Say you have a choice between an eheim heater and an Archea mini heater "the kind sold on ada's website" - and also, lets say that you're looking for reliability and quality and also for the ability to conceal the heater itself or at least make it not as distracting to the finished product of the tank layout when it reaches maturation... I have an eheim aquastyle 9, the led light fixture and filter is a corner 2 in one type unit which I plan to conceal with tall stem plants and possibly some kind of branchy driftwood.. Between these two heaters which one would you choose and why? I was thinking with the Archea mini heater I could place it beneath the filter of the tank and kinda squeeze the power cord alongside the filter somehow but I'm not sure if that will cover much...maybe it's too bulky to elegantly conceal that it makes no difference... The cost between the eheim and that heater are at a difference of a few dollars, which one is better in your' opinion?
