The most likely problems that an aquarist will be faced with, when it comes to keeping a saltwater aquarium, is that a power failure may occur, the tank may begin to leak, or the aquarium saltwater becomes polluted or the heaters begin to overheat. The other thing you need to think about, is that it is going to be very difficult for you to determine whether there is a problem or not, and so regularly monitoring of the aquarium is advised.
Should any kind of emergency arise in your saltwater aquarium, then it is crucial that you make sure all the aquarium saltwater fish and marine life in the tank are able to cope with the situation. Along with keeping a close eye on the fish and invertebrates, you need to make sure that the corals and live rocks in the aquarium are okay as well.
How To Deal With A Power Failure In Your Aquarium Saltwater Tank
You could lose power to your aquarium at any time, and unfortunately there is nothing that you can do in order to prevent this from happening. What is important,, however is that you make sure that the aquarium saltwater remains aerated, whilst it is without power. Most power failures will only last for a few minutes or hours, but if they last up to 24 hours, most aquarium saltwater fish, plants, and other marine life will be able to cope with this particular situation.
The best way to aerate the aquarium saltwater when the power fails, is to use a battery operated water pump. These pumps help to dissolve the oxygen in the water so that the right levels can be maintained at all times whilst no power is present. Because the heaters will not be working, you also need to make sure you help the water to retain as much heat as possible. This can be done by wrapping the aquarium in a sleeping bag or thick blanket. What you must never do whilst there is no power to your aquarium, is feed your aquarium saltwater fish and marine life, as the filtration system will not be operating.
Dealing With Your Aquarium Saltwater Overheating
If you discover that there is a problem with the heaters in your aquarium which are causing the water to heat up too much, don't be overly worried unless the water goes above 86 degrees Fahrenheit, as generally most aquarium saltwater fish and marine life can cope with this. However, it is far better if you are able to avoid this problem in the first place.
Ideally, rather than having just one large heater, make sure that the aquarium saltwater temperature remains constant. It is far better if you have two medium or small sized ones. Certainly when you are regularly checking the aquarium, you will be able to immediately see if there is a problem with either of the heaters that you have in your aquarium.
If you do find a problem that has caused the aquarium saltwater in the tank to overheat, then you should either turn the temperature down on the heaters, or turn them off altogether. Also, it is vital that you remove some of the hot aquarium saltwater (around 20 to 50% of the tank and keep it). What you now need to do is put some bags of ice into the aquarium in place of the water that you have removed, and these will help to bring the temperature down to an acceptable level. After this has occurred and the aquarium saltwater you kept after removing it from the tank has cooled down sufficiently, then you can slowly add it back to the aquarium once more.
