eheim pro3e media/ inline heater/uv/co2
I'm planning on picking up an ehiem pro 3e 2078 for my 55 gallon long. It is a south American tank with gbr south American bumble bee cats. Two angels and two needle fish. What media should I get? And what level should I put them at? Looking for an inline iv/ heater and co2. Any advice on brand and size. And is this too much in line?
