That's OK.  As long as the product is returned unused you will be refunded the full price of the product.  However, we are operating a business and because it was your mistake, you will be responsible for paying all shipping charges.  We had to pay UPS to ship it to you and you'll have to get it back to us to receive your refund.

That depends on several factors such as the type of filter you have (cartridge, D.E., or sand), how much the pool is used, whether the pool is screened in or open air, the amount of leaves or debris that get into your pool, etc.  All of these things help determine the frequency you should change your filter. 

For cartridge filters, the best indicator that we recommend is to look at the filter pressure gauge.  A new cartridge should have a pressure of 8 to 12 psi.  A good rule of thumb, is to rinse off the filter every time the pressure gets to 20 psi.  The speed of the water flow coming out the pool jets is another indicator.  If your water flow has slowed down noticeably it could be time to either clean out the pump debris basket, clean the filter, or replace the filter.   Another good indicator for a pool that gets used frequently is to replace the filters once a year to ensure your pool water flow is at it's best.  Having the proper water flow helps maintain the water clarity and balance. 

For D.E. filters, the grids typically last a very long time, sometimes 3,4,5 even 7 or 8 years is not unheard of.   A sign of needing to replace your D.E. Grids is seeing D.E. particles in the pool.  Typically, the grid covers tear with age and leak D.E. particles into your pool. 

If you have algae in the pool, it will almost surely ruin your cartridge filter.  No matter how many times you rinse off the cartridges after any significant amount of algae has been pushed into the filter, you will find it will be very difficult to get the cartridge to maintain a pressure under 20 psi.  If the pressue goes up to 20 psi or more within hours or days of rinsing your cartridge, this is a sign that it is time to get a new cartridge filter.
