Hello I just found this site after searching all day for info on brackish water tanks. I really like this place and it has a lot to offer. I would really like to start up a brackish tank. I've had freshwater tanks for the past 15 years and want to try this. My biggest question is equipment mainley dealing with filters. What do you use? I'm looking at setting up 55 gal. I would like to go with some kind of eel setup but still researching what to put in it. Thanks.
