Simple, inexpensive, adjustable and easy to clean. Great for use during isolation and treatment. Can house heater and pump. Come in two sizes and will fit a gyre. If your pumps aren't near the top of the tank, buy two and double net the one. Magnet holders on pump will hold incase suction cups give. Not hard to find. Beta breeders. Aqua one also make the same type. Keep seeing pictures of nems during treatment when most vulnerable with uncovered powerhead and heaters. Scares me. My 16 inch heteractis magnifica sat Infront of my jebo for a week on one of these. You need a little space around powerhead so tentacles don't get sucked in due to reduced suction. Mesh directly on powerhead has a greater chance of sucking something in.
Now if they only made them in clear plastic.
