Space permitting .... set up a tank and fill it with water & tons of live rock and some live sand including macro-algae leaving enough room to add the water from your monthly change ..... the size of the tank should be at least four times what your monthly water changes add up too, but bigger is even better ...... maintain the tank as you would any healthy aquarium minus any expensive filters or gadgets and keep the water circulation very high .... let the live rock & algae do it's thing and enjoy what materializes ..... when you do the first water change after setting up this tank ... put the waste water into it ....... and the second time you do a water change ... use the water in this tank to replacie what you removeand put the "new" old water into the live rock tank ..... suffice it to say that keeping the exchange water tank healthy is very important (but easy) even to the extent of adding supplements ... and will make a surprisingly enjoyable aquarium with other unique possibilities unto itself! Besides saving you tons of money over the long haul.
