    Water changes....?

    I was wondering. If you did your water change and placed the used water in a large food grade container whould this water not cycle again. Thus resulting in New......used cleaned water that you could then mix back through your tank.

    Remember still a FNG (Freaking New Guy) so go easy on the responses.

    i would say no, dont do that.

    we change the water because you want to replenish your tank of trace elements, calcium and other good stuff.
    you also do this to remove toxic elements.

    also, if you did, you would also need to oxygen it and run a protein skimmer, and possibly charcoal..

    i'm new to this too.. but i think its not a good idea.

    moving.. so temporarily out of SW :b8:
    planning next tank, possibly 60x30x20 on 2x plasma.

    LIV is absolutely right. toss it out. its chalk full of metals/minerals and stuff broken down from some of the prefab foods we feed. corlas like a breath of fresh water once in awhile.

    Everyone seems to have their own ideas on water changes. Most agree they are necessary though. I do 20% every week. It allows me to feed quite a bit and I feel this is best for my tank.

    As long as the water going in is better than the water coming out- the more water changes the better IMO! I usually do 20 % every other week, and wish I did 20 % every week. And then every few weeks ( or months) try a BIG wc, like 40 %. Then you will see very happy critters!

    Moms got it .. I have read that for fish anyway that a change in water chemistry... even a quick one if for the better rarely harms them.

    Thanks to the above article, I am starting to do 20 to 30% water change every 2 to 3 weeks instead of 10% every 10 to 14 days. I did notice that the corals showed improvement - ie the brain was bigger than it had been after the larger water change.
