No it is self contained. A hose to feed it and a hose to return to the tank. The motor on top drives a pump. You do have to fill it with water for it to work.
What do you mean by other options? On the filter or to clear up your water? I tried a lot of things to clear mine up and the diatom filter was what I found to work. I probably had the bloom for over 4 months. Maybe even 6 months. Bought a new UV to combat it, with no results. So, I do not know of something else to do. Microbact7 could help, not sure, but it seems that is just another strain of bacteria. Maybe a chemical like peroxide will help, but it may also wipe out your tank. Not sure what else to do, that is why I opted for the DE filter. Took me a while to get one, (I wanted a used one) then I needed parts, got the wrong parts, ordered again, then I needed more DE. So it may be best in hindsight to have bought a new one rather than a used one, certainly would have been cheaper in the end.
It was nice to see my fishes again after all that time, rather than just the occasional ghost swimming by the front of the glass.
