  1. Do not put that in the pool .
  2. Assuming your pool is 130 cubic meters then you need to add the following chemicals To raise the alkalinity you need to add sodium bicarbonate NaHCO3 25 kg approx To raise the pH you need to add sodium carbonate Na2CO3 (Soda ash) 15 kg approx In your case you really should get the total alkalinity sorted first, get to around 120ppm DO NOT ADD THE CHEMICALS ALL IN ONE GO MAKE SURE THE PUMP IS RUNNING 24/7 ENSURING THE FILTER IS CLEAN ADD THE sodium bicarbonate NaHCO3 FIRST. the best way to do this is little at a time........ Day 1 morning add 2.5 kg dissolved in water sprinkle evenly around pool Evening the same add 2.5 kg test the water. Then backwash the filter as some of the fines may clog the filter up depending coefficient the filter is. Day 2 as above until you reach the desired effect doing the same every day. Once you have got the desired readings with the t/a Then you can proceed to adjust the pH using the same method . This may to some may appear little long winded but it is the best way to achieve the end result . My previous recommendation still stands dump some of your pool water as the chlorine levels are high.( YOU COULD DO THIS CHEMICALLY BUT IT IS NOT FOR A NOVICE TO DO). The old proverb is probably a good one in this case ,The solution to pollution is dilution. Any problems pm me and I will do my best to help.
  3. Make sure that when researching make sure the info you read is reasonably up to date, a great deal of stuff on the net regarding pools is getting fairly dated most of it comes from the 80s Guidelines for chemical levels really do change the 7.4... 7.8 is based on old research mainly done in the 70s . Later reasearch dictates that we lower the pH to make the hypochlorus acid far more effective.7.2--7.4 is now the norm. if you read pages 13 ,14,15 of the publication listed below will give some better understanding. The recommendations are the latest offering from PWTAG . This a UK based organization who's recommendations on design are recognized throughout the world, perhaps withe the exception of the USA, lovibond_handbook_gb.pdf The WHO a good organization seem to sit on the fence as they always do recommend pH to be kept between 7.2--- 7.8. http://www.who.int/water_sanitation_health/bathing/srwe2full.pdf Page 95 5;10;3
  4. Not enough chlorine Soda ash raises your pH and chlorine shock will extra chlorine , I would also suggest at some stage to lowering the pH to 7.2 I would suggest your chlorinator is not wok or the plates are clogged up A useful tool https://www.totalpool.co.uk/index.php/resources/dosing-calculator https://swimmingpoolchemicals.co.uk/dosecalc.php This looks like a useful design tool I have not played around with it yet, used to do all my calculations the hard way, will play about with it in the week . and post later https://draftsman.files.wordpress.com/2013/11/main-pool-lanai-new.xls

  6. This the type you could use. http://www.vikingjohnson.com/en/category/maxifit-wide-tolerance
  7. 110 Pump fittings. Generally 110mm fittings are made for the european market exc UK. Some pump manufacturers supply 2 types of fitting 110 and 4 inch with each pump, you throw away what you don't use. Some pump manufacturers supply just 1 fitting it may be stamped 110 mm but it may have been machined to accept 4 inch pipe Failing that get the socket part machined out to take 4 inch pipe. global house and other commercial pipe stores do sell a mechanical connector suitable for joining pipes of different diameters.
  8. The pump should be replaced as a matter of urgency, as you can't vac the algae settled on the bottom of the pool, Do not waste any more test strips until you have had the pool vaced and the circulation run for 24 hours at least as the results will be meaningless.. How long do the pumps run for normally, As the pool is out of commission it might be worth draining some water out say 20 percent and filling it with fresh water.
  9. OK. Before I advise any further can you take a sample half bottled water half pool water take a test accurately measured please,. Post the results with a photo if poss No need to do any calculations just the results as you test. not to worry about pH. Do you have a tds meter.? At the moment you need to get the two basic components right ,chlorine and Ph as they have safety implications. The alkalinity can be tackled next, this is important to keep your pH stable and to prevent the water to become less corrosive to the pool structure fittings etc more on that later What type of chlorine are you using photo of lables if poss The forum sponsors do a full water testing service if you send them a sample. Is your pool clear now?
  10. Buy new unless you are extremely lucky to find a well cared for one. If they are well looked after they should last for years, if not beware,I used to sell Dolphin cleaners in the uk and you should see the abuse these things are put through and people expected to have the warranties honored.,especially at the time when robot wars was on the TV!!!
  11. It is always sad when a business fails for whatever the reason.
  12. My interpretation of the readings is cynuric around 100 ppm T/A low pH 6.2 Fee chlorine very high 20 ppm total chlorine hardness high The big problem you have is that the chlorine levels are so high the test strips are suffering bleaching so really make the results meaning less apart from the pH and even that can be affected. I would suggest you do a dilution test as previously described to you until you get a mid range chorine read then multiply the answer by the correct factor. For chlorine and all other ppm readings will not work forpH Take a 50ml sample of pool water to this add 50 ml of distilled water (as we are not into life threatening science here bottled water will suffice) mix the two together then cary out your test multiply the answer x 2 that should give you a result. If you still cannot get a reading carry out the following Take a 20ml sample of pool water to this add 80 ml of distilled water (as we are not into life threatening science here bottled water will suffice) mix the two together then cary out your test multiply the answer x 5 that should give you a result. If you still cannot get a reading carry out the following Take a 10ml sample of pool water to this add 90 ml of distilled water (as we are not into life threatening science here bottled water will suffice) mix the two together then cary out your test multiply the answer x 10 that should give you a result. Makers name and expiry date of strips please.
  13. Crossey is indeed correct you are holding the strip upside down, cynuric acid is next to the the bit you hold with your fingers
  14. If you have not purchased yet ,give a two part epoxy paint careful consideration.an excellent product and should last for many years. Forum sponser carries this I believe.
