Finding a container is not a problem, it is finding a source of the water to
put in the container!
Purified water just is NOT cheap here, Just water purifiers for your home
taps that you can buy at hardware stores can start at around $399.


I use ocean water also.
I do use a small amount of RO/DI, but with enough fresh ocean water
you can practically forget about it....I was listing what I use to
haul mine from the sea.
I got a great RO/DI filter from Canada for $100 US. How is shipping
to AU?

Shipping is pretty expensive shipping them over here from what i remember.
We looked into buying one from in the US and shipping it here but from
memory shipping nearly doubles the cost..
We did find a place in AUS that has them and the prices are not too bad, but
the wallet refuses to let go of the cash just yet. hehe
Have a few other bills etc to get out of the way first, which is why i was
asking about Ozone and UV efficiency against the weed.

Looks like I'll have to get a Water Filter....
I'll also remove the Canister Filter and Hangon Filter just in case it IS
feeding the problem..

You don't need to remove canister and hang on. They are good for
circulation. Just remove the media from them. If you remove whole media all
at once it can lead to amonia and nitrite rise because you removed oxidizing
bacteria and new bacteria didn't have enough time to colonize in numbers
needed for amonia and nitrite reduction. Remove it slowly over, say two
weeks. You can also put some good qualitiy activated carbon inside of
canister.
The fact nitrates are low is because of algae growing in your tank. They are
depleeting nitrate so you can't read it on your test but that doesn't mean
that your aquarim is not producing too much nitrate.
I'm also suspicious of mud. It also can produce nitrates. Especialy if it is
not something already tested in aquarium. You should let your friend to
experiment in his tank not yours.
It is common now among SPS keepers to run barebottom tanks to avoid buildup
of detritus that leads to nitrate problems. If you don't watn to have
barebotom then I suggest regular sifoning of crushed coral.
Ozone can help but it isn't mirracle. If you don't do other things right it
won't do much.
