How do these work? does the tank need to have holes drilled for one or what? also inline heaters again can some one show me some and how they work? im assuming the heater goes inbetween the tank and filter?
just thought i would look into them as a possibility for my next tank
...Or how's about a filter heater combo, Such as the Eheim 'Thermo' Pro I filter, #2329. They cost about £240 & will cater for a tank size up to 600L (the dimentions you give are for a 450L tank).
I dont mind spending some money on them but thats just crazy!Take a look Here for one type
