I have a powerhead 802 wich i maily use for aeriation.This morning for some reason know matter how I adjust the tube connection to make the bubbles ,the head will not make any bubbles at all.
Its pumping a very good water flow just no bubbles.

powerheads increase areation by two diferent means, first by increasinc turbulence on water surface, increassing gas changes,
sencondly areation can be increased with an air input in the water flow (in some models) there are an air entrance (some times it has atached an air filter other times it dont), this entry point can be clogd (is this the right spelling?). Other alternative is (also in some models) the air and water flow, can be changed acording to needs, (for example 75% water / 25 % air , or 100% water 0% air) this maybe one other cause to your problem.
