I thought you are suppose to run your pumps when it is during the hottest part of the day???

If I would keep the pump, then can I simply run the pump /filter less time than I would with a 1 HP. Say 3 hours versus 6-7 hours.
Thanks again.

2) mas985 – Thanks for your response to my thread starting questions, I have a 1 foot raised spa with spillover so probably the builder was by installing small nozzles, trying to ensure water diverted to spa, and thus spillover. I’ll try fully removing the “nozzles” one at a time to watch what happens to spa spillover. Also thanks for your thoughts on pump economics.
3) Poconos, agree, centrifugal pump, dead head pump and very low current draw. Same pump curves for big electric submergible centrifugal pumps we install in oil wells, however for those pumps there is a sweet spot range that the pump is designed for, too low a rate and yes low power but pump in downthrust (ie wrecks bearings), two high a rate vs design range and pump in upthrust, same problem. Problem is that what I want is high volume per $, or rather high volume per amp. So I assume this is when rate is highest (haven’t looked at pump curves)?
4) CarlD – My pool is ~26,000 USGallons, is your Hayward Super Pump a two speed pump or do you just run it full at 1 HP?
5) Slowtan - I read somwhere, I think www.poolsolutions.com tip that better in my case (saltwater pool) to generate Chlorine in evening as thus longer for it to do it's work before sun burns it off again next day . . .
Reason away is it's been garden planting season around here in South Texas, especially as it’s been unusually cool, pool dropped from 72 F two weeks ago to 61 F . . . . back to heating the spa ! !

My super pump is 2 speed and I run it at low 95-99% of the time--with solar panels. But my pump is close to the pool, and the panels are the deck around the pool (nice! The deck stays cool to walk on !)
I don't know all the math but I suspect a 2.5hp pump is too darn big for most pools--but the spas may need it.
With 26k, you can go with a 1.5 superpump 2 speed and STILL get great performance in low speed.

Yeah, down in this part of the world, we don't have such a thing. Ah well. Even if that were possible, I'd still want to circulate during the hottest part of the day to keep the Cl levels constant throughout the pool, especially since I have a SWC.Originally Posted by kaybinster

Always thought you wanted to chlorinate after the sun went down to minimize the sun burning it off. I have done this now for 8 years and have never even once had a problem with any algea or any other water problems.Originally Posted by mwsmith2

Michael is talking about circulation when the water is most at risk, and, with an SWG, all is different.
Adding chlorine after the sun sets allows the chlorine to fight the algae without risk of it being broken down too soon by UV light.
As for your pool, sounds like it ain't broke--so you have no reason to fix it.

Well, if you use CYA, there's really no worry about having the sun burn it off. I agree with Carl, if it works for you, no need to change!Originally Posted by kaybinster
