I've done 2 water changes total in one year and they were only partials (~20%). I've had to start dosing because some of my corals have gotten massive but otherwise my setup has been great. I just went away for a week and had some neighbourhood kids feed my fish and it looks great still, no horror story this time.

don't need to now, you already did. :mrgreen: but some color ..... come on :rolleyes:

anyways I don't say you can go with out one but I definatly don't say you need to do it every month or week for that matter, if you have a good set up that is overskimmed, ect then you need to be the judge. do a couple at one month, then try two months for a couple then three months while keeping notes of different things as you go. this is what I did, and yes I did go a year once and that was sucessfull but shortly after that I had the heater incident and the sand bed removal.

I used to do 6% weekly water changes but my new skimmer pulls about 2 litres of dirty dark green gunk out of the tank daily so I'm always topping off with about 2.5 L of water a day.

So now I do 3% weekly water changes. Been about a month. Everyone still seems happy.

Hello all.Have had a 75 up and running for about 10 months. I have just started using NSW for changes(afterall we're surrounded by it!!!) The results have been great. Only have some soft corals and just venturing into that area. But the NSW is the way to go. No more salt for me. The tank just appears more vibrant. I advocate waterchanges big time, however I do 20% bi-weekly or so. Hello to all newfs here, we need more stores lol. I go on reefcentral often and kkinda forgot about joining here lol. Cheers

yay another newf:) where yua too on the rock??:welcome:

Dido! Cheers Ronnie:biggrin:

my 18 gallon which has a slim skim nano gets a 5 gallon water change with Royal nature once per week

*sigh* to live near a source of NSW. I once brought 4 litres of it home from BC in two pop bottles, but taking in to account the plane ticket and the fuel the plane burned to fly it over the mountains, it was probably the most expensive 4% water change I've ever done.

i wish i could someday have a tank plumbed directly into the ocean......

I'm trying to cut back but I still use about two buckets of salt ever three months. I mostly do micro water changes when I get rid of frags and larger ones when I need to fill my QT tank.
