Gravel change?

Question
If you want to change the gravel in a 90 gallon tank 4ft wide 1.5foot deep and 2 feet high.how many pounds of gravel and what is the best way to change it?


Answer
There is really no best way to change gravel. The best you can do is take it all out save as much water as you can.

If you want the gravel to look like a store display of fish. Such as the ones in our Petco make it look like the gravel is coming towards you. They recommend 5 pounds of gravel per gallon. If you want it to cover the bottom 2 1/2 bags of 25 pound gravel should work.
