Seapora Nano Overflow Box,Black

Seapora Nano Overflow Box is a popular product among customers. One customer asked how the product restarts after a siphon break from a power outage. The response was that the water level on both sides of the overflow pipe will remain submerged and prevent any air from getting into the tube, causing a siphon break. Additionally, regular maintenance would prevent biological growth that causes air to accumulate in the overflow pipe. Another customer inquired about the product's flow rate and the recommended return pump size. The product's flow rate is rated at 200 gallons per hour, and it can be set up on a pump that pushes 400 gallons minus some loss for elbow joints and head height. The Seapora Nano Overflow Box does not require drilling holes since it hangs over the top of the tank. Lastly, the appropriate size for the hose in the drain reservoir is 3/4 inch sch 40 PVC. In summary, customers have had positive experiences with the Seapora Nano Overflow Box. The product can survive a power outage without siphon breakage, and regular maintenance prevents biological growth, which causes air to accumulate in the overflow pipe. The product has a flow rate of 200 gallons per hour and can handle a pump that pushes 400 gallons with a 3/4 inch sch 40 PVC hose in the drain reservoir.
