Important: This cover is custom-made. You will need to provide overflow measurements when ordering. All measurements will be confirmed with you by our team after purchase before production begins.

How to Provide Measurements

Since every tank’s overflow box can vary, we’ll need your measurements to ensure a perfect fit. Please follow these steps when placing your order:

  1. Measure the Outer Dimensions: Measure the length and width (left-to-right and front-to-back) of the overflow box top opening, where the cover will sit. Record in millimeters or inches.
  2. Check the Corner Radius: If your overflow box has rounded corners, measure the radius (curve) so the cover matches properly.
  3. Measure the Height Clearance: Confirm how much space you have above the overflow box (to ensure the cover can be lifted off easily).
  4. Take Photos (Optional but Helpful): A clear top-down photo of your overflow with a ruler or tape measure in the frame helps us confirm accuracy.

After you order: A Fragtide team member will contact you to review and confirm your measurements before we begin production.

Why PETG?

PETG is one of the most reliable reef-safe materials available. Unlike acrylic, it won’t crack or warp under humidity, and unlike ABS, it won’t leach chemicals that could harm your livestock. Strong, durable, and clean in appearance, PETG is built to last in demanding saltwater environments.
