When should I change the sand in my filter?

You should change the sand in your filter every 5-7 years. You can generally tell that it is time if your pool water is not as clear as it normally is or when you notice the interval between backwashes is shorter. You can use > this guide to walk you through it.

What does backwash mean

After a period of time, the contaminates in a sand filter start to clog the sand to the point where water flow is significantly diminished and the pressure gauge rises 8 to 10 psi above normal operation readings. To clean out the contaminates, you have to backwash the sand. This guide shows you the steps in backwashing a filter.

what size sand filter is best for a 30x30 free form average depth 4&1/2 ft

Hi William, Your filter is sized based on the actual GPM of your pump on your pool. To calculate the GPM of your pump you will need to calculate the TFH (Total Feet of Head) and use the performance chart of your pump to find of the GPM. You can view our How To: Size a Pool Pump guide to instructions.

(5 out of 5 stars) Great Filter

Pros: Ease of use
Cons: None
This filter keeps our pool sparkling clean. We backwash monthly, and only then because we want to. The filter rarely gets to 5psi above the starting pressure. We decided to use Zeobest instead of sand and have been very impressed.

Pros: Less maintance
Cons: N/A
I installed this sand filter as a replacement to a D.E. filter. I am so pleased with its performance compared with the D.E. I will never go back to a D.E. filter. Also used Zeobest sand.
