A lesson that all aquarium hobbyists learn the hard way is that taking care of a fish tank can sometimes prove to be a challenging task, especially a saltwater tank. Many things can go wrong, such as algae outbreak or even behavioral problems with your specimens. While having to deal with marine fish tank issues can be annoying, on the bright side of things, you can prevent them all from happening by preparing ahead of time. With that said, today we are going to present the top four most common marine fish tank issues and show you how to fix them.
#1 How to Deal with Algae Growth
When it comes to fish tank issues that aquarium hobbyists fear the most, then algae growth is the biggest problem. Algae growth is a problem for all types of fish tanks, and if left unchecked, the algae will cause many issues that can lead to destroying the entire ecosystem. Fortunately, there is a simple way to deal with this issue. Since algae is a living thing, then it needs specific nutrients in order to grow. This is why performing regular water changes will help you prevent aggressive algae growth.
#2 Avoid Sudden Changes
The first rule in the aquarium hobbyist’s rulebook is to avoid sudden changes. We are talking about drastic changes in temperature and the pH of the water. If you haven’t been paying attention to the tank’s water parameters and it is now out of control, then the best way to solve this problem is to correct it gradually. All the organisms in your saltwater aquarium will be affected if you make any major changes to the water, and this will stress your fish, which can cause health problems. In addition, the ideal temperature for fish tanks is in the range of 72°F to 84°F.
#3 Overloading the System is Always a Bad Idea
While cramming lots of livestock and live rock into your aquarium might seem like a great idea, this isn’t actually the case. The best way to increase the population of your marine fish tank is to add new specimens slowly. If you don’t follow this rule and overload the system, then this will lead to the “new tank syndrome.” This is a term that is used by experts to describe when the ammonia produced from the bio-load is too big for the nitrifying bacteria to consume.
#4 Marine Fish Diseases
One of the biggest problems that people who own marine fish tanks will have to deal with is diseases. The two most popular diseases for marine fish tanks are velvet (Amyloodinium ocellatum) and ich (Cryptocaryon irritans). These diseases can prove to be fatal, and if you notice that one of your specimens is sick, then you should make sure to quarantine it as soon as possible. The reason behind this is that velvet and ich can quickly spread to all your other species. We also want to point out that poor water quality can weaken the immune system of your fish.
