lduncan Posted October 19, 2004 Report Share Posted October 19, 2004 Well, I finally decided that I would check out NSW around ChCh. Here are the results from basic tests: Salinity 1.024 Mg 1110 Ca 300 KH 5 NO3 Undetectable PO4 Undetectable Other crap Untestable by me. Calcium is very low, Mg a little low for my liking too. Still no incentive to change. Layton Quote Link to comment Share on other sites More sharing options...

lduncan Posted October 19, 2004 Author Report Share Posted October 19, 2004 Corsier bay. It had the easiest access if you were to collect a lot of water. Layton Quote Link to comment Share on other sites More sharing options...
RnB Posted October 20, 2004 Report Share Posted October 20, 2004 would it be possible to change this thread to NSW around NZ then others could post here as well, I would be happy to test AKL on both a good day and after a week of rain :oops: Quote Link to comment Share on other sites More sharing options...

skuzza Posted October 20, 2004 Report Share Posted October 20, 2004 NSW in makatu is. Mg 800 in winter it seems to get a bit higher in summer.Best ever Mg 1000. Ca 400 at the lowest but never goes over 420. NO3 nothing PO4 nothing Quote Link to comment Share on other sites More sharing options...
Pies Posted October 20, 2004 Report Share Posted October 20, 2004 Don't forget to warm the water to 'reef' temprature before testing. Otherwise you params won't make a reasonable comparision. The bottom line is the water will be fine for the reef tank (proof in all the tanks using it). This 'issue' is all the stuff your not testing for 'petrol', 'onion', 'decaying bodies', 'urine', 'dead farm animals' etc. Sea water is sea water, give or take a few params it will be fine. Its the 'unknown' factor that makes it so exciting. Pie Quote Link to comment Share on other sites More sharing options...
dan_from_nz Posted October 20, 2004 Report Share Posted October 20, 2004 Pies do you know where it is good to get nsw from in wellington at the moment when i get nsw i go to the rock pools in between paikok and pukerua bay it seems pretty clear and fine but am unsure of what polutants are / could be there Quote Link to comment Share on other sites More sharing options...
Pies Posted October 20, 2004 Report Share Posted October 20, 2004 I would choose to get my water from the South Coast over the west coast. But when I do get my water I get it from 'fiti ray a' (sp?) park. Just collect on the imcomming tide, and not from stagnint rock pools you will be fine. Perhapps next time I go out you want to meet up? Pieman Quote Link to comment Share on other sites More sharing options...
wasp Posted October 21, 2004 Report Share Posted October 21, 2004 Just a comment about the low calcium mentioned by Iduncan, I've done a lot of testing of NSW myself, and found that where I collect, which is the Takapuna boat ramp, the calcium content can vary depending on conditions. With an onshore wind, calcium can be down to 280. However with a good offshore wind, crystal clear water collected just before high tide, calcium will be 400, and MG will also be good. Might be wrong, but my theory is that surface water is not as good quality as deeper water. So, with a good offshore wind on an incoming tide, the surface water is moved seawards, and deeper water is moved landwards, for collection at the ramp. That's my THEORY only, however, calcium and other levels will be good, at Takapuna boatramp anyway, if the following conditions apply - Strong offshore wind and water flat, water crystal clear, just before high tide. Some people will disagree, but I've found modest rain to have little effect on measureable parameters, including salinity, if the above conditions are met.

RnB Posted October 21, 2004 Report Share Posted October 21, 2004 I will def go tonight, was going to last night but got chatting with Brendan - (i am difficult to get rid of!!!!) and time passed.......... No not a zeovertz convert yet, just interested in all the opinions out there....... But its time to get a 200L barrel from barry and go collecting! I want to get some glass shrimps for my beta as well! where is the best place close to north shore? Quote Link to comment Share on other sites More sharing options...
wasp Posted October 21, 2004 Report Share Posted October 21, 2004 If you are going to Takapuna and want shrimps, go towards Milford and hang a right just before you get there down one of those streets like Saltburn that take you to the beach. There is some rock pools there, at night with a torch they are swarming with shrimp. Trouble is, you will want high tide to get water, and low tide to get shrimp.
