movement

[bristopher]

I been thinking about taking the 2- majijet 1200 out of my 75 gallon and going with a tunze. Do you think one tunze will be enough waterflow for a 75 gallon with sofites and lps or will it be to much. I have 4 inch sand bed. I read in another post that a wave maker needs to be used with the tunzes. They do not work withoout waveboxews or controlers?
Oh yea I plan to keep the hang on back power filters on back for surface water movement.
