Cricketman Posted July 28, 2009 Report Share Posted July 28, 2009 http://www.hach.com/hc/view.knowledge.b ... 3BL+to+ppm I was right! :bounce: but again there are some who say that fish shouldnt be exposed to levels above 0.003ppm. which i think is too far, but that is my opinion. mature tanks have organic carbons that "mop up" the free chlorines, so if your adding water to a mature tank ie water change, it is safer than if you were to add fish straight to a new tank filled with tap water (as i said, new tanks are exceptions) though most of us are not going to do that anyway (cycling etc). O, and to further my own discussion on the SA/volume ratios, that means that a hexagonal tank or fish bowl, or any tank with a small surface area/volume ratio, if you have one, is probably the only time i would highly recommend almost to the point of insisting bucket changes with high aeration before adding to your tank, or using the chemicals. darn my useless spelling... re-edited Quote Link to comment Share on other sites More sharing options...
matthewY Posted July 29, 2009 Report Share Posted July 29, 2009 I had used somethign similar, using an old benchtop filter attachment to teh tap and running some standard clear pvc hose to the tank. pretty sure the attachment is easy to find and comes with a leaver for notmal tap use and to switch to teh pvc hose. The setup is always atached and not as noticiable as the hose is not too thick and is clear. This setup also allows you to easily "run" water to get rid of the water sitting in your pipes before redirectign to teh tank. Regards to aging water.... I dont see why you cant use an old (maybe clear :-) container floating /attached to the insides of the tank to store water (hidden if possible), the new tapwater is hosed into this container and the water in there overflows out through a few drilled holes near the top of the container. This means that you are aging a portion of the water before it hits the tank... so say if you change 10L every night and assuming the floating container holds 5l then roughly 5L of the 10L entering the tank would have been left over from the night before... Just an idea.... Quote Link to comment Share on other sites More sharing options...
David R Posted July 29, 2009 Report Share Posted July 29, 2009 My word, how many times has alanmin4304 gone over the whole chlorine thing and yet here we are having the same old conversation... viewtopic.php?f=4&t=25846 viewtopic.php?f=4&t=36035&p=394279 viewtopic.php?f=4&t=30431&start=15 viewtopic.php?f=4&t=35656 In short, chlorine doesn't really evaporate, it just changes into something equally as harmful. That said, many people [myself included] use dechlorinator at a lower dose or not at all and seem to get away with it... Quote Link to comment Share on other sites More sharing options...
