Whispers are good filters. The Bio Bag cartridge is economical and allows you to run carbon or other adsorptive media. The sponge will deteriorate in time and have to be replaced though.
These are good filters but I don't much like the media arrangement. It limits the types of media you can use. You can buy small bags, but that's a lot of trouble. Also, I had one on a turtle tank once and it had a bad habit of losing prime.
This is a top of the line filter and is, IMO
, far superior to any other HOB
filter on the market. The bio wheel gives you an excellent bio filter that is not disturbed when you change filter carts. The large media container allows you to run your choice of media. The separate bio pump and spray bar keeps the bio wheel turning. The only drawback to this filter on a SW
tank is that the spray bar will generate more salt creep than other filters. There is also the issue of nitrates being generated by the biowheel, but that's going to happen with any filter that is using bio media. My first choice.
This filter is similar to the Emperor in that it is high quality and uses a bio wheel. It doesn't have an extra media container and it depends on the flow of water coming out of the filter body to turn the bio wheel. It won't give you the flow that the Emperor will, but you'll also have less salt creep to clean up. My second choice of the filters you mentioned.
