Keeping frag racks held down

[Shnetts]

Does anyone have any tips for keeping racks held in place?

What kind of weights are safe for reef tank use?

I filled zipper filter bags with ceramic rings that I had laying around. Kinda like mini sandbags to hold stuff in place

I use pieces of rock for racks sitting at the bottom, but you can also have magnetic racks on side walls

I tried to fix the rack to a media brick but my dang turbo is heavy enough to flip the rack whenever hes on the very edge, and he does it every single night lol

I wonder if i get a sheet of acrylic the size of the inside of the tank then glue the rack to that then the weight of everything else will hold it down
