Stealth Posted September 15, 2011 Report Share Posted September 15, 2011 Hi team: Is it possible to use natural sea water a marine tank? but first filter it and clean it before using it in the tank... My idea: Using a 200L drum with a decent protein skimmer attached, cycle the natural sea water through a sump and then using it.... Obviously checking the salinity and diluting with fresh water if necessary.. Can this work? just thinking of a cheaper way in the long run.. Also does anyone know where to collect the cleanest sea water around Auckland? Thanks :nilly: Quote Link to comment Share on other sites More sharing options...
Morcs Posted September 15, 2011 Report Share Posted September 15, 2011 unless you feel like wading in the surf at takapuna... then you also have to be mindful of tides etc... how much water you need say per month? Quote Link to comment Share on other sites More sharing options...

Thanks :nilly: Yes, but if you have nice water dont bother "filtering or cleaning? it", it will be much better than the water in your tank. Your idea is simply not necessary. Simply dilute slightly and use. Alot collect from takapuna boatramp on a high tide, plenty of other places. Collect after a week or so of no rain (downpours) and just use it, lots do, and regardless on what some might say, i've heard of no-one having issues using nsw. If the water is murky or dirty, dont collect it, go back another time. Quote Link to comment Share on other sites More sharing options...
Jettin Posted September 16, 2011 Report Share Posted September 16, 2011 What he said ^^ Dont need to wade through any surf, just head to the takapuna boat ramp, you can collect from either side of the ramp without getting wet. Quote Link to comment Share on other sites More sharing options...

Personally, I try to collect as far away from any boats. Quote Link to comment Share on other sites More sharing options...
#!CrunchBang Posted October 5, 2011 Report Share Posted October 5, 2011 Can harbour water be used? Quote Link to comment Share on other sites More sharing options...
Rockerpeller Posted October 26, 2011 Report Share Posted October 26, 2011 With how many contaminants in Auckland harbour, I wouldn't risk it. If you ever get a chance go down by the motorway before the bridge and check the mangrove area. That alone will make you think twice about collecting in the harbour. I used to collect from Takapuna boat ramp myself with a bilge pump (got sick of wading out down the boat ramp to get it in winter). Quote Link to comment Share on other sites More sharing options...

Yet the dotterels and oyster catchers nest there. Quote Link to comment Share on other sites More sharing options...

Rockerpeller Posted October 26, 2011 Report Share Posted October 26, 2011 Yet the dotterels and oyster catchers nest there. Yes they do. But would you eat any shellfish from within the harbour? This isn't jab or anything, I'm just trying to get a point across. When it comes to reef tanks the smallest contaminant can wipe a tank out.

#!CrunchBang Posted October 26, 2011 Report Share Posted October 26, 2011 They have spent quite a bit of money improving the run off into an artificial wetland around there. Quote Link to comment Share on other sites More sharing options...
Rockerpeller Posted October 26, 2011 Report Share Posted October 26, 2011 Thats fine, and its about time they have started doing that. But the harbour doesn't flush well enough due to all the rivers feeding into the harbour. If you look over google maps and count how many rivers feed the harbour you will see why everyone chooses Taka boat ramp. Taka is tried and true, not to mention its far closer to open sea then the harbour is. The further away from harbours and rivers you get the better the water quality gets which is what we want for reef aquriums. Best way to check the water quality would be to use every Hanna meter you can think of, and compare the results. I don't think many NSW using Auckland reefers would risk hundreds to thousands of dollars of livestock, because they think the harbour is safe to use.
