After problems with “new tank syndrome” (high ammonia and nitrite levels) and the lack of proper water changes, parasite disease is the next greatest cause of defeat and distress among marine aquarists. Disease diagnosis and cure is a complex topic, and I refer you to my book, The Marine Aquarium Handbook: Beginner to Breeder, for more complete information. But I can provide a few tips here.

Most marine aquariums, small and large, require a heater all or part of the year. Make it a point to be aware of how the heater is functioning. Keep a small thermometer in the tank and check it frequently. Watch the little light on the heater. Make sure it goes on and off when the room is cooler than the tank. If it stays on all the time, the heater may be broken or it may be too small for the tank. If it never comes on, it may be broken or set too low.

There are two important considerations about temperature. First, a marine tank should always be within the range of 75 to 85 degrees Fahrenheit. Many tropical marine fish and invertebrates are stressed if temperatures go below or above this range, and many die if the temperature dips below 70 or above 90 degrees. Second, the temperature should not change with great rapidity. For example, suppose the aquarium heater ceases to work and you find the tank at 66 degrees Fahrenheit one morning. Many or all the fish may well survive if the temperature is increased to 75 or 80 degrees over a period of a couple of hours, but moving them immediately into 80-degree water may well cause immediate death.

It seems like we have been getting a lot of new posts on the forum about basic saltwater aquarium setup information. I've written this saltwater aquarium tank guide to hopefully make it easier to understand the start up process for those just getting into marine tanks. I'll make it a step by step article so it is easier to follow. The picture above is my 120 gallon reef tank.A saltwater aquarium can definitely be more expensive than a freshwater aquarium. If money is tight, don't set up a marine tank right now. If you start skipping needed equipment like protein skimmers or good quality live rock, you are just going to be cutting yourself short and making the hobby less enjoyable. Come back to it when the finances loosen up and set things up right.
