I'm working on redoing a 55 gallon aquarium at an elementary school. I bought an undergravel filter for it. So my question is how many pounds of gravel do I need for this tank? I was told two 25 pound bags, then I was also told to put an inch and a half of gravel per gallon of the tank size (that sounds way off lol).
Can someone please help me with this? I want to know the true amount of pounds of gravel that I really need.
Thanks so much!
