  1. How did you test salt? That seems like a drastic swing in the matter of a few days. If you're reading this off the SWG, I'd recommend getting a proper test for the salt -

  2. I'd really be surprised at that level of salt drop. I'll put it to you this way - when we had the pool installed 9 years ago, the installers put too much salt in. Was at the very top level of the SWG acceptable range (Think it was JUST over.) Took 8 or 9 years (Forget if it was this year or last) that I finally added salt. . .

  3. I'm still in shock at how many of you answer vendor calls. This is nothing to get worked up about, just send the call to VM and move on with your day.

  4. Vendors that call repeatedly (I'm looking at you Sonicwall - a call a week with a list of devices that expire really isn't necessary) get on a special list in my phone system. Forwards immediately to vm. Eventually it'll forward immediately to a service of my choosing. . .

  5. Hey Pat! Question, I am setting this up for a client. We are already using LDAP/AD for SSL VPN and now want to shift to Duo. I have Radius installed and am going through the Duo proxy config. So you point the [radius_server_auto] to the Sonicwall and not Radius server itself? If that is the case, did you have to configure the [radius_client] section at all? Trying to figure out how the setup all flows together. Thanks!

  6. For this case, we're pointing directly to the DC, so can't comment on the radius piece. ad_client points to DC, and radius_server_auto points to the Sonicwall. The client vs server is a bit confusing in that it feels backwards.

  7. Ahh, ok I see. I think this same setup will work for me as well. We are currently using LDAP/AD for SSL VPN authentication. Seems like the Radius proxy just handles the communication between AD, the Sonicwall and Duo Cloud. You did mention you had put in some details for the [cloud] section. I was looking through that primary KB article and I didn't see where it said to plug in values for that. Might be missing something obvious though. Curious what you may have stuck in for that. Thanks again!

  8. Ya rock is not fun at all. We dig about 16 inches and hit limestone. Most of Eastern Mo is a giant cave so rock removal was a long and mostly un fun process.

  9. I always say, anything is possible, it just costs more!

  10. Yes, thats correct, although I held mine a little high because we used 'pretty rock' around them. It ended up being just a sliver of 3/4 inch after a 90 from the lines. Then the

  11. Works for me, thanks. Last question - why the antifreeze, as opposed to just blowing the line out? Worried about rain water getting in through the jets, I'm assuming?

  12. There is a GUI tool available for Exchange 2019 tools that a developer made. I'm not at my computer to link it but it exists!

  13. Neat looking, I'll have to check it out. Thanks for the heads up.

  14. I would highly recommend a built in autocover if you are doing a rectangle. So many benefits from keeping the heat in, water clean, pool secure, I opened the pool this year am still had 2ppm chlorine. It just rocks.

  15. This x1000. Maintain it regularly. SO worth it, but pricey. Doesn't have to be a rectangle, either. We have the tracks in a rectangle, but the pool is an odd shape. Still works.

  16. Don't get me started. I do love my cover, but hate the local provider (I'm around Philly, PA.) No one else around here does these covers, so these guys charge a crazy amount for anything. Was getting some bad squeaking noise from the cover, so assumed it was the pulleys. Also struggling to open. Had them come out to do maintenance and replace. Charged me $500. For two guys. For 30 minutes. When I got home, it was still making the noise and running slow. I tightened up the clutch myself, noise stopped, opens fine. I didn't even think they showed up, only knew it AFTER I got the bill.

  17. Would putting the modem in bridge mode and using your own router do it?

  18. It should be in bridge mode actually. I'll have to get this double-checked. We have a Sonicwall in behind it with a static.

  19. If you have a static then it can’t be in bridge mode. Bridge mode will kill the static. Your modem might be in pseudo bridge. (DHCP and WiFi off). That would not help with security edge.

