Tap water okay at first ?

RO stands for Reverse Osmosis.

When you swapped the sand beds this could have removed alot of your bacteria that break down both ammonia and nitrite did you keep an of the old bed in there in bags? Also if you dont have much live rock most all of your bacteria will be on the sand.
 
if you test your tap water in your area for all possible contaminants you could use it in your tank, i have used nothing but tap water and a salt mix and i am keeping LPS that look amazing, it has a lot to do with where you get ur tap water from in a city you may not be as lucky
 
I didn't bag up the CC, but left several pounds in there mixed into the sand. I have around 20lbs of live rock in the tank, and a fluval 404 filter (which I left really dirty on purpose). Hopefully the levels will go down. The fish are all eating well. My green brittle star had some splotchy patches on his body, but he looks to be ok. Is it too early to add some more LR? My goal is to eventually have enough LR and add some good lighting to make it a reef tank.
 
<<Until there is a RO process that is discrete, clean, and easy easy to use, forget about it!>>

Er, my RO unit just sits in my garage chugging away to itself. Apart from turning the tap on/off, it couldn't be easier to use, and it's very clean coz it's all self contained (just change the filters every 18-24 mths).

<<NSW is just fine.>>

What's NSW ? (forgive ignorance) N? S? Water ?
 
Nev

That sucks. I live next to the Seattle Aquarium, and they sell NSW that's been UV filtered for 5 cents a gallon.

Maybe I'll look into the RO units again sometime. I've just seen Phil's at Coral Beauty and he has pipes and tanks and tubes running all over the **** place.
 
Ive set my RO up in the garage (gotta sink there) .... there's one pipe from the tap, a red waste pipe that goes down the sink, and a blue pipe that goes into my (at the moment) bucket. I admit the blue and red pipes are a bit gangly, but it's in the garage so WTF, plus I intend to tidy them up a bit and wire them a bit more permanently.

Whilst on the subject of RO, at this current second I'm slightly miffed .... I've just tested the Nitrate of my tap water (20 mg/l) and the output of the RO unit (12 mg/l) .... I'd have thought the RO unit ought to reduce the Nitrate more than that .... (assuming test kit is accurate of course). Hrumph.
