The pump run time depends on a number of things including pump flow capacity, pool size, filter capacity/Flow rate, etc. The normal rule of thumb by the "pool men" is for them to claim ". . . you need to run it at least 8 hours . . ." THAT is hog wash!

The above described factors can be researched on the internet, but the true rule of thumb is to run the pump so as to turn the pool over at LEAST twice a day. This assumes that you maintain a chlorine residual of at least 2 parts per million (which is recommended). If you have a higher chlorine residual, you still need to turn the pump over at least twice for filtering purposes. Remember filtering and disinfecting (chlorine) are not the same AND this is the reason that it is so important to know the size of your filter.

Calculate out your pool volume, the volume you need to turn over multiply by two and you have the volume you need to move. Calculate your pump capability (variable pumps need to be calculated at maximum efficient flow based on power consumption).

You should see huge improvement in your pool clarity. IF you notice that the water quality is degrading (foggy etc.) you can adjust your pump timer up to an acceptable level. Algae is a completely different problem usually related to nutrients and that is another story (i.e. PH, Phosphates, type of disinfectant, quality of disinfectant etc.).

SO have fun.
