EasyFlow DIY Overflow with Accessories – 800gph

Designed for DIYers by DIYers. This system converts standard-non drilled glass aquariums, up to 125 gallons, into reef-ready systems.

This overflow is a high-volume system designed to convert standard non-drilled aquariums into reef-ready systems. Unlike restrictive 3/4″ commercial kits or unreliable drill-less siphon boxes that risk catastrophic floods, our system utilizes a dual 1-Inch High-Flow bulkhead connection* to ensure maximum turnover and absolute mechanical security. Every kit is bundled with a drilling template and instructions to take the guesswork out of installation, delivering the performance and peace of mind of a professional installation at a fraction of the cost.

⚠️ NOTE: Kit requires drilling, tools, and parts not included (dependent on your installation scenario, see below)

*To allow customization, bulkheads need to be purchased seperately.

Why Our Kit?

• Choose us over just a basic overflow box:
  • We include a template, lid, accessories and instructions for an easier install, consistent look and tested solution.
• Choose us over a drill-less siphon-based system:
  • Drill-less overflows rely on a vacuum that will eventually fail. EasyFlow uses a permanent bulkhead connection.
  • In a power outage, siphon boxes can trap air and fail to restart. EasyFlow is gravity-fed; as soon as the pump turns back on, the system resumes perfectly.
