Hi,
Bought the big green killing machine for my 75 gallon. It worked at first in wiping out a blue green algae issue, I had. Took it out, since it is so unwieldy, and ugly. Algae came back; put the uv back in. Doesn't work as well as it did. Cleaned the sponge and impeller. Is this just a piece of junk, or is it my tank? Can anybody recommend a reasonably priced unit alternative?
