So for my paludarium project (over in the Terrarium forum...) I am looking for a canister filter and am intrigued by the Cobalt E-X-T. Anyone use these? I haven't been able to find much info on them and am not sure if it is because they are new, they blow, or were just originally way to expensive for what they do (price now is just under $100). My biggest concern besides longevity/reliability is if the pump will have enough juice to pump/filter my aquarium. The tank will be a 70gal approx. 1/2 full with the actual filter underneath the tank. A 210gph powerhead or whatever it is seems like it might no be strong enough, but maybe I don't know what I'm talking about?
