return jet

[sun and water]

Which direction should the return jet point?

[aylad]

Generally in a direction that helps push debris toward the skimmer. If you have an area of the pool floor that doesn't get good circulation, you can point it there. If you are trying to raise your pH or lower your TA, then it needs to be pointed toward the water surface so that it creates ripples. Just depends on what you need!

Ok thank you! I didn't realize it could raise pH or lower TA.

[aylad]

Aeration of the water basically allows the CO2 in the water to outgas, causing the water to lose some of its acidity, therefore raising the pH. Splashing kids, fountains, returns rippling the surface, they all have that same effect.

Directing the returns upward is part of the process for lowering alk. If you want the whole process, log out of the forum, go to the forum home page under the section called "dealing with alkalinity and calcium" and then read the sticky there about alkalinity How-to and FAQ.

If I have a lot of floating debris, then I aim my jet upward and towards the side to create slight rippling on the surface and to create a circular waterflow to direct the debris to the skimmer. (I have a round pool.) When I add bleach (through my skimmer), i aim the jet downwards to circulate and mix the bleach in well.
