i am building a contrete 6x4x3 tank with 1 side glass viewing in my garage. Know any companies that do this sort of thing? located in ontario, canada. so i will be getting some very nice asian aros for it. thinking a super red, some RTG. Which are more aggressive and which should i try? will a 9 RTG be good? how many watts for heater? type of filter? btw it will be -30 degree celceius outside in winter.
