I have a 40 breeder and I’m currently only using the return pump as my only source of flow and have been looking in to getting a wave maker. I think I only need/want 1 for now. I see Jabao pp, ow, sow, and rw series they all look the same to me and cost about the same?? Which one is the newest and what would you recommend for my tank with mostly lps(doesn’t have to be a jabao)?
