新手求助金龙鱼换水问题本人订了一个1.5*60*80的缸，水位估计在70左右，准备养金龙鱼和印尼虎，向大神们请教换水问题，请各位解答！ 北方，自来水里有氯气，上午特多，下午晚上会好很多。鱼缸水大概有620升，一周换一次水大概130升，请问：直接用天然气热水器里的水，调好温度直接加行吗？时间长了对鱼的健康和发色有影响吗？如果准备个容器困水的话，130升水得多大容器啊，厕所放的话估计是放不开，其他地方更别提了。家里目前有个大桶，估计也就几十升水，旁边也能放个一样大的，有没有"必要"弄个矩形的容器?如果困水的话，还有个问题，担心困的水和缸里水有温差，这样的话是不是兑点热水？困水的话，只是放个充氧泵爆氧行吗？
欢迎各位高手指点！
