I am looking to add substrate to my 180g tank. I was leaning towards a fine gravel but looks like most people with Black Diamond Blasting Sand. There are tons of threads on the pros/cons so I am not concerned about that. My biggest question is around the required grain size to prevent it from getting into the filters. My tank is a 180g with FX5 and AC110s. My fish are piranhas so they will not be interacting with the substrate much.
My biggest concern is I don't want sand getting into the filters and ruining them. This is a risk with both considering the design of both filters. There is a tractor supply store by me and they have both the fine grain and medium for the blasting sand.
Cost is a point ($30 vs $200) and at some point I might want to do light plants which the sand is better for, but ultimately I am fining with paymore more money if it is better for my aquarium.
Any suggestions on black gravel is also welcome. I dont want crap black gravel that will lose its coloring and peel.
