Yes and no... it's better in some ways (being the "real" thing), but there is some risk of introducing things (pests, etc.) you don't want. I would use a UV sterilizer... or perhaps just a diatom filter to remove larvae, "bugs," etc. On the other hand, some of that stuff (microplankton) might actually serve as quality food for your corals and other tank life. So how's this for a vague answer, huh? I would say it's "safe" but has some risks you could likely manage with additional care/filtration.

ok, but is there a way that you could cleanup the NSW before puting it into your tank?

Yes - Occelaris - run a small skimmer in the container (if possible), or pump through a sediment filter (standard water filter). You can also run it through a UV sterilizer before pumping it through the sediment filter. IF YOU LIKE.

Me - I just leave the water for a few weeks that the die off settles at the bottom, and then siphon it out of my 25 litre drums into my tank's sump.

i like your method more, so if i leave it for weeks then would it be considered more safer, would nitrate, nitrite and amonium levels not be high in that water due to the die off?

i use nsw for financial reasons, i do not filter it.. it is fine and i collect it myself near blouberg in the cape. if u are scared of introduction of bugs just think of the frags and fish and what u introduce with them.

hi mandarinman
yes i too would like to use nsw but was skeptic about the bugs ect
but i also wanted to use nsw as its more a natural environmental element
fpr the fish, im going to run a FOWLR tank and ive also considered nsw to be a cheaper option for me, did you experience any problems with the nsw in your tanks?
could you tell me how long after you collect the water do you use it? do you run a test on the water before introducing it to your tank?
thanx

hi mekaeel

ive been reading your forum on "my tank"
must say excellent tank, ive seen you started with NSW but as i read on you became sceptic,i didnt read the entire forum but are you now on synthetic salt mix or are you on NSW still? also if you are still on NSW then how regularly do you do water tests?
