    Using a 2-speed pump on low, with sand filter (Zeosand)

    Hi. We would like to cut our electric bill down by going to a 2-speed pump, running on low, except to clean and backwash. We have a 150# Sand Dollar (SD40) with zeosand. Crown Pools said we can't use a 2-speed, because the LOW setting will not provide enough pressure to push the contaminants into the sand filter (or something along those lines). Is this true? I don't know how to create a SIG line, but our pool info is as follows:

    16x32 Doughboy buried 3' with 7' deep end
    1 skimmer, 1 return inlet
    25 mil print liner
    Pentair Dynamo 1hp, 115v
    150# SD40 sand filter
    New BBB'er and loving it!

    A second question: We need better circulation. Since we only have one return inlet, we are trying to decide whether to have a 2nd return inlet installed, or try to use THE CIRCULATOR for better circulation. Which would be a better solution to better circulation? The Circulator is cheaper and easier

    Any advice on these two issues would be greatly appreciated!



    Any advice

    From the experience from many on this board, sand filters usually filter better at lower flow rates. High flow rates tend to push the dirt through the sand while lower flow rates allow the sand to trap the dirt. I would not expect Zeosand to be much different than regular sand although better at cleaning so it should work fine at lower flow rates.

    Thanks Mark. I'll be ordering the 2-speed Pentair next week. Considering it is only around $200, and will cut our electric usage for the pump in half each month, it will pay for itself quickly!

    Thanks so much for responding.

    I do this very thing with my 2 speed pump and ZeoBrite media.

    Works just fine,

    Re: Using a 2-speed pump on low, with sand filter (Zeosand)

    Thanks HDTV! We've also ordered The Circulator to plug into our return jet - our circulation isn't the best with just one jet. So I'll be experimenting to see how the 2-speed will work with The Circulator too. We are scheduled to have a 2nd inlet installed. But as usual, the pool guy didn't show, didn't call. I'll take this as a sign to move forward with the new pump and The Circulator!

    Do you run your pump 24/7? According to one response, we would need to run ours twice as long, with the new low speed. But I intend to run it 24/7 anyway - given that it will only cost us $36/mo, as opposed to the $150 (to run it 24/7) with the current pump!

    Appreciate the help. NOW, I'm off to get my guideline ready to take on the mustard algae that has been plagueing me since 4 weeks after we filled our pool!!

    Hope you have a great weekend!

    The Circulator (Item #CIRC3)
    The Circulator is a major breakthrough which redefines pool water care. Cloudy pool water and algae can be the result of poor circulation in your pool. The patented Circulator disburses chemicals up to 1500% more fluently, greatly enhancing the purity of your pool water. This extreme circulating action helps to keep chemicals working at their maximum potential so that you can virtually eliminate cloudy pool water and algae.

    In addition to the more efficient distribution of chemicals, this powerful circulation promotes even distribution of heat - faster heating and less evaporation means money savings to you. The Circulator makes pool maintenance a breeze, resulting in time savings and more enjoyable pool. The Circulator helps protect your pool finish from etching and staining caused by harsh chemicals and debris lying dormant.

    The Circulator is a modern marvel that will give you up to 1500% more circulating power, saving you time and money and prolonging the healthy life of your pool.

    This is where I found it about a month ago, thought about trying it and instead just got a better filter and pump.

    Re: Using a 2-speed pump on low, with sand filter (Zeosand)

    I run my 2 speed on low all the time except for sweeping and backwashing.

    Circulation has been an issue for me also (even on high), but a right-angle pipe fitting in the return or better yet a poolskim or pooldevil really helps.

    Re: Using a 2-speed pump on low, with sand filter (Zeosand)

    Thanks Klight. It eases my stress on this decision more each time I hear from someone who is already doing what I think we need to do! Currently, it's supposed to take our 12 amp, 1hp motor about 10 hours to run the water through once. I read somewhere last night to expect it to take twice as long, running it on slow - which makes sense. It's no problem though, given that I want to run it 24/7 regardless. I always worry about only running it a couple of hours after I pour my bleach in at night and sweep the sides down. I'd just feel better knowing it's running all the time.