  20. Yup, you're right. Forgot about that. Thanks.

  21. If you're at 121 and want to get to say 60, dump about half.

  22. I'm a Philly guy, so here goes -

  23. One bit of advise and since this is your pool and enjoyment space it's your decision.

  24. Beat me to this advice. So many people I know have them attached and can't use them in the Winter.

  25. Are we talking the device is end of support or its out of support as in you don't have an active support contract?

  26. It's software. Vendor's support is abysmal, hasn't written a new feature in years, support cost goes up every year. Community support is way better. This is one situation where I'd almost be okay with it, except for the security updates. I'm not letting them drop support, but wanted to get some opinions.

  27. 10% is way above CPI, and they have not added 10% more value to the product. If anything, support is worse and we gave a list of our grievances, issues that were unsolved, etc.

  28. So we go way back with Automate. We own our licenses (On-prem), just pay assurance. Which seems to be going up every year now.

  29. Can't agree more all around. There's been no significant investment in Automate (Or even Manage) in the past 5-10 years short of the web interface in both products, neither of which I use. I feel they're doing that simply to get away from the fat clients eventually.

  30. Okay, finally caught one of the servers having this issue and had Wireshark loaded up. Started a ping to 8.8.8.8 constantly, and turned on Wireshark. Machine in question is a Hyper-V host, and it was the management NIC that had issues. So Hyper-V guests could talk to each other, but couldn't ping the host; same in that the host could not ping

  31. I might have this figured out... Might be an EDR agent. Stay tuned.

  32. Does the problem exist when pinging one VM from another VM on the same virtual switch of a host server?

  33. Not sure - someone else posed that same question earlier today. Next time a HV guest takes a dump I plan to test.

  34. Could be. When we had our pool installed, we had a line run in case we want to add a water feature later. In that case, should be a valve for it.

  35. I had 2500 ppb of phosphates right after I opened my pool. Basically no chlorine or CYA. pH at 8.0. Alkalinity at 110. I added CYA to 40 ppm, chlorine (liquid), and boric acid to 40 ppm. Some muriatic acid to get the pH down to 7.6. Been holding those numbers ever since with liquid chlorine every day or two, muriatic acid every 10-14 days, and two pounds of baking soda last week. That’s it. Clear blue sparky water. Air temps have hit 100 a few times this year, and the pool (24’ round above ground) has been as hot as 94 for the better part of a week. Haven’t even had to backwash other than after getting the original gunk out from the pool cover spilling into the pool. Get your chemical levels in range and the phosphates won’t matter. If there is no algae in there, it doesn’t matter much if there’s food for them.

  36. Exactly. Phosphates are a pool stores best friend. They’ll sell you all kinds of stuff to handle this.

  37. Exactly. Without knowing your CYA level, ignore any advice on this thread re how much chlorine to add. Those are all guesses.

  38. Purchased a K1515A Taylor test kit. I now see why the FAS-DPD is so highly recommended. My first SLAM attempt failed because my readings were based on an inferior test method. On day 2 of SLAM trial 2 (now with FAS-DPD) and I’m starting to see a major improvement. Will follow SLAM to completion and report back. Thank you so much for your guidance.

  39. Absolutely, glad that’s working out for you!!

  40. Relatedly, when/how would you actually use a vent spigot like this ? My setup has something similar (always closed) and I’ve never known what to do with it.

  41. I would think it’s to purge any air in the system. Except it would need to be much higher if that were truly the idea behind it.

  42. My experience with D&H has been mostly similar to yours, and what I've decided on is that I (sounds like maybe you too) are just Optimizers by nature. We think about "what's the best way to do this, what's the best answer for my customer, I'm the trusted advisor and I'm trusted to spend my customers' money the best way I can"... but most MSP's just do not give a shit. It's about what's easy, what's best for them not their customers, what's the path of least resistance. And D&H is awesome for those MSP's. Where you run into trouble is when you start going above and beyond what the very very low bar is for your customers. Most MSP's don't bother to register their warranties, they wait till something breaks, it turns the NBD repair into a week long delay, and their customers just live with it.

