This spray bar works perfectly for our tank, love the adjustability of the flow. Our lady bettas are much happier with the reduced flow :)

This is the 2nd one I purchased. It keeps my fry fish safe from the filter and requires less maintenance than the sponge I was using on the inlet until I found and installed this.

looks great on tank. helps air flow and reduce tank temp. suggest buying 4pcs for more sturdy setup.
