My Ultra UV cost $2200 from the pool builder and that was 3 years ago. Just the parts alone for a UV 2-bulb replacement will cost you $250. Also some units are unreliable, with tank leaks when just out of 2 year warranty. That's a $500 part, plus labor to change all the parts over. Forget UV. Expensive and unreliable. My pool maintainer recommends "Pool Rx." $50 once a year or so and you can maintain a FC level of .5 to 1, if you are chlorine sensitive .
20K gallon above ground pool I'm wanting to switch to H2O2 instead of chlorine. We have solar heat with small hose size (not commercial solar panels) so that does slow the rate of flow down to the point I can't auto vac with the solar being used. Also a heat pump when necessary but idk if that affects flow rate. Multi hp pump (need the high power for auto vac, but use low when possible). Any suggestions as UV is suggested to go along with and lower H2O2 consumption? We are not chlorine sensitive, just looking for better health options.
So I can add this UV system to a saltwater system?
Replacement bulbs are an EXPENSIVE deal. For someone who runs a pool service and likes UV system so much you don't know much about the cost of maintaining them. You cost numbers are way low.
I don’t think I gave a specific price did I? It’s been about 2 years since I posted this but they still aren’t super pricey for the bulbs in comparison to what they save you in chlorine- sorta pay for themselves.
We started this on your FB post - I am adding the Lifegard Aquatics 55W UV... On shocking (also watched your pool chemicals video), you commented on FB just to watch the levels and maybe shock monthly. This is a private pool and sensitive skin comes into play, so we hope to stay between .5 and 1 FC. So total chlorine minus FC - what number do you look for as the indicator to shock? And what's worse - a higher or lower number? (Still new to this and learning lots). When shocking with liquid bleach (makes the most sense to me), what level do you shoot for? Pool Math app says to go for 10FC.
Great questions- So you would take your Total Chlorine - Free chlorine = Combined Chlorine. Your combined chlorine is what you are looking for when determining whether or not to shock the water. I like to shock when combined chlorine is around .2 - .4 (don’t let it get much higher than that) Remember, we always want combined chlorine to be 0 (which means we want total chlorine and free chlorine to be the same number i.e. (TC) 3 - (FC) 3 = 0 (CC) !!! If you run you free chlorine at 1ppm then yes, you would shock 10X that number to be 10ppm and liquid is perfectly fine to use (my preference actually).
I have a 20x40 in ground vinyl pool with a 1HP Hayward pump with an in-line chlorinator feeder. I need a flowrate of anywhere 65-80 gallons per the 12 hours I researched a few systems and some are off-line and some are on-line. Can you advise on a in-line system that would be a good fit for my pool. Hardwiring should be available, as I dont want to plug in to any 110 outlet.
For that specific flow rate look at the Bioshield by Pentair. The larger models would be perfect
I am in the process of building our first pool. I am building gunite, a 12,500gallon pool in Texas. Was looking to minimize chlorine levels as much as possible, that's what has me interested. Not worried about convenience, more worried about introducing as minimal chemicals as possible but being cost-conscious. Thoughts?
It’s a huge help for that purpose. I’d strongly recommend going that route. Now, in Texas with the low FAC level you will still battle the sun so that fine balance with cya is still necessary to some extent
@@rigbyspoolservices thanks so much. I meant to ask which you preferred for a new build: uv, ozone, or aop? Is it worth going aop combo of the 2 (cost wise to benefit), or is it going to be the best bang for the buck to add 1 (uv or ozone) to standard chlorine pool? Hope that makes some sense
@@marketsmove I really like the combo of Salt/UV together. If sticking with traditional chlorine I’d say AOP
@@rigbyspoolservices Awesome, thanks! I am very early in my build, so open to suggestions if you have other suggestions. Just looking to reduce chemicals as much as possible while being cost-conscious.
What’s the recommended cya acid level for UV pools??
That depends how high you want to run your chlorine and this is a tricky one with UV pools. The idea is to run the chlorine low around 1 or 2. But a free chlorine of 1/2 with cya at 50ppm is not enough. If your cya is at 50ppm you’d need at least 4ppm of free chlorine to keep the sanitizer level effective. Due to this, if you can get away with as little cya as possible- I’d do that. Start at 10 and see how that does, then 20.. id like max it around 30ppm, just my opinion.
Check out my video on cya if my comment above doesn’t make any sense.
@@rigbyspoolservices thanks! It’s at 100ppm right now and building up algae. Threw in a pool rx with some chlorine and algae still wants to grow. Slowly dumping and adding water to drop cya. Pool company left it at 140ppm cya and now with heat it’s getting bad
@@nando_2jz236 wow that’s crazy high. At that level you’d need about 12ppm of free chlorine to keep algae away!!! Keep lowering it and reach out if you need any help
Very informative
Thank you Tony
you get the explanation wrong
uv is a high energy intense light somewhere between xrays and visable spectrum , and it simply cooks things up in contact
what i am interested is do you put the sanitizer befor or after the media filter/pump
how much chlorine and other chemicals are still needed to agregate and catch in the filter all the stuff that is in the water that isn't neceserly biological (oxides, calcium amonia and other filth that people left behind)
I always put it after the filter, but before the chlorination system.
