Lift Tube Adapter/Strainer - PH 550, 660, 660R is rated out of 5 by 1.
Rated 4 out of 5
from One minor design issue It fits the 660R powerhead intake very well--snug. The fit into the strainer or lift tube of an ATI sponge filter is so loose that it really needs something else to make the fit tighter. However, I am using it without anything additional to tighten the fit because the powerhead is secured to the glass with a suction cup. It works, but it's not perfect. Since ATI is one of the top brands of sponge filters, any multiple-diameter adapter should be designed to fit them. It would only be one more of those plastic steps.
