Title: Good but some issues
Review: It's a good filter. Does what it says, reliable, keeps the tank clean and the bio wheel does the job removing ammonia/nitrites. Had issues with buzzing/humming sound at first. Marineland tech support was very helpful, but even with replacing all moving parts, still had annoying hum. I ended up removing the part that splits the water to the spray tube and then it was very quiet. Works fine. Spray over bio wheel not really needed anyway since biowheel is wetted from below by water flow under it.
