Thank you I understand now much better what I am dealing with. Back to my original Questions. 1) Town supply (Treated to make it less toxic) or 2) rain water collection I understand I might have to add some trace elements to the rain water but that seams to be the more natural option then try to put chemicals in to take out other chemicals. Or do I get this wrong?

Hello thanks From where in the us or do they sell locally the same? http://nzchemicalsuppliers.co.nz/list/s ... iosulphate

Hello Thanks for all the input. So really either way is OK for what I hear here. Well might keep a look out for a cheap tank on tm always can use it in the garden anyway. Just don't like to add more chemicals then I have to. And I sometimes smell the chlorine more then on other times. I guess I could always fill up some containers a couple of days before the water change and let it gas out just have to get better organized.

Hello, I am new to this forum. I have a question. Recently I have moved house and we are back on town supply on the North Shore Auckland. I was on tank water before and had no problems. So here is my question. Out of the following options which one would be the better way to go: 1) use town water and just treat it 2) buy a small rain water tank and just use it 3) buy a rain water tank and use an RO system to be sure (got one with the tank I bought but would need to replace all the filters etc) So basically my question is it a good idea getting a rain water tank and is the rain water in Auckland OK to use straight into the tank or does it need extra filters etc. The house had a UV filter etc but just for the fish that would be to expensive. Currently I have African Cichlids but at some stage I want to go marine when the finances are back in order in a few years i hope (houses are not cheap these days ) Thanks for you feedback.