    I've ordered The Circulator (comes with a free foundtain too) and should receive it by about Tuesday, 7/29. I'll try it out for a week and come back and post the results.

    The right-angle return would be a good idea, except that, to use our automatic cleaner (which I would eventually LOVE to start using) requires that we have the inlet pointing down into the deep end. We've been having to unscrew it and adjust it each time we use the automatic, which is a pain. And NOW, it won't even climb up the sidewalls. So it's easier for me to manually vac. Unfortunately, we only have one skimmer and one return. We were scheduled to have another return installed last week, but the guy didn't show/call. So we're tyring the route of The Circulator first. I'll post results when I have them.

    We're also battling the remnants of mustard algae - it wore me out from not treating it correctly (didn't know about this site at the time) So hopefully, the The Circulator will be a big help in that too.

    But my goal is to have the pump run 24/7, The Circulator do its job, me do the hard part...add bleach every night ... and US SWIM IN OUR POOL ALL THE TIME!!

    Thanks for all the help, everyone!

    Re: Using a 2-speed pump on low, with sand filter (Zeosand)

    Hello again! I just wanted to report back about our experience with The Circulator. He charged us entirely too much for S&H. Received something that didn't look anything like the picture. It wouldn't work with our pool. We paid to return it to him so he could replace it with "the newer one". Little did we know that he charged our card again to send out "the newer one". So now, we've paid for THREE S&H. Still didn't work for our pool, so he was going to ship us some other gadget to make it work and it would end up sticking out about 6-8" into the pool! Yeh, that sounded dandy! We told him thanks, but no thanks and said we'd be returning it for a refund. I don't expect to see a refund and am VERY thankful we used a credit card instead of our debit card!! So in all, we lost the original $70 and three more S&H for about $18. He made a nice enough profit, I suppose! I WOULD NOT RECOMMEND THAT SITE OR THE PRODUCT.

    It does not appear to me it would be particularly effective on any pool.

    Even distribution of your return pool water is pretty easily managed simply by rotating eyeball fittings.

    msray, The Circulator is a gadget that simply screws into your existing return inlet and it pulsates as it spins around slowly. Because of the pulsating, it supposedly circulates the deeper water better and mixes all the water more effectively, thus, cutting down on the time you would need to run your pump. These are the claims. I've only seen one other person on this site who actually has used one for a couple of years now and loves it.

    In our case, we purchased one, AFTER Wes Weldon, The Circulator guy, assured us that it works with ANY pool! What we got was an unattractive thing that was shaped like The Circulator, but basically made of PVC, and made very cheaply - as if a machine shop was whipping them out. When we tried to put it in our eyeball, it wouldn't fit. He sent us a "newer one", which still was not workable. He then offered to send us some attachment to make it workable - and after all this, the original extra ONE INCH that it was supposed to stick out into the pool turned into SIX INCHES, assuming that his attachment would make it "workable". After paying for 3 S&H charges, we told him we didn't want anything else (especially since he kept charging our card each time he'd ship us something!)

    I've done all the research I can and was not able to find any site where you could get users' pro's and con's on it, other than askalanaquestion.com And his site is biased in favor of it. We just thought we'd take a chance on it - sounded like a good idea at the time.

    But Dave is right, direct your eyeball fitting (assuming you have only one). With your pool being a round also, you should be able to get good circulation by simply turning your eyeball or getting one of the pvc attachments that sticks out a little, but shoots the water off to the right with a pretty strong push.

    Hope all works out well for you. We ended up putting a second return in in our shallow end and we're tickled pink at how well our pool is doing now!

    Thanks Cherie ...

    I was also under the impression they were supposed to work for any pool ... and the web page does make it sound like something that would be worth having.

    Sorry for what you went through ... that is terrible
