livingart Posted March 21, 2014 Report Share Posted March 21, 2014 Clean natural salt water can be collected locally in many parts of New Zealand; you just need to ensure it is clean. Collecting about half an hour before high tide is best but not after any recent rain as this can include contaminants from land runoff. Near river mouths or areas where there is a lot of boat activity should be avoided as well for the same reasons. Collected water can be stored indefinitely in sealed containers away from any light sources. If you are worried about parasites ( I've never had an issue) put water through a 1 micron filter as all parasites are bigger than2 microns The task of collecting water can be made easier by using a 12V pump that plugs into the vehicles cigarette lighter and then pumping into large sealable, food grade plastic containers. Collection points around NZ., used by other local reefers. https://www.zeemaps.com/map?group=2833137 Quote Link to comment Share on other sites More sharing options...
hovmoller Posted March 21, 2014 Report Share Posted March 21, 2014 Excellent! How long does that one take to fill? Quote Link to comment Share on other sites More sharing options...
livingart Posted March 21, 2014 Author Report Share Posted March 21, 2014 about 20 mins, big 12v bilge pump Quote Link to comment Share on other sites More sharing options...

Yeah, 1000L container is the way to do it. Actually 2-3 would be best, hard to pull a 1000l tank full of water off the trailer. And I think I'd be tempted to fill the storage tanks with a bunch of liverock. Quote Link to comment Share on other sites More sharing options...
anthony law Posted June 17, 2014 Report Share Posted June 17, 2014 mark has a bath at the same time. :ske: :dead%fish Quote Link to comment Share on other sites More sharing options...
junglejim Posted June 24, 2014 Report Share Posted June 24, 2014 Be careful about buying those 1000l tanks. Most have had nasty chemicals in them. I just bought one that has had ethanol, which I am hoping won't effect the fish except get them drunk! Quote Link to comment Share on other sites More sharing options...
#!CrunchBang Posted June 24, 2014 Report Share Posted June 24, 2014 Ethanol should just evaporate away. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted June 24, 2014 Report Share Posted June 24, 2014 Also very water soluble so would go away with the first rinse. Quote Link to comment Share on other sites More sharing options...

kiwis Posted July 22, 2014 Report Share Posted July 22, 2014 Doesn't this introduce parasitics and other nasties to your tank? Do you have a reef tank? Quote Link to comment Share on other sites More sharing options...
Godly3vil Posted July 22, 2014 Report Share Posted July 22, 2014 Doesn't this introduce parasitics and other nasties to your tank? Do you have a reef tank? It could but I've never heard of NSW causing issues even in a reef tank. It's a pretty common practice among reefers to use NSW as the price is a fraction of creating ASW.

cichlidman2010 Posted August 30, 2014 Report Share Posted August 30, 2014 What percentage of fresh water generally needs to be added to NSW to adjust salinity and deem it appropriate for aquarium use? I live on the North Shore in Auckland if that helps Quote Link to comment Share on other sites More sharing options...
livingart Posted August 30, 2014 Author Report Share Posted August 30, 2014 get a refractometer for accuracy in salinity testing Quote Link to comment Share on other sites More sharing options...
