water out-put mod
i put this NW-200 in a 10 gallon tank/sump the water output would spell/ splash over the sides.
1 i cut 2" off the black water overflow tube / outlet (because the wye make your spellway about 2" taller)
i got a 1-1/2" abs pipe and a wye & a 90 at lowes about $9.00 total
i glued the wye onto about 3" of pipe, in the and then just pressed th other pieces together.
i put silicone on the base of the wye and the some on the 3" piece . and stuck it inside the org tube.
it works great no splashing. their was a slight gurgle sound very slight. i put a air line hose (yellow in photo) into the top of the wye opening and the sound was gone.
