FA rake This is what I use for mats.
Moving lots of air! Thanks for video.
I leave ropes on mine so I can pull diffusers for service.
Snrub, please excuse my ignorance, but what do you mean by "mats"? Matala diffusers? mats of algae? I expect you mean the latter, as that is what you are using the big rake to pull in, but I just want to be clear on what you refer to.
I also included a rope that is attached all along the air hose out to the handle cutout of the cutting board diffuser base platform. I ran the rope along the hose so I'd never have to pull the on the hose itself directly.
The visible cross rope that runs connects to a loop at the diffuser itself was only used to carry it out to the center of the pond and lower it. I can and will pull that out if necessary. No harm no foul leaving it there, but not necessary to have in there either.
