How much flourite do i need for my 55 gallon?
So i am wondering how much flourite do i need for my 55 gallon tank? I am putting it under my current gravel, so i was thinking maybe an inch of the flourite and some gravel on top. I read the bag (15 pounds) and it said it was good for 2 inches but im putting gravel on top so i figured its different. Plus i figured i would come across the problem of my flourite being a different color than my gravel and thought what happens when i vacuum my gravel with my gravel vac wont the two mix together to make a weird color since the gravel is on top of the flourite, how can i avoid that?
