Have a 29 gallon set up and would like a hob power filter, but am confused on which one to get. Have a cascade 500 canister, but am not happy with it. Water is always cloudy and it is a pain to take apart and clean, and when I hook it back up, a lot of stuff comes out of it, even though I clean out all hoses and canister itself. Think a hob would be easier to clean and manage. Would like to know which one would be good for the size tank I have. Also have green water a lot and would like to get something to fix that. Help!! Any suggestions would be great!!
