Ok, thanks a lot! I will look into the ingredients of Glorix. I found the cyanuric acid on a webshop and they advertise it to use for pools so that's should be fine. So, the HTH dry chlorine comes with a bunch of extra ingredients, but the briquettes consist of 90+% calcium hypochlorite , so that would be a good option to go with right? (combined with the cyanuric acid)

Thanks a lot to both of you! That's a lot of helpfull information. I will do some more research on the products I can get locally. Also I will order the taylor testkit! Laundry bleach used around here is 'Glorix' but I cannot find any informatino on the ingredients. I suspect it is on the bottle so I'll hop into a big box store this weekend and make a picture of the ingredients. I did some research on the ingredients of the HTH pool products. It's hard to find but by searching for the MSDS sheet I did find some information: hth Ph minus: "The main ingredient is Sodium Bisulfate (Dry Acid) meant to reduce PH and TA" Sodium hydrogensulphate : concentration 91.5 %- 94.7 % Sodium sulphate concentration: 4.8 %- 8.0% hth PH plus: Sodium Carbonate (Soda Ash) (100%) HTH dry chlorine granular: According to this sheet: http://www.pollardwater.com/pdf/MSDS_Sheets/HTH Granular Chlorine MSDS.pdf the ingredients are: 60-80% calcium hypochlorite 10-20% sodium chloride 0-5% calcium chlorate 0-5% calcium chloride 0-4% calcium hydroxide 0-5% calcium carbonate HTH briquettes Main ingredient calcium hypochlorite (>90 %) <3% calcium dihydroxide <3% calcium chloride < 2% calcium chlorate I know for sure I can get hands on most of the HTH products over here. According to this information, any recommendations on the products to go with? I tried comparing the chemical formula of Dichloroisocyanuric acid with some of the products above but it's quite complicated for me.. PS If I look on webshops selling HTH products they all say 'This is an anorganic chlorine solution and contains no stabilizer (cynatic acid)'. And also, they say 'using stabilized chlorine' can cause overstabilisation and because of that green water and so they recommend non-stabilized chlorine'. I can get cyanic acid so it's no problem to add stabilizer seperate from a chlorine solutions, however why do all the stores evangelize against this? Thanks a lot again guys. I am a total newby and this forum and your anwers really helps me boost my knowledge!

Hi, I have one more question. Reading through the dichlor method I basically need to get 2 products: dichlor and Clorox 6% Unscented bleach. However, these product are both very american. I cannot find anything like this in The Netherlands. Does anyone know what to use and where to get it in The Netherlands? I can get hth products as it seems which are also selled in the US, however they have chloor sanitizers but I don't know if I can use that because it isn't named dichloor? http://www.hthpools.com/spa/spa-products/sanitize I also can get 'interline' products: http://www.interline-products.com/8726.htm they have chlorine tablets, chlorine granulate, etc. But I don't know if it's dichloor..

Thanks a lot! This really helps. Indeed my bias with chlorine came from exactly what you described. I will switch to the dichlor/bleach method as of my next water renewal. I am located in The Netherlands btw, and around here they advertise a lot with all kind of miracle liquids which are supposed to be revolutinairy for water treatment. SWT, AquaFinesse and SpaBalancer are the main brands around here. I am stuck with 3 more questions, hope you can help me out on this: - Calcium level is important is what I learned. But how can I correct the calcium? Would you recommend something like this? https://www.amazon.com/HotSpring-Vanishing-Calcium-Remover-76029/dp/B004GFQRLG (I already use a prefill filter since a couple of months which also filters out calcium so I'd expect that the calcium levels are OK) - As for the testkit, which kit is recommended? I read good things about the Taylor testkit. I already have a very accurate digital PH meter, so I don't need any testing stuff for that. Would this kit be recommended to go with? http://www.ebay.com/itm/Taylor-K-2006-Complete-FAS-DPD-Chlorine-Swimming-Pool-Water-Test-Kit-K2006/121728488819 or would this kit suffice too: https://www.taylortechnologies.com/nl/product/test-kits/surecheck-total-balance-alkalinitybromine-chlorine-hi-range-dpdcyahardnessph--K-1005?pageid=19 - I have read that the liquid PH minus that pool stores around here sell are no good for equipment. So I have found a non-liquid solution which is based on natrium bisulfate. Is that good too? Or should I really go get Muriatic Acid.

Thanks for the reply! I have a PH meter and test strips for TA and chlorine. The test strips are a bit hard to read so I am thinking of ordering a Taylor testkit since I have read about it on this forum. The PH keeps drifting up at the moment, I think it is because the TA is too high, but I can't pinpoint a number on the TA because it's just color indication that says it's high. I can't get the TA down using PH minus appearantly (I tried). However, I have read a topic on this forum about bringing TA down so I will try that out. As for the Dichlor/bleach method: is this method better then for example SWT or SpaBalancer? I started this topic mainly because I am going to renew my water next week and I want to switch to a different spa maintenance method. Maybe I will use Dichlor method then. One more question: I have read that PH minus that some stores sell is not too good for the equipment, is that true? The most shops here (Netherlands) sell PH minus in liquid form, it is unknown to me what chemicals are used in it. I also found a PH minus granulate based on natrium bisulfate. Is it true that this is bad for the materials of the spa and that I'm better of using Muriatic Acid? I can buy Muriatic Acid here but the advertised application is always like for removing calcium or cement. Also, it comes with different names and concentrations for example 10%, 30% . Is Muriatic Acid really the best solution and why do no pool shops sell this but all sell other chemicals, if the other chemicals are worse for equipment? Thanks :)!

Hi All, First off, I'm new on this forum. Please let me know if my topic belongs elsewhere. I own a spa for like 1,5 year now and I'm looking for the best way to treat my water. At the moment I use Guardian SWT. This is quite effective, but I'm afraid that it is bad for my spa parts. My spa broke 2 times already and both times it seemed like something was eating the material. They told me this could be due to high doses chlorine, but SWT is chlorine free. So it must be either SWT or maybe the hardness of my water (it's quite hard around here). Since my last water renewal I use a prefill filter which filters out the calcium I think, it makes the water softer. However, I'm considering to use something else then SWT. The reason I chose SWT at first is because it's chlorine free, and with that it does not smell or irritate to eyes which are common side effects of chlorine I think? So looking at chlorine-free alternatives I have found SpaBalancer (Lotus Fresh) which seems to be something like Guardian SWT, but it is very hard for me to tell the differences and the different effect it will have on my water treatment or spa materials. Another famous one (around here anyways) is AquaFinesse which is commonly used in addition to chlorine. Can someone advise or share experience on the water treatment? (especially the effect on the spa materials). I don't know what treatment I should use next. Altough I prefer a non-chlorine treatment, if a chlorine treatment comes out as the best option for both my water quality and spa materials then I have no problem switching to chlorine treatment. However, maybe SpaBalancer is the magic answer to my problems. It is hard to find reviews on specific treatments, especially from spa owners who have used a certain treatment for multiple years. Hope to gain some knowledge here! Thanks a lot in advance!
