Hey guys, I wanna visually see the water flow/circulation in my tank will it be safe to add food coloring in my tank without harming my fishes? Or is there any special kind of dye for that? Thanks

I would also be worried about the color staining the silicone depending how much is used...

Back in the 90's there was some Ich treatment that was blue and once you dropped it in, it would turn the water blue(stain the silicon some too). I would have to say yes to some degree but I would advise against going out and buying any over the counter stuff without making sure it is safe for the fish.