  43. Here is a rough outline. Upgrade to 2016 using key from M365 (2019 key is not available at this time)

  44. The prep steps for that require you to have an operational 2019 server as your last exchange server, and you then perform a series of steps to convert your environment to running ExchPS directly from the management station instead of importing the PS Session. If you want to reach that goal, you need to upgrade your on-prem environment to 2019 via 2016.

  45. No need. Algae feed on phosphates, so you'll get many that state you MUST keep them as low as possible. The correct way is to keep FC where it should be so that algae can't start, thus who cares what they feed on. Pool stores love to point out phosphate is high and sell you removers.

  46. That paper is a good read. One thing he states that is worth noting is the line "3 ppm FC with 30 ppm CYA is the same as 6 ppm FC with 60 ppm CYA is the same as 10 ppm FC with 100 ppm CYA." I take that as "it depends on the situation." In an ideal situation, I think you'd want to be on the lower end of the spectrum to have less of a FC demand to use less chemicals. But that also gets close to one pool party creating a huge algae bloom.

  47. Yup, agree all around. I like having a slightly higher CYA (I stick around 70 with a SWG) simply to keep a little more FC in reserve. Doesn't hurt me, salt cell still barely runs to keep up, but hopefully if ever needed and something goes wrong, that slightly higher CYA saves me.

  48. Actually not a lot! Trees are barring the sun most of the day. Id say it gets direct sunlight from 10am to 14h30

  49. Yeh, tough to determine. That overnight test will answer it for you.

  50. SLAM, just like the others have said. CYA is 48 (Round to 50) meaning you need to get FC to 20 and KEEP it there until you pass an overnight chlorine loss test. Don't bring it to 20 in the morning, then forget about it until bed. All day, whatever is in the pool, is chewing on that chlorine. As soon as it drops below SLAM level, you're losing the battle. Check it several times a day initial. Don't stop checking and adding until you pass the overnight chlorine loss test.

  51. So given my FC is still high (16 ppm), I need to let it drift back down again. It has remained high for a few days now. I have my pump running at night (9 hours total run time), but have now shut the SWG down…once it gets to around 3-4 ppm, I will turn it back on again and follow your advice by moving it to 50%, and see where my chlorine readings end up.

  52. Makes sense - no reason to be that high unless there's an issue, so let it drop. But. . . With a CYA of 40, your TARGET FC should be 5-7. Minimum 3. That's if using liquid chlorine. Since you're on a SWG, it's recommended to run your CYA higher. Here's an explanation from one of the experts at Trouble Free Pool, who explains it much more elegantly than I, when asked why a higher CYA for SWG -

  53. Oh, also. . . Set SWG to 0. Slowly turn it up and listen for a relay to click. That's the electronics engaging (At least my Hayward does this.) If you hear the click, that's your first good sign. Crank it to 100 (So it doesn't turn off the minute you walk away) and look at your returns. Do you see a hint of bubbles or oxygen in the water? That's the SWG doing its thing. Set back to 0 (Or turn off SWG) - do they go away?

  54. I get it, but high levels can damage the cell and cause it to fail prematurely

  55. CYA keeps most FC in reserve. So it’s inactive until needed. If you have your FC in the range that an SWG manual recommends but have your CYA at 60, you’re going to have a green pool.

  56. CYA is around 30 and pool is perfectly clear

  57. Excellent! For others that might have a high CYA, want to make sure they don’t blindly follow a manual that isn’t taking into account proper variables.

  58. Thanks I’ll look into algaecide. FC reading tops out at 15 for Leslie’s tests but I had it at about 26 ppm as per the cya chart on tfp. I’m amazed there might still be algae with how I have been shocking it. Looks been out of commission for two weeks here in central Texas and I’m ready to get the kids in again. Appreciate the suggestion.

  59. Does your testing of CYA match Leslie's? You're supposed to round up, so technically you'd be a 70 based on the Leslie's test. But 61 is pretty close to 60, so. . . If you're keeping it at 26 FC, I'd say you're at SLAM levels.
