With the recent influx of 3D printed products hitting the market, there have been a handful of innovative products. The new NemProtect stands out as a really great answer to the needs of small fish and anemone keepers everywhere. Flow is a critical element in reef and anemone tanks, but powerheads pose a serious risk to certain delicate creatures like anemones. Not only can a powerhead destroy a prized anemone, but the result can threaten the entire tank if not caught immediately.

One of the most popular solutions for in-tank flow right now is the IceCap 2k Gyre Pump. While its stock foam guards can keep anemones from getting pulled into propellers, they clog quickly with detritus and reduce flow dramatically. The new NemProtect guards create a greater surface area for water flow while simultaneously diffusing the intake suction and increasing distance from the propeller blades. The Nemprotect easily slips onto the Gyre propeller cages and stays put via friction fit. Anemones can't get through the numerous tiny holes, and the high surface area of the guard avoids clogging and reduces flow loss. The guards also serve as flow deflectors, minimizing surface eddies that can suck in air and splash water. The result is a long-lasting, low maintenance anemone guard that improves overall flow in the system; a win-win!
