David R Posted November 15, 2010 Report Share Posted November 15, 2010 Seachem Prime is the most economical off-the-shelf treatment. Quote Link to comment Share on other sites More sharing options...
Chug Posted May 1, 2011 Report Share Posted May 1, 2011 Seachem Prime suggestion? would other people also suggest this? who uses this? Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted May 1, 2011 Report Share Posted May 1, 2011 I use it. Works a charm, and if you have hundreds or thousands of dollars of fish in a tank it's worth the peace of mind. Quote Link to comment Share on other sites More sharing options...
cichlid7 Posted May 1, 2011 Report Share Posted May 1, 2011 Yes i am using that now for chch tap water. somewhere around $40 for 250ml - 5ml treats 200L of water very very cheap Quote Link to comment Share on other sites More sharing options...
David R Posted May 1, 2011 Report Share Posted May 1, 2011 I don't even use it at that strength, I put 5ml in my 220L barrel and then add another 50-200L of tap water depending on which tank it is (250-400L total WC)... Quote Link to comment Share on other sites More sharing options...
the-obstacle Posted May 1, 2011 Report Share Posted May 1, 2011 I don't even use it at that strength, I put 5ml in my 220L barrel and then add another 50-200L of tap water depending on which tank it is (250-400L total WC)... That's pretty much how I do it but I'm really only changing 20-30 litres. The first 10 litres gets the .3ml the dosage says to use then I keep topping up the bucket as it gets low. I've never had any problems with this approach. Quote Link to comment Share on other sites More sharing options...
hovmoller Posted May 1, 2011 Report Share Posted May 1, 2011 How much is Seachem Prime? I recently bought 2L Nutrafin Aqua Plus on TM for $38.50. I thought that was a pretty good deal. Quote Link to comment Share on other sites More sharing options...
the-obstacle Posted May 1, 2011 Report Share Posted May 1, 2011 It's not cheap but you use hardly any for each water change. I think my 150ml bottle was just under $20? Quote Link to comment Share on other sites More sharing options...
hovmoller Posted May 1, 2011 Report Share Posted May 1, 2011 Seachem Prime (HFF website): 250ml = $34.30, 5ml treats 200L = $0.34/100L Nutrafin Aqua Plus (on TM): 2L = $38.50, 5ml treats 40L =$0.24/100L :smln: Quote Link to comment Share on other sites More sharing options...
David R Posted May 1, 2011 Report Share Posted May 1, 2011 I think the 500ml (and 2L) bottles of prime may be better value? Although comparing product prices from a retail store that stocks fish and livestock to a TradeMe garage trader is hardly a fair comparison..

waterlogged Posted May 1, 2011 Report Share Posted May 1, 2011 I use it on all my tanks, seesm to be lasting alot longer then what I used to use Quote Link to comment Share on other sites More sharing options...

spoon Posted May 2, 2011 Report Share Posted May 2, 2011 lol had to laugh at that but have a look at the seachem site apparently when sodium thiosulphate reduces chlorine compounds it can produce ammonia so seachem prime also contains an ammonia binder http://www.seachem.com/Products/product_pages/Prime.html Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted May 2, 2011 Report Share Posted May 2, 2011 What about this: Guest Editorial According to Roddy Conrad: Sodium thiosulfate instantly takes care of the chlorine in chloramine, as well as straight chlorine. The reaction to get rid of the chlorine with either chloramine or chlorine is instantaneous on mixing of the sodium thiosulfate and the chlorine or chloramine. The reaction of sodium thiosulfate with chloramine produces ammonia. Assume you are doing a 20% water change and there is 1 PPM chloramine in the water. 1 PPM chloramine neutralized with sodium thiosulfate becomes 0.2 (20% water exchange) times 17/51.5 (molecular weight of ammonia divided by molecular weight chloramine) = 0.06 PPM ammonia level in the pond. 0.06 PPM is too low to even measure, and is safe for the fish anyway! My point is that it is perfectly safe to dechlorinate with sodium thiosulfate unless you are doing a 100 % water change and there is a huge 5 PPM chloramine concentration in the makeup water. Only then can the ammonia from the chloramine reaction with sodium thiosulfate get up to a 1.5 PPM ammonia level to give a possible real fish problem. Even then, please remember koi shipped in bags normally arrive at their destination in water that is 5 to 10 PPM ammonia level by measurement, and that is done all the time by the koi handlers without giving it a second thought. Yes, that level can do damage to the fish if you allow it to continue, no argument about that. So all those warnings about using sodium thiosulfate to dechlorinate water containing chloramines is just so much hype from folks making a profit selling the ammonia binding products to my way of thinking about the actual technology in action.

R32GOTMLK Posted May 3, 2011 Report Share Posted May 3, 2011 this might be a noob question but is there a test for testing water for chlorine? :oops: Quote Link to comment Share on other sites More sharing options...
bdspider Posted May 3, 2011 Report Share Posted May 3, 2011 Google says yes. If you're not sure if you do, you probably don't. It's a very obvious smell if you do, feels like I'm at a swimming pool when I take a shower at home. What suburb are you in? Quote Link to comment Share on other sites More sharing options...
