Just opened the pool - seems the app has gotten an update and is prompting me to sign up for premium, which I have had for several years. I should still have time left from last year - I have notice that it will renew on May 21 which I have OK'd. Just stumbled across the answer, I'll leave...

Very insightful. Though it was like pulling teeth, I got a recommendation from Hayward - TriStar VSP 900 1.85HP. Keypad controller on the unit, gives me all the flexibility I need. I was told that 2.7HP units would only be needed for pools >40,000 gallons. On to finding someone to install it.

Upon further review I noticed that the quote includes providing and installing a safety vacuum release unit. Is this required by updated regulations? Based on the price of such devices this would increase cost significantly, so we can leave the cost issue aside. Quote is for a Pentair...

That's a more credible review than random Amazon, I didn't know your depth of experience with installs. Do you have any thoughts on the installed quote for the Pentair?

There is no automation. Historically it has run all the time on low speed except for 4-6 hours overnight on high, except when we choose to run on high like to run the vacuum. This is controlled by a mechanical timer or manually. I figured the new pump would have a keypad on the unit and we'd...

I don't know how old the pump is, but the motor was replaced about 15 years ago so I think it logical to replace the whole pump at this time. 1.5HP 230V model SP4010X152NS. In shopping online I see mention of "drop-in replacement" options but have my doubts and expect the replacement will have...

Thank you - it is still a bit hazy/cloudy and failed (barely) the OCLT. Once we get the pH in order we'll go forward with the SLAM. The pool store did get a pH reading of 8.5 which indicates the reagent is OK. They also measured CYA at 40. To your point, our TA is 90, high end of the target...

The pH test is working the same as when FC was zero, and everything in between. I'm not aware of a "good CYA" test beyond the Taylor test kit which is what I use. I'm confident in my CYA reading of 40. Update pic attached - reflection off the water makes it harder to see, but the drains are...

Green is all gone, put in total of 8 gal 10% chlorine, the last two raised FC from 4 to 12. There was a lot of dirt in the pool, have changed the vacuum bag three times. Just cloudy now and getting clearer, can see the drains in deep end. Additional readings - TA 90, CH 240, CSI 0.61, Temp...

Pool techs put something for pH but no shock, we just put in four gallons of chlorine. Their testing showed what they put in lowered pH to 7.8 but we'll see what ours shows in a couple hours as you suggested.

Pics didn't upload...

This thread will be similar to drewghost but I didn't want to bogart his. This is the first time I can remember the pool being green at opening. Pool company will be here any moment to hook up the filter and all the other things they do. The pH is off the charts literally, I can't measure it...

Update - turns out we were unable to get the pH all the way down to 7.2 though we didn't push it. Starting on 8/3 through 8/7 we put 12 lbs of dry acid in. After 10 lbs the reading was 7.4 so last night we put in another 2 lbs but it did not drop. Here are todays results: FC 7.5 pH 7.4 TA 80...

Just did the testing - good bit of rain yesterday and about to put in a gallon of chlorine. FC 5 pH 8 TA 90 CH 325 CYA 60 CSI 0.39 Temp 82 TA and CH have been steady all year. Just to explain the interpolation - using the smaller sample option, after 8 drops the sample turns from green to...

I just found out some of the readings are days old, will retest then post. We have not used any fill water. Great tip about lowering to 7.2, only thought had been to get it back to ideal range.

Knock on wood, the only problem this season. The water has been crystal clear all year. Here are readings from yesterday (we use PoolMath to track all activity): FC 6.5 pH 8.0 TA 85 CH 325 CYA 60 CSI 0.38 Temp 84 Acid was put in 6 days ago, dropped pH to 7.6 but it bounced back up; this has...

My compliments to proavia, I found this thread after discovering cloudy water a couple days ago despite the PoolMath app values all being in range. We are guilty of lingering at the lower end of the target range, occasionally dropping below. No more - we double-dosed yesterday and very quickly...

Thanks for the suggestion but I don't think that will move the issue forward, only confirm what I've already stated. I'm going to try and contact Polaris and see what they say - I think leaking at the three swivel joints plus constant flow from the pressure release valve at the sidewall are the...

Near the end of last season the vacuum hose seemed to be breaking down so during the winter my husband got another complete hose and backup valve. He also put new belts and gears (thought about bearings) in the vacuum so it is working great. The one confusing thing is the hose leaks noticeably...

Yeah, I don't get what is happening with CYA. Going back to when the pool was opened, testing showed FC 0.2, pH 7.5, TA 40, CH 100, CYA 40. After opening we added one gallon of liquid chlorine and two 1 lb bags of Cal Hypo 57.8% which we regretted since FC jumped to 8.8 (no big loss water temp...

Despite reluctance we've used muriatic acid in attempting to lower pH. CYA is always a problem despite not using pucks (except during one weekend trip), it was 40 when the pool was opened May 3 then reached 80 by May 29 where it has remained. CH has been consistently 250, TA 80-90, FC in the...

Thanks to Leebo and Newdude - the cliff metaphor is a good one. I've been quite clear in our intent to follow the FC/CYA ratio but with a hope that phosphate removal would allow us to aim for the lower half and not use as much chlorine. The use of Orenda was beneficial (latest test shows 125...

mknauss I'm not sure how the hierarchy works here, perhaps you speak for TFPC. Are you aware of the following article on the site: https://www.troublefreepool.com/wiki/index.php?title=Phosphate_Removers I have also found posts by Leebo, Richard320, Swampwoman, and Joyfulnoise (among others) who...

Just did the phosphate removal last week. Readings were in 1500-2000 ppb range, water crystal clear. Orenda warns not to put too much of the PR-10000 in so we put in slightly less than the dosing chart indicated. It clouded up just as they said where poured in around the perimeter (pump on...

Moved from here. I hesitate to post here because it has been five years since someone did, but my topic is most closely associated with the content here. The following has happened to me twice - using my Taylor 2006 kit I follow instructions for the full amounts of reagents and get a CH reading...

JoyfulNoise, we had made the decision to use Muriatic acid when that need arises due to convincing recommendations herein. We do get fairly extensive fresh water exchanges - we typically pump out three times per winter. We've exclusively used pucks in seasons past so the CYA would be in the...

One can mention topics in an effort to discredit them, which is exactly the case with my reference to Leslies. I also mentioned that I had the pool store do testing to get confirmation on CYA since the Taylor CYA test is the most difficult one to nail down and I was concerned my reading wasn't...
