To put a lid on it or not to put a lid on it, that is the question!
Okay, with profuse apologies to the Melancholy Dane, the point I’d like to mull over in today’s post is whether it’s a good idea to use cover glasses on marine aquariums—you know, those oft-hinged glass or acrylic lids that are available in various dimensions to fit tightly atop aquariums of different sizes.
As with so many aspects of the marine aquarium hobby, there’s no all-encompassing right or wrong answer to this question. Suffice it to say that cover glasses may be appropriate in some circumstances but totally inappropriate in others.
要确定最适合您的系统的方法，请考虑以下覆盖玻璃优点和缺点：
Pros:
- 拥有盖玻璃就位可减少蒸发，从而减少淡水最高点的尺寸和频率，并有助于降低房间内藏有水族馆的湿度。
- 容易跳或从坦克上滑出的鱼保存在其属于的水族馆中。一些鱼类，例如鳗鱼，甚至是某些无脊椎动物，例如章鱼，是如此出色的逃生艺术家，以至于保持紧密的盖子是必须的。但是，对于许多鱼类而言，有玻璃/丙烯酸盖的替代品可能可以做相同的工作，例如，由某种类型的网状或筛选材料或塑料蛋箱制成的覆盖物。
- 灯具可以更好地保护溅射和腐蚀性盐喷雾剂。如果固定装置不配备保护灯泡/管子，则尤其重要。
- 盐蠕变没有盖玻片就可以前进，尽管它仍然会在封面本身上积聚。
缺点：
- A cover glass can reduce vital gas exchange at the water surface (think of the interface between the water surface and the air above it as the system’s “lungs”). Having an open sump and providing vigorous蛋白质脱脂can help compensate for this.
- 石灰沉积在玻璃和盐蠕变/丙烯酸有限公司ver reduce light penetration, which is detrimental to photosynthetic invertebrates. So, regular cleaning of the cover glass (anothermaintenance task）对于防止这种积累至关重要。
- A tight-fitting cover tends to trap heat, which can lead to unacceptably high水温，尤其是在温暖的季节。
- 蒸发减少。是的，这可能是一个骗局和专业人士，因为这也意味着蒸发较少的冷却进一步促进了热量积聚。缓慢的蒸发速度也可能是对滴水Kalkwasser补充的reefkeepers的骗局钙and碱度由于饱和的kalkwasser通常用于淡水顶级。
