    This is a thread that I want to start (and not encourage anyone to do it as such) regarding the maximum time period between waterchanges you had thus far.

    Meaning:

    1.)What is the longest time period that someone with a well established coral reef went without a waterchange????.

    2.)And did you see a positive or negative response to the coral growth???

    My tank is now a year old and I have still not done a single water change. All inmates are doing just fine.

    Surely you replace all the trace elements that get used up? And what do you add in?

    I havent done a water change for the past 3 months, been very busy. Will do one next week though! Technically nothing has died, but its easy to c that the inhabitents dont have that marine sparkle, they look a bit like fresh water lol. I definately wont repeat this experience!

    Longest I have gone is 10 days.

    My corals don't like it if they don't get their regular 10% WC. I also notice the "horrible" Water parameters rise pretty quickly at day 10.

    I know of FO systems with NO LR. Which have been heavy stocked running for over 2 years with no water changes and hardly any losses. As for a Reef my longest was 2 months. Once you do a large water change I have noticed corals extra-ordinarely extend themselves (Only when water changes are performed). This must be some sort of re-aclimatazation they go through?

    Can also be due to detritus being stirred up, have seen with corals when I blaster the reef with a PH or turkey baster.

    5 mths but did add suppliments -iodene, strontium, ca, mg, trace.
    All corals did fine and other livestock aswell.
    I do believe though that 10% a month should be a min with add of above suppliments.

    I still believe in regular water changes simply because it happens in the ocean on a daily basis. We're too busy and it costs too much to do daily, so the next best thing is weekly - that's what I do anyway, 10% every week.

    Warren, what params do you measure, and how bad do they get?

    The reason I ask is that I've not done many water changes recently, but my params are still fine (NO3 = 0.0, PO3=0.05). Even so, I have a horrible hair algae problem, and can see when my corals need a water change (every two weeks or so).

    Q

    My Nitrates level start increasing and then comes the algae.
