    I have no issue with NSW, but you need to check parameters before adding it to your tank.

    Maybe Leslie can give you more info one collection in bluff

    As far as I know, you don't need a permit to collect water from the ocean.

    No need for a permit. I collect weekly with no permit, make sure u don't collect close to any river mouth, don't collect after rain and i also don't collect when it's very windy . I like collecting at low tide so i can walk about 60m on rock's to get to clean water. Also don't collect the surface water ,get it as deep as your arm can go into the water.

    Nothing wrong with using nsw . Test the parameters to see what you add to your tank.

    The new i collect has a low .ph, slightly low ca and is 1.028sg , so i make those adjustments .

    Charl, have you tested other Params on the NSW here in CT?
    Nutrients, PO4?
    Just interested.
    Coz I agree you can adjust elements to suit reefing needs.

    @brentv,

    I have actually done a full range of tests and the no3/po4 is pretty much undetectable on salifert test kits. The CA of the water I collect is around 390-400 and the KH a bit low. I add buffer let it mix for a few hours, add CA and then add it to my tank. The SG is around 1.028 so I just add R/O.

    I have been using it for 4 years now and I have had great results but to be honest, I haven't been doing many water changes. I am however changing over to Seachem reef salt because I got a bit lazy and it is a mission to cart 50 liters of water to the car once a week. I can only collect during low tide which is not always possible.

    But as I have said above, I have nothing but good to say about NSW. :thumbup:

    I fully agree, there is nothing wrong with NSW as long as you collect on the right time!

    Can someone recommend a good 12VDC pump to pump NSW into a container, and a place where the NSW is relatively close to the road in order to pump the water, instead of walking with separate containers?

    I have a 500L horizontal tank that I'd like to use for collection, so using a pump to fill the container would be a bit better IMHO :tt2:

    Well...

    Firstly, there's nothing wrong with a long(ish) extension cable. Whilst there are a significant voltage drop on cables using DC power, thicker conductors means less of a voltage drop. So the long(ish) cable, is not really a problem to begin with, and neither are water tight connectors when the right things are used to make the connections with.

    Secondly, the pump is much more important than the long(ish) extension cable, as the pumps obviously won't be able to pump the water a very long distance, nor very high up.

    Thirdly, if you read my post again... "and a place where the NSW is relatively close to the road in order to pump the water"

    But anyways, perhaps there are more constructive and meaningful posts and suggestions.

    Research institute in sea point used to allow us to get water for mahala, not sure if they still do...
    the tap is about 3 meters from your car and you dont need a pump.

    Let us know more. Then I can tell you about our 12v dc pump. What distance and height you looking at?

    Look at boat bilge pumps.
    They are 12V, running from a battery as well. Maybe easier, although heavy to carry the battery down to the water than to lay out a lot of cable.

    Will it not be easier to hire or purchase a small genie that way you can use a pump with more head. @jono if u looking for a spot close to your car try Isipingo. Have always collected here.

    I started my tanks with NSW collected from Bayworld (PE), and still collect from them for the odd water change, I also collect from our rock pools if I miss the collection at BW with no ill effect to my livestock.

    It helps staying 900m from the shoreline.

    Research aquarium doesn't supply water anymore

    Why not collect from the aquarium? You can pull up next to the tap and won't need any pumps
