I don't know how the Aquaclear powerhead looks but I use foam to distribute the suction on intakes a lot. Last thing I did was I bought a piece of foam that fits inside a cannister filter and trimmed it into a long rectangle. I put a slit in it and put it on the intake tube of my Fluval 204, replacing the strainer. I was afraid my Endler's babies would get sucked into the filter through the large strainer holes. Works great.
