I respectfully disagree but will not debate a few hours of difference. Pushing subjective opinions is a waste of time. That's why I like real data, which you haven't presented. :) This is my last post on the topic. Respectfully

As mentioned, prior to installing the UV I had an occasional bout with algae with my current system. The UV sanitizer is sized to kills pathogens in the water with every cycle. After installing the UV, there has been a noticable difference in water quality and clarity. Not even cloudy water...

SWG systems do not walk on water and are not perfect. Neither are UV sanitizers. It's about weighing out the pros and cons and selecting based on your individual requirements. I'm happy to hear you have had success with SWG and never had to shock. Honestly, I don't think you can say no one ever...

No worries, I'm here for fun and to learn. Currently, with respect to end results, I see very little difference between SWG and UV in terms of results. I have a close friend who runs a SWG and he shared some pros and cons with me based on his experience. At the end of our conversation we reached...

I hear you, Since installing the Eco Pump my energy costs have decreased at least 50% compared to running a pump full force 100% of the time. My current cost $200/season or $40/month for electricity. Some people still run low efficency and high cost pumps as you probably know. :) I am an...

You bring up some good points. As far a nasties in the pool, obviously a UV sterilizer will not eliminate algae that is secured to the liner and not able to pass through the sterilizer. That's why we need chlorine supplements, otherwise having a sterilizer is a waste of money. You need to...

Yes, for a SWAG or baseline I think it's great. But in reality there could be a difference. Ie. The UV sterilizer impact to head loss and other equipment that impact head loss.. I'll let you know how things work out. Most head loss and GPM curves based on pump HP show a small difference in head...

That's fine, but it doesn't hurt to know. I like data and making informed decisions. I'm curious. From my point of view, regardless of how many times you decide to turn over in one day, I am targeting one complete turn over in minimal time. (At full power) Then see how I can cut this down by...

You're spot on and I kind of got the impression there are many strong opinions here. But, as mentioned, I'm here because I like the hobby, flexible, open to learn, and share experiences. You have to have fun in your spare time. :)

Understood. I like to decompose problems into digestable parts. Flow rate is a data point that will tell me how long it takes to turn over the pool, which will help with energy usage estimates. Thanks again.

I looked into this a bit further and decided to install a flow meter that will be located down stream from my Pool Frog XL chlorinator, right before water returns to the pool. I need to obtain a measurement and understand the current flow rate returning to my pool and decide what to do from...

Pool surface is white concrete, Volume is 32,000 gallons. I don't use any other chemicals due to heater risks. Outside of Alkalinity and PH additives usually at pool opening. CYA is maintained and checked weekly with ColorQ 7 unit. Very acccurate. So far no green hair from bleach blonde swimmers :)

The UV unit is about 40" in height with two 90 degree bends at inlet and outlet. Before installing the unit the pressure was fine. Will have to play with this one. Need to study your Hydraulics 101 post. Very comprehensive and informative. Thanks

Last year I had to replace my heat exchanger due to a small leak. Although the frog puts out minimal chlorine I was unaware it puts out excessive metals. So you suggest eliminating the frog due to risks to my heater? I'm Curious.

I use marine grease that you can buy on Amazon. Is your pump above your water level? Also, last year I installed a check valve on the suction side of the pump which made a huge difference. My leak on the suction side originated from a cracked union used to connect the pipe to the pump. Try...

Sounds like fun! It's a nice hobby. See you in another discussion.

No worries. I appreciate the advice! There are many ways to achieve crystal clear water and Chlorine is a sure proven solution. I just want to minimize the amount of chlorine that goes into the pool. I avoided an ozonator because of the risks to my heat exchanger. Be well and I enjoyed the chat.

I hear you and appreciate the comment. I do use chlorine that I keep at 3ppm using the Poolfrog XL. I also liquid shock once a week. I have the heater with a Cupro nickel heat exchanger and want to avoid corrosion issues installing a SWG system. (Or excessive chlorine for that matter) With all...

Thanks, I'll reach out. This is next years project. Too much swimming left to do this year and I'm getting by for now. :)

Try JB Water weld. (See attached) You may be able to squeeze another season or two for a $7 investment. Youtube videos will tell you how to effectively apply this to fix the issue. YOu're working on the presssure side which is always a pain! Good Luck!

I installed a DEl UVC-50 this year and ended up with very high pressure. Looks like the Del has a lot of 90 degree bends and I made the mistake of installing in with a 2" to 1.5" reducer fitting. Next year I will make sure all pipes coming out of the pump are 2" right through to the filter and...

Hey Texas! You look like a happy pool owner! I'm usually a late closer. The heater starts to earn it's rent starting September and I close by mid October. You probably keep yours open almost all year in Texas! I envy you 10 month guys! Thanks for the message!

Hello Everyone I noticed this site and decided to give it a try. I have owned pools for over 20 years and interested in learning as well as sharing experiences. Looking forward to chatting with everyone on the site. I have a 35,000 gallon inground pool with a Hayward 400,000 btu milivolt heater...
