第五章(13/14)

                                                                                                                       “我正想问呢。”喜子说“下面摆放火山岩，是因为火山岩颗粒之间的缝隙大，形成了足够的有氧空间，利于硝化细菌的培养和各种好氧菌的生存。同时避免了长时间以后出现的底层死化，利于活化底层。中间的草泥丸，如果放在上面的话，酸化和软化功能会在3-4个月之内消耗殆尽。把它放在中间会减低功能损失的速度，进而延长起效的时间。上面的ADA不用我说了吧？”
                                                                                                                                                                “我明白了，哥，你真高。”
                                                                                                                                                                “呵呵，拍马屁”我笑着给了喜子一下子。
                                                                                                                                                                “我说真的呢。很多人只知道这么摆，但是说不出来为什么。听你一说，简直是一举好几得了。谢谢哥，我没白来。”喜子高兴的表情不像是在说假话。
                                                                                                                                                                “那我们还没明白呢？”小梅抗议着。
                                                                                                                                                                “家里的自来水太硬，呈弱碱性或者中性，不适合养短鲷。短鲷需要偏软偏酸的水，家里的水不合适，草泥丸和ADA泥都是用来软化和酸化水的。草泥丸软化和酸化的能力比ADA强大，但是释放的快，很容易失效，温度越高失效越快。ADA虽然失效慢，但是功效有点小，好在还算稳定。我把草泥丸放在ADA下面，就是想让草泥丸释放的腐殖酸会慢慢地被ADA吸收，再借由ADA的稳定释放特性，缓慢的释放到水里。这不是一举两得了吗？”
                                                                                                                                                                “哥，你真行，我有学会了一招。”说着喜子冲我伸出了大拇指。
                                                                                                                                                                “小梅开始说你什么都懂，我还不太相信呢。现在看来，我有点信了。”宝宝说。
                                                                                                                                                                “你就应该不信，没有人可
