    Let's say you live in land far from the coast.
    Tank is already for while. Is there any benefit to collecting natural sea water when on holiday,say 100L.
    Would doing a natural sea water change have any benefits to your tank. As apposed to regular tub salt water mix.
    If the answer is yes, How would you recommend transporting it.

    I don't see any harm in it. I think the only thing would be the transport time that could make the difference.

    TBH I don't think so. I have read on RC that we are better off with the salt mixes we use than using NSW due to the fact that our systems are closed set-ups and not as large as the ocean...

    If you looking to diversify your bacteria and critters etc. then you can take like a cup of sand from different established set-ups and it to yours.

    Oh well if i think logically nsw is as good as is gets. We as hobbyist try to immitate nsw. For critters etc i would imagine you would have better luck looking in rockpools etc. i have a friend that stays close to the ocean who uses nsw. He stores the water for months in big containers and uses as he needs. Just keep it out of direct sunlight

    If you running a coral tank,it's a constant battle to keep the CA,magnesium,alk,trace elements at favorable levels and thAn you decide to do 20 percent nsw change where levels are low so now everything drops,so now you have to dose all that chemicals to get it up again.do it with red sea pro salt mix where all your levels are high just makes sense.

    I'm just talking out of my head to lazy to look on the container lying in bed lol,it's the basic idea that topping up with mix full of the rite stuff is better than sea water and coarse it also depends on how big water change you do.
    Just giving my 2 cent:biggrin:
    Lots of people go the natural route but than you have to test again to c where your levels are at and dose and,and,and

    the problem with collecting NSW is you dont really what you getting if you dont know the area you are collecting from. also the time it would take to transport the water may lead to loss of the collected life and result in an addition of phos and nitrate. id stick to synthetic

    100L sea water is like extra 100kg plus you have in your car driving up. Plus the space the 4 * 25L drums would take up.
    Not really worth it.

    Although I did brought up a big tub of wet sea sand. Saved me a lot not buying aragonite. But it was heavy. Filled the tub inside the car boot. Drove uphill all the way to Gauteng. Used it in a new setup that still needed to cycle. Was it worth it? Money wise on the aragonite to fill a 3m by .6 tank, definitely yes. That would have been a couple of bags. Carrying the wet sand up the beach was a lot of hard work. Luckily I had my two sons helping me out and I paid them in Icecream. :biggrin:

    I will not do this for water. For the substrate, yes.
