Yeah, the only reason i use tank water is because my local water supply does contain chlorine. If it didnt i'd probbly just use tap water too.
I used Eheim Media, the first basket is "EffiMech". Thats what they call there ceramic rings. The second and third basket are both "EffiSubstrat" which is a sintered glass formed into little balls that remind me of the breakfast cereal "Kix". And of course the filter pads between the baskets.
On an unrelated and sad note, i experianced the first fish death in my 125 gallon since setting it up 2 months ago. RIP poor little angel fish.
