My old system I went over a year with out a water change ... new one has been up and running sense Sept and only did the first one a couple weeks back .. depends on the BIO load ... how many fish how often and how much you feed, water volume, and filtration .. mechanical .. or natural... and what you have for a clean up crew, if you have Macro Algae ...many different factors ...

I varried from 1 per month to 1 per year.. no real differance as loong as you adding the depleted minerals with a Ca reactor or by dosing.

WOW, if this is real, but then why does all fish shop staffs recommend people to do water change? Or do you need a huge skimmer / refugium so one can get away from water change?

Water changes facilitate the addition of trace elements and removal of waste. Even if you can have a healthy tank without regular water changes there is no real reason for most people not to do them. It's not like you need to do them daily/weekly, so compared to other types of tank maintenance you really don't invest a lot of time into them in the grand scheme of things.

Reef tanks require the removal of organic waste & detritus and as Steve said, the replacement of depleted minerals or such.

How thats achieved is variable. Water changes, good skimmers, large algae refugiums or algae turf scrubbers, carbon, ozone and the replacement parts handled by again water changes, reactors or the addition of 2-part supplements.

Most of the experienced aquarists use a combination of water changes & filtration to achieve beautiful tanks such as those displayed in our feature,s.

I very rarely do water changes(Last one over 6 months ago).
Both of my systems have skimmers, I add minerals and my livestock is doing great.

same reason as they recomend you change out your bulbs befor you need to.. makes them money.

you do frequent water changes you buy more salt.

remember water changes are a tool and you still need them, but with the right equipment you can extend the time between them.

One very experienced reefer put it into prospective for me once.

He said changing your water is like opening a window in your house after a long winter, you don't have to but the fresh air sure is nice.

Wonder what in-land public aquariums do? Realize we're talking larger volumes and that dilution/solution/pollution thing, but the costs and efforts for a 10% bi-weekly change on a 10,000g system...
