No water changes
Has anybody ran a reef tank without doing water changes. I've ran into several people who claim that they do not do water changes they just top up evaporation. None of these folks had skimmers either. I bought a running aquarium with live rock from a lady who didn't know that I had experience with marine setups and before we sealed the deal she told me that it was important to not clean the sand or change any water. The rock was covered with nuisance algae. I did a 50 percent water change and washed the sand in the old tank water to get rid of all the dirt and stuff(the water was damn near cocoa) and 2 weeks later the algae was gone and then a month later every bit of exposed branch rock was covered with thick and bright purple coraline. the tank was about 5 years old. I just wanted to know what people on the board thought of "no water changes". I love water changes, everything looks new again.

I very very rairly do a water change on my reef. i just add the water to compensate for the evap, and thats about it. as for the sand bed, i do get my paws in there atleast once every week or 2 and mix it up a bit. not like a hurricane, just enough to release the nitrate gas pockets. then my skimmer goes into overkill mode for a few days, and then its clean again.
on the odd, occasion, i may do a water change, like when im starting another tank,i will take about 20% of my water and use it for the new system. and then just top off the reef tank with fresh saltwater. i have no algae problems, and never have had actually. knock on wood.

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 ...
