    Considering if Switching to SWG for a Maryland pool season worth it.

    Well I fall outside the Newdude's list :) i have an AGP (7k gal), a 4 to 5 month season and a seriously over sized RJ45 SWCG .... i'm also lazy and hate the daily dumping of chlorine and love to go away for periods of time ..... The SWCG is a life saver and i would not be without it ..... I've...

    Does anyone have experience fresh water ionised pool system?

    Probably one of the best reads that as a commercial pool advisory from a government department that supports CYA up to 50ppm and largely agrees with TFP -> https://www.health.nsw.gov.au/environment/Publications/swimming-pool-and-spa-advisory-doc.pdf This clearly states that Chlorine is the only...

    Ahhh... the CYA test is driving me nuts

    quite honesty those should be taken with a grain of salt, a few people have proved the actual volume is less my own 12x24x52 is spiced at 32k [email protected]% but is around 26/27k litres measured and those numbers work for chemicals. I’ll bet you are closer to 13k gallons at a real working water...

    Is it required to use all CPVC after pool heater? What about polyethylene pipe underground?

    It has been recognised that residual chlorine can impact the service life of PE pipes but with service life measured around the 100yr mark it may be slightly moot point generally. Researching this i found this pdf to read...

    New here as well, wish I got here a lot sooner

    Welcome from Canberra, There are a few Adelaide members now Looks like your well and truly on the right track with your CCL test kit, when you have a chance can you post a full set of test results, round your CYA up to the next 0 value ie 43 -> 50 TRUST your CCL kit results. You haven't passed...

    New Intex 32x16x52 build with deck (lots of pictures)

    Consider the stock intex/bestway pumps max out somewhere around 10psi from memory the risk of the non schedule 40 pipe bends bursting is likely zero :)

    Stand pipe to multiport valve

    Typically there will be an o-ring there to provide the sealing. not sure for your exact model where it's situated but i have found it listed on multiple different parts diagrams for other MPV units

    Keep adding chemicals?

    I'm going to call @Costas > DownUnder to see if he can provide some more advice being local to Adelaide. If you use the poolmath application then let your CSI be a guide but don't let it rule :) if your 3x larger pool behaves similar to my AGP over winter with a cover you will go weeks doing...

    Keep adding chemicals?

    Ok a few things pop out for consideration - Adelaide (ADL) still gets decent to higher temps through March so you still have 4 to 6 weeks of potential swim time - ADL doesn't get cold enough to close pools like in the US, coldest mean min is 7.5c (45f) unless your up in the hills i guess -...

    Too much salt

    I'm with Joyfullnoise, you just need to ensure all the water is mixed fully. The drop salt test itself is no better than +-200ppm (ie one drop) and if your not using a magnetic stirrer could be worse purely due to the manual agitation of the test sample. run a few tests including one with water...

    Falling PH in vinyl AGP with swcg

    Jim, absolutely zero chemicals .... just the aforementioned fresh rain water. The dilution volume has been enough to,explain most of the drop considering I’m doing the 10ml sample test and I’ll be raising the TA today. i am surprised a little that the PH basically fell to the lower end of the...

    Falling PH in vinyl AGP with swcg

    Test overview from today CC is 0 The solar cover on and has been for about 14 days now as the weather has been variable and not really conducive to having a swim. The SWCG was off for about 5 days and has been back on for the last 4 @ 10% for 6 hours seems to be holding FC at the upper end of...

    Small sink spots after 1 year

    ANTS !!!! would be my guess.... when i first levelled the area for my AGP and had a few similar looking holes appear in the hard clay that had been at least 12-18" under the topsoil .... it wasn't till i seen the actual ants that it clicked .... under a liner they can't build up the mound around...

    Adjusting the pool chemistry

    It's generally known by the hydrocloric acid name in Australia, the label says it's 32%. For anyone in Oz within range of a Bunnings store they can pick this up under the Bondall Hydrochloric acid label.

    Adjusting the pool chemistry

    I fully agree with Tim, ignore it or just bump the upper range number to 100 in poolmath, it will lower itself over time as you add acid to counter the ph rise from the swcg usage

    Adjusting the pool chemistry

    :) as i said maybe just being grumpy today :) so a couple grains of salt ....... your largely dealing with a chemistry issue which fits under the testing and balancing section. It's quite normal for multiple things to be discussed over a period of a week or two in the one thread as it keeps all...

    Adjusting the pool chemistry

    Guess i got out of the bed on the wrong side...... The forum asks for signatures to be filled out so we don't ask this over and over .... the sig block clearly says SWG 24g/h, I wish all your posts were together so we retained the overall view of whats happening to better help out. I assume...

    Tracking CC does not show on the Overview of PoolMath

    I'm going to call it a bug or missing feature. It shows it in the log which gives you view over time. Why it doesn't show on the overview page seems like a oversight Marty is right that it is normally of no consequence but that is no reason it shouldn't be on the overview page so that at a...

    Adjusting the pool chemistry

    oops sorry missed this yesterday, even with the pool setup being in litres it is possible for the "effects of adding" section to still be in gallons, caught me out early on which is why i'm attune to any value that seems to be around 4x the expectation from the old poolmath page using a pool...

    Place pool on blanket of Artificial grass?

    I just would not bother with the pool blanket over the artificial grass i did exactly 1,2,3.....see the photos Above Ground Pool for 2 though I used proper weed matting the only comment is that the artificial grass can get hot in full sun but I’d do it again

    Adjusting the pool chemistry

    Take the dry acid back and pick up a 5l container of bondall hydrocloric acid from the building section, they usually have it outside with the bulk timber or 5l of the Bondall pool acid in the pool section if they have it ...... identical stuff just different labels, they call it muriatic acid...

    Adjusting the pool chemistry

    STOP...... looks like you still have poolmath set to gallons.... based one your proposed quantities.... check You are using liters not gallons 1.5kg of dry cya will raise it to 50ppm in your 30k litre pool

    Alkalinity measures difference

    Hopefully the chem gurus will pop up soon but those results are concerning. Can you detail you pool in your signature please. I'm going to assume you are using a SWCG as your primary chlorination source though. 1. the salt level may look high to the US members but it is likely ok depending on...

    Alkalinity measures difference

    I assume you mean it turns red when you put in the detection reagent in step 4, What are all the other results? maybe they might give us a clue... Edit PS, i'll believe the CCL kit as long as we don't pick up a testing error :) From the Instructions...... 1. Rinse the total alkalinity viewing...

    24 Hour SWG Output for PoolMath

    Depending on how you have the units set in poolmath 24g/h = 576 grams per day or 1.27 lbs per day

    Pool Pump Concerns

    That myth has well and truly been busted...... filtration and circulation are needed for some reasons but NOT for the prevention of Algae. Sanitation (Chlorine) does that. Ultimately that will be season dependent, deep in the middle of winter in non tropical areas it likely doesn't have any...
