There’s an old saying that only bad things happen quickly in a marine aquarium. That’s certainly true enough, but it’s also important to keep in mind that some problems that can affect the health and wellbeing of livestock tend to develop very gradually and almost imperceptibly over time. Here’s a quick (but by no means exhaustive) list of some of the sneaky marine aquarium problems that we must be vigilant against:
1) Downward drift in pH
Maintaining a稳定的ph在期望的8.2到8.4期间,需要仔细监控,认真的牲畜饲养和勤奋的维护。这些区域中的任何一个都会导致您的pH值偏离路线,并且由于储罐中的自然生物过程,趋势通常(尽管并非总是)向下降低。除了定期的水测试外,您对漂流pH的最佳树篱是:
- 进行定期的部分水变化
- Maintaining an appropriate碱度水平(在8至12 dkh之间)
- 在表面提供湍流的水运动以驱逐二氧化碳
- 避免过度喂养和过度喂养
2)光强度丧失
The gradual loss of intensity in aging aquarium lamps isn’t necessarily a big deal for fish-only and家禽tanks, but it can lead to significant problems in a reef system. Not only will the inadequate light level stress your photosynthetic invertebrates, but if you’re not careful, they can also be shocked a second time by the sudden increase in light intensity when you finally replace the lamps.
不要以为您会注意到水族馆照明的输出的差异,因为直到严重下降。最好根据制造商建议的时间表定期更换灯泡/管。
另外,请注意,在盖子和盖玻片上的水以及盐/钙堆积中的泛黄化合物往往会降低到达光合无脊椎动物的光水平,突然消除了这些问题(例如,使用activated carbonto polish the water or cleaning the lids and cover glasses) can cause a spike in light intensity that shocks the inverts as well.
3) Slipping salinity
Several factors can cause the salinity of a marine aquarium to drift gradually away from the desired value, among them:
- Failing to compensate for evaporation by topping off with fresh water
- Compensating for evaporation with salt water instead of fresh water
- 无法将替代水的盐度完全匹配到在水变化过程中被去除的脏水的盐度
- 添加或多或少的盐水比在换水过程中取出的盐水
- Failing to compensate for salt creep
Salt creep—the crusty buildup of salt on surfaces exposed to air and saltwater spray—is probably the salinity-reducing factor that, well, creeps up on hobbyists most often. Wiping away this buildup is an重要的常规维护琐事,但别忘了,每一点的盐蠕变哟u wipe away was once dissolved in the tank water. You need to compensate for this loss.
4)硝酸盐上升
All the issues we’ve discussed thus far have been related to falling levels. When it comes to nitrate, however, the level is always trending upward. That means, in addition to avoiding overstocking and overfeeding, marine aquarium hobbyists have to employ some sort of nitrate-reduction methodology to keep nitrate from gradually climbing to an unacceptable level.
Diluting nitrate with good-old-fashioned water changes is the tried-and-true approach. Other nitrate-reduction techniques, such as the use of a deep sand bed or an organic carbon source coupled withprotein skimming, can be helpful as well (though they should not be considered substitutes for regular partial water changes).
将您的水付诸实践!
The potential for such sneaky problems is one of the best reasons to test your water parameters on a regular basis. Remember, the earlier you catch one of your parameters drifting off course, the easier it is to rectify and the less stress it will cause your livestock.
