Ive been continuously using the same flourite I started one of my first planted tanks with 3yrs ago, and it is still hard as a rock. From my knowledge I dont think it breaks down very quickly at all.after about a year or 2 of use, does Flourite maintain its granular form or does it break down into mud?
Im still deciding on a substrate. and does anyone with a planted tank use a gravel vacuum?
It depends a bit on your stocking levels. If the tank is overstocked with heavy poopers, it might be beneficial to vac the gravel once in a while. Many of us have groundcovers which make vacuuming a bit difficult. My tanks are understocked, and I like my Marsilea IN the substrate, so I rarely pull out the vac. Plants seem to appreciate the fish/snail/shrimp poop additions.does anyone with a planted tank use a gravel vacuum?
I doubt it. It's a very hard fracted clay based ore (IE, rock). It will likely last longer than you do.i've used floourite for quite awhile and have never had any break down on me though i have heard of it if you use the vacuum cause it grinds it up
when you stick down in the flourite itself.
