J&L notes compatibility with most overflows 18 in. and taller with a hole designed for a 1 in. bulkhead. Adjustable drainpipe helps fit different overflow heights. Air intake elbow helps reduce overflow drain noise. Modular dual nozzle connects to the 3/4 in. return line for adjustable return direction. Supports sump-style filtration on compatible pre-drilled overflow aquariums. Use one kit per overflow. Aqueon Stand Pipe Accessory Kit Compatibility and Planning Notes This kit is for compatible overflow-equipped aquariums and does not convert a standard undrilled aquarium into a reef-ready tank. J&L notes that the return pipe feature requires the overflow to have a hole drilled to accommodate a 3/4 in. bulkhead. Confirm overflow height, bulkhead hole size, sump layout, drain routing, and return plumbing before installation. Aqueon Stand Pipe Accessory Kit Setup Directions Confirm the aquarium has a compatible MegaFlow, All-Glass MegaFlow, or Corner Overflow system before installation. Dry-fit the drain and return components before final assembly. Install the bulkheads carefully and avoid overtightening. Adjust the drainpipe height according to the aquarium and overflow setup. Connect the drain line, return line, sump, and return pump using appropriate plumbing not included with the kit. Leak-test the full overflow and sump system with freshwater before adding livestock, salt mix, substrate, or rock. Check drain noise, water level, return direction, and all fittings before operating the system unattended.
