Chlorine Lock is a reasonable description, but not accurate, Chlorine becomes bound to the CYA and it's effectiveness is heavily diminished, which is why it is important to maintain FC as described in Pool School so that the Chlorine Residual does it's job effectively and quickly. Switch...

Whilst you wait for your FAS-DPD re-agents to arrive remember that DPD tests can bleach out over 10ppm FC, so it is important that when testing you rinse and leave only a few drops of pool water before adding your DPD Tablet, which should result in a pink reaction which indicates the presence of...

Small photometers tend to be cheap and inaccurate and are more costly in the long term than the real mccoys. If you seriously need to consider a photometer, you should look at Palintest in the USA or Lovibond/Palintest in Europe/Asia. These are the only two companies whom are worthy of...

^This and if the first dilution 1:1 test still reads high then goto 1:3 parts pool/tap water and so on until you get a reading which can give a more definitive range of your CYA.

Welcome to the forum, The shock process as detailed in pool school at the top right of the forum page details the process of shocking your pool, if you have a green swamp you will need to spend some time, shocking your pool is not just running the FC up high once and then letting it drop, it's...

Low CH in a liner pool is not an issue as there is nothing to erode (no plaster/grout), the water is not corrosive enough to attack metal either so increasing your CH is just an expense you dont need. Only thing I would say it gives you is the flexibility to use Calcium Hypochlorite if you see...

Here in the UK 1-3ppm for INDOOR pools with no Cyanuric Acid content is the norm, as for some countries in Europe their regulations do require ridiculously low amounts of Chlorine Residual in the ballpark you mention. A Few issues for you to consider: With Cyanuric Acid in your water, the...

I wouldn't advise maintaining a pool chemistry which promotes erosion of the plaster, I have saw many tiled/plaster pools where the grout and plaster has been eroded and it is not pleasant, some areas will loose lots of plaster whilst other areas will loose little or none, duraleigh is spot on.

The following threads: fas-dpd-kits-shipped-to-australia-t56488.html?hilit=australia tf-100-order-from-td-chlorinators-t55966.html?hilit=australia Have relevant information for you especially getting the TF100 kit to Australia.

We will certainly do our best to help out. I ran a search and cannot find the testing product you mentioned. Are they test strips? I would be wary of being able to pick up a test kit that will do what you want, without purchasing online, I know you would be unable to get the tf100 kit but may...

Welcome to the forum! We will be happy to help out! Because you are using Di-Chlor I would hazard a guess your Cyanuric Acid level is very high, therefore slowing down the efficiency of your Free Chlorine residual. Do you have the ability to test for everything else? In order to help out we...

USA Would be Palintest photometers, which give an easier reading than comparator tests, I use the word easier as they are very accurate and require calibration very rarely but have no real benefit to a domestic user unless you of are colour blind/partially sighted. Photometers are expensive...

As a rule of thumb Bleach (Sodium Hypochlorite) is best for domestic use as it is cheap, effective, has less handling issues than many other forms and readily available from a variety of suppliers including your local supermarket. It increases FC and salt only with (dependant on quality) a...

Re: how important are the "two dippers" for the chlorine tes my experience is I use a heaped spoonful of powder, and providing I get a good solid pink colour after swirling, the result is accurate.

See this post the-differences-in-pool-testing-equipment-t53470.html for the reason you should not believe any results you have received from your test strips, do yourself a favour, chuck the strips in the bin and get the tf100 kit

If your shocking I would guess its more likely to be Di-Chlor granular (Tri-Chlor is a slow dissolve tablet) but either way both contain Cyanuric Acid which will also raise your CYA level, I would slow down on raising your CYA, as it can take upto a week for the true CYA level to rear it's head...

Sorry I haven't had a chance to reply earlier, because its the Just Getting Started Section I keep answers fairly simple, inkeeping with the request of the forum with more detail if requested, sykorsky's post is spot on though and covers the answer in sufficient detail.

It's the two urban myths of swimming pools, smarting eyes are "usually" caused by ph out of range, whilst a smell of chlorine is "usually" caused by high cc's, which is usually in turn a result of low chlorine levels. High cc's will cause bather discomfort and more nasty things like pathogens...

Chlorine levels do not cause irritation, pH levels do, the eye socket and skin have a pH around 7.5 which is why we keep pH at that level so it's comfortable for bathers, the smell of chlorine at the public pool was through the production of chloramines (or combined chlorine) which is not...

Dont take any water back to the pool store, their results can be inaccurate and confusing, with advice which is expensive and ill-informed. Just use them for the odd thing that you can't buy in the superstore, get your own kit, ask advice here when required and your good ;-)

1) how are you testing your pool, we cannot answer your chlorine question until we know the answer to this important question, we need to know make, model and reagent information for your testing regime. 2/3) ill leave to better informed members on metals as I do not know Observation 1 You...

1 I would not advise testing and adjusting your TA first, it is a weekly/fortnightly check and does not change drastically enough to justify regular testing and correction, even when I am testing the water quality I always go through the following process pH FC TC then weekly TA CH then monthly...

Re: Sparkling Pool In Spite Of Zero Ph Total Alkalinity And I find it highly unlikely any of the pH values stated above are correct, pH of 1.6/2.0 would be akin to swimming in liquid that is more acidic than vinegar! Listen to what everyone is telling you here, read pool school and throw the...

Welcome to TFPool! Everything jbizzle said is a +1 from me, also you need to start shocking your pool, as Algae already has a foothold. Note this link pool-school/chlorine_cya_chart_shock which determines the correct FC levels for your CYA which in this case is Min 7ppm and a shock of 39ppm...

Voila

I'm no expert on cover supplies but I frequently read posts regarding solar covers, as they divert solar energy into the pool water and provide good heat loss retention, to maximise reduction of gas use. Given your pool is 28x14 I think you could get away without a roller, which should offer...

Hi and welcome to the site! Your available Chlorine in that brand looks to be around 4-6%, the label says 4% at use by date so it will come out of the factory slightly higher (probably 5%) and as it's Sodium Hypochlorite a number of ambient factors will dictate how fast it loses its strength...

Absolutely, you can set the timer up to have the pool warm at the times it is mostly used. Another way is to run your boiler 24/7, but utilise a pool cover to reduce gas use, depending on the type of cover your gas bill can drop substantially if you cover your pool at night etc. The only issue...

Skimmer won't function very well unless it is actively removing surface water, so installation of a collar or weir flap (whichever yours is designed for) should be a priority. Turning down the main drains throughput should allow the hoover to pass over without getting stuck, it's usually best...

As Dave says above you need to figure out how much water you need to replace in your pool to bring CYA under control if the CYA is 100 you need to replace 50% to bring it to 50ppm, if the CYA is 200 you need to replace 75% of your water and so on. In order to get an idea of CYA level I would...
