AquaLife Posted October 26, 2010 Report Share Posted October 26, 2010 How many of you guys use anti chlorine? I filled my goldfish pond up direct with tap water, at times 80% on water changes, without any issue. I wonder if it's alright with tropical.

alanmin4304 Posted October 26, 2010 Report Share Posted October 26, 2010 Copied from a previous post: When you add chlorine to water you get hypochlorous acid which reacts with the amines (in all proteins) and forms monochloramine. When you add more chlorine you get dichloramine and even more you get trichloramine. All these (and other reactions) form part of the "chlorine demand" in the water. You cannot get free available chlorine until this "chlorine demand" is satisfied. Therefore when the reaction is pushed towards trichloramine there will be virtually no monochloramine present. In the US they treat the water with monochloramie (made by reacting chlorine with ammonia) because chlorine will react with other impurities in the water and form some compounds that are not so nice (such as acetone) where as monochloramine will not. Monochloramine is not as effective in treating water as chlorine as is used in NZ but is still a strong oxidising agent. When people complain that the chlorine in a swimming pool is too strong and it is burning their eyes the problem usually is that the free available chlorine has been used up by contaminants in the water (such as urea) and this has pushed the chloramines back towards the monochloramine and this is what is burning their eyes. The problem is fixed by adding more chlorine. When you allow water to stand or aerate it to get rid of the chlorine the chloramines all move back to monochloramine and this will react with your fish the same as an under chlorinated swimming pool will with your eyes. Chlorine and all chloramines can be converted to more harmless chemicals with the addition of sodium thiosulphate. Flourine is not added to drinking water, flouride is sometimes. Drinking water will contain various impurites that add to the chlorine demand and will form chloramines Quote Link to comment Share on other sites More sharing options...
supasi Posted October 28, 2010 Report Share Posted October 28, 2010 So, basically Alan, That means that when the water in your local swimming pool is hurting your eyes it means its because someone is pissing in the water??? I knew there was a reason I dont swim in pools. :lol: Quote Link to comment Share on other sites More sharing options...
hovmoller Posted October 28, 2010 Report Share Posted October 28, 2010 Did I misunderstand something in Alans post or did it not answer the question.. I found the facts about how chlorine works in water interresting but I believe the question was whether people use de-chlorifiers for their tropical fish tanks. I am also curious to what large scale fishkeepers usually do? and if they do how do they do it? Quote Link to comment Share on other sites More sharing options...
livingart Posted October 28, 2010 Report Share Posted October 28, 2010 i use the hose from simply discus website to make an anti- chlorine treatment Mix 120 grams of sodium thiosulfate crystals per 1 gallon of water. Then use 1 drop per gallon for tank water. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 28, 2010 Report Share Posted October 28, 2010 Sodium thiosulphate is the active ingredient in these water treatments and converts chlorine and chloramines to relatively harmless chemicals (sulphur and hydrochloric acid). I think the answer you are looking for is that people are divided about treatment. Some do treat and some do not. The reason for my post was that many people think that the chlorine will evaporate and all will be well, so I was pointing out that it is not that simple. In the end you pays your money and takes your pick. Livingarts treatment will be by far the cheapest way to treat large volumes of water.

Joshlikesfish Posted October 28, 2010 Report Share Posted October 28, 2010 i use the hose from simply discus website . That sounds a lot cheaper then the petstore stuff Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted October 28, 2010 Report Share Posted October 28, 2010 I use prime. It works out far cheaper than aquaplus and stress coat. When you have thousands of dollars of fish in a tank, a few dollars for peace of mind is well worth the price. Quote Link to comment Share on other sites More sharing options...
Joshlikesfish Posted October 28, 2010 Report Share Posted October 28, 2010 When you have thousands of dollars of fish in a tank, a few dollars for peace of mind is well worth the price. Thats what I was saying to you the other night Aqua, only use it for the expensive fish. Don't bother using it on the cheap ones unless you really want to be safe Quote Link to comment Share on other sites More sharing options...
AquaLife Posted October 30, 2010 Author Report Share Posted October 30, 2010 ah, thanks for all the respond. I believe I've used sodium thiosulfate crystals before, it's like broken pieces of crystal stick. That was 15 yrs ago and I don't really know what it's call but sold at pet shop in Asia to breeder, off the counter. Any idea where can I get that here in NZ or even the prime that phoenix is using. I'd prefered the water treated for all my fishes, lol. I've set up a fish room in my garage. Although I filled my gold fish pond (outdoor), up directly from the tap(untreated) but I'm kind of worry to do the same with my tropicals. Presently I store water on my top level tanks for 2 days, hoping for the chlorine to evaporate but I know it isn't that simple. Quote Link to comment Share on other sites More sharing options...
Zev Posted October 30, 2010 Report Share Posted October 30, 2010 I get my sodium thiosulfate off a guy on TradeMe who sells it to neutralise bleach when washing clothes, I think 500g cost me something like six dollars, it is as you describe it, like broken clear rods. Prime should be available from any LFS that stocks Seachem products, if they do not have it on the shelf they should be able to order it in for you.

danval Posted October 30, 2010 Report Share Posted October 30, 2010 I just let the water stand for 48 hours and the chlorine dissipates. No problems as of yet Quote Link to comment Share on other sites More sharing options...
AquaLife Posted October 30, 2010 Author Report Share Posted October 30, 2010 This is fantastic . I'll look up for them at LFS or TM. Now I can sleep better knowing that the water changed is treated Quote Link to comment Share on other sites More sharing options...
malevolentsparkle Posted October 30, 2010 Report Share Posted October 30, 2010 it never crossed my mind to not treat water to remove chlorine, after all they put it in there to kill stuff. Quote Link to comment Share on other sites More sharing options...
AquaLife Posted November 1, 2010 Author Report Share Posted November 1, 2010 Yeah, back from where I come from we HAVE to or you'd lose the entire stock but I was surprised when told I dont have to here in NZ. I've tried with my pond goldfish which seem to survive well but with tropicals I'm concern as it can wipe the entire stock off with one bad water. I believe at times they do use more chlorine to treat the water, esp after heavy rain. Definately not worth the risk as they deserve to live not just survive, worst to get them killed.

Zev Posted November 4, 2010 Report Share Posted November 4, 2010 Sodium thiosulfate at about two pounds dissolved in a total volume of one gallon, used at one-two drops per tap gallon is about right.

alanmin4304 Posted November 4, 2010 Report Share Posted November 4, 2010 That would be American gallon I assume---not that it would be that critical. Quote Link to comment Share on other sites More sharing options...
