I have a 35 gallon paludarium with about 1/2 land 1/2 water. Right now I am doing water changes every day or few days, but i am looking to get some sort of filter/pump to circulate and clean the water. I am not sure what type of filter to get. I have a peptic and petsmart near my house and a locally owned poetaster a little ways away. Just wondering if you guys have any input as to what type of filter would work best. I am trying to stay away from internal filters. I am looking more for a canister filter type of thing. Thank you. Any inout is welcome.
