Ok.. Dont know if this is a question or something I am learning. I have tried the mod kits on 2 different wave makers 1. red sea 2. natural wave. one type of mod kit failed very bad arter a few starts. The other one I am using the kit is. shure flow by algae free.. This one is working very well becuse the propeller slides into the shaft. The old one I tried the propeller had a teat that butted up against the shaft in a indention. Has anyone else done this????
