heard from you that the movers did well bringing the tank up all those steps outside your door. You have a killer system going so far, and definitely keep me updated with how everything grows out. You’ve got my number. Cheers and happy tanking my friend To Your Success, - Tyler Moon

Absolutely, very glad we could resolve the leak and get your system goin before the weekend. Gotta love the contrast on that stand you made.

Let us know how the cycle on the new tank goes and talk soon.

Personable, Efficient and Smooth Experience

Hey Reno,

This is Tyler with Two Tides. Deeply appreciate the good comments, and I've got to say that it was quite a pleasure working with you. I'm very happy to see your clean freshwater system all setup and thriving, and you gotta love that vertical driftwood. Looks great man.

Don't be hesitant to call in with your progress, and yes hoping this is just the beginning of our working relationship. For now, wishing you great success and enjoyment with your new ProStar

To Your Success,
- Tyler with Two Tides

Great Customer Service

Hey Khalil,

This is Tyler with Two Tides. Thanks for your honest feedback, and your kind words on our service. I truly had a blast working with you, and even despite the plumbing holdups and all those video calls I'm just glad that we got to the end result of the beautiful tank you see every day.

That being said, we have taken your feedback seriously, and have just released a series of ProStar Plumbing Diagrams which can be seen in the product images for the ProStars, as well as a full Assembly Guide which can be viewed under the 'Assembly + Installation' tab. These will be emailed to clients while their tank is in transit so setup is very simple when the tank arrives. There are also videos in the works. We look forward to seeing this improve the experience of future clients.

Thanks for making us better Khalil, and keep us updated on how your discus and angels enjoy exploring the new tank!

To Your Success,

- Tyler with the Two Tides Team

Awesome piece of technology!
Hey Michelle, Very glad you enjoy your ProStar's design and that it's working well for your setup. Keep us updated on your system and happy tanking for many years to come To Your Success, - The Two Tides Team
