How to choose the correct Complete Riser System.
All Complete Riser Systems are designated by 2 numbers (Such as 20x8 or 24x26). The 1st number is the diameter of the riser the 2nd number is the height of the riser system.
Step 1: Choosing the diameter
The diameter you need depends of the acess hole on your tank. You will want to measure the access hole at its widest point. Please use the chart below to determine the correct diameter for your set-up. NOTE: If your system has a square access hole please use the corresponding column.
|Your Access Hole|
|CRS Diameter||Round (Diameter)||Square (Side Length)|
|16||16" or less||11"x11" or less|
|20||20" or less||14"x14" or less|
|24||25" or less||18"x18" or less|
Step 2: Choosing the height
The height is up to you. Most of our customer choose the height in order to bring the lid a few inches above ground level. However you can go taller or shorter if you wish.
