My 200lt semi planted aquarium
Hey guys I'm hoping you can help me I'm running a fluval fx4 on my tank as well as co2! It's been running well with a internal fluval heater but I'm getting to the point that I wanna run an external/inline heather. With the filter i replaced all the pipe work from the horrible black pipe. So the question i want to ask is can anyone please help me with ideas about heaters that will fit the pipes and that will heat a 200lt tank?
