Types of Aquariums

Aquariums come in all shapes and sizes imaginable and we treat them all with the same love and devotion. From the fancy shrimp sitting in half a gallon tank on your office desk to your dream aquarium of several thousand gallons, freshwater aquariums can be a little tricky with water chemistry.

We recommend selecting freshwater fish from one region or from very similar regions due to the importance of pH. African cichlids, for example, come from an alkaline high pH environment whereas tetras, angels, and oscars come from the acidic low pH environment of the Amazon. Selecting fish from similar environments will guarantee maximum coloration and proper intake of nutrients resulting in happy healthy fish. Before making a permanent selection of marine systems, there are several variables that must be considered. Sea horses should not be housed with anything but other sea horses and their cousins like pipe fish. Being slow eaters, other fishes easily out compete them for food. Seahorses and pipe fish are also prone to being picked on simply because they rely heavily on camouflage for aggression prevention in nature.

Sharks and rays are not quite the big, aggressive animals that comes to mind. They are quite intriguing and rely heavily on sense of smell and electrical current. But due to poor eyesight, they get targeted easily, eventually succumbing to the stress of constant fin and tail nipping. Tank mates like groupers and lionfish make excellent companions.

Fish with tendencies to swallow large prey are much better choices than tangs, angels, and butterflies that spend all day nibbling algae off the rocks.

Reef systems are for the hands-on hobbyists only. You need to know your system and how it works to have success. Spectators that don’t like to get their hands wet should steer clear.

Corals can be aggressive just like fish. Not all corals will get along. They also come from a variety of environments. Elegance corals, flowerpots, and long tentacle anemones, for example, come from shallow warm lagoons filled with sea grass. These areas are typically saturated with nutrients to support the growth of sea grass, a striking difference from the environment of SPS corals found in the offshore reefs where the water is turbulent from the open ocean, which is completely void of nutrients and has considerably cooler temperature than the lagoons of the shallows.

The space in between the offshore reefs and lagoons are home to a wide variety of hardy LPS corals, soft corals, polyps, and corallimorphs. Here, nutrients are diluted, water is lukewarm, and the tide and turbulence keep everything moving but lacks the slight chill of the open ocean currents.

The biggest mistakes made with reef systems is over stocking and over feeding, as corals do poorly in high nutrient environments. Fish should be kept to a minimum.

There will always be exceptions to the rules. Some people keep African Cichlids and South American Cichlids together, while some have a bunch of fish in reef tanks. Some people keep tangs and angels with sharks and rays. People will always have different choices. When It comes to aquarium maintenance in Orange County, we will always do our best to help you take well informed and educated decisions concerning your choice of livestock.

Water Quality

  • Salinity/specific gravity– Natural sea water has a salinity of about 34 and specific gravity of 1.025, which can be measured using hydrometers.  Invertebrates are going to be the most sensitive to salinity changes, e.g. shrimp and starfish. Freshwater baths have been used as a preventative dip for new fish. Salt is sometimes used in ponds and freshwater aquariums as well.
  • Temperature– 76 F to 78 F is passed as the ideal range, as lower temperature water holds more oxygen. Temperatures also affect salinity/specific gravity reading. Corals have a tendency to bleach out when exposed to higher temperatures, while fish from faster moving streams tend to enjoy cooler water. Fish only tanks can be kept over 80 F to help suppress parasites. 
  • pH- (pondus Hydrogenii) or sometimes called the power of Hydrogen- Every living thing has an ideal pH range. Absorption of nutrients is directly affected by pH. Fish from the Amazon prefer a low acidic pH while fish from Africa typically come from a high alkaline pH environment. Lighting will also affect pH, as it naturally drops a little at night. 

Foods and Feeding

What type of fish you keep will determine what type of food you feed. There are 3 basic categories and a variety of specialty feeders. Carnivores, herbivores, and omnivores make up the majority. The more protein in the diet the more phosphate is produced. There is a significant difference between foods for freshwater fish and marine fish. Because it is so saturated with nutrients marine fish have a slime coat that keeps minerals out and lets fresh water through, as they need to consume all nutrients. Most freshwater fish are exactly the opposite. Their slime coat prevents water from entering but they can absorb many important nutrients straight from the water, as they don’t need to consume all nutrients.

The most common problem in the aquarium industry is over feeding. A fish’s stomach is usually only as big or smaller than the fish’s eye. So, don’t let food hit the substrate and use small amounts at a time. If any food is left over after feeding, it means you fed too much.


There are 3 main types of filtration; mechanical, chemical, and biological, when it comes to fish tank maintenance in Orange County.

  • Mechanical– Removal of solid particles. Our recommended method for mechanical filtration is a filter sock on a sump. Canister filters can be used on larger systems. Hang-on-back filters are only recommended for smaller freshwater aquariums. Protein skimmers are for saltwater only as they can filter out the finest particles that pass through standard mechanical filtration. There is some debate with skimmers filtering out important nutrients. Putting the skimmer on a timer to only skim for a period of time after scheduled feeding has been recommended. Make sure to remove, replace, or clean filter socks and other mechanical filtration media after 3 to 7 days or accumulated waste will start to dissolve. Dissolved waste will saturate many types of rocks, wood, and substrates. If a large water change is performed following extended periods of saturation it will likely cause dissolved waste to be released and could potentially cause a system crash.
  • Chemical– Removal of tannin and impurities. Freshwater aquariums sometimes contain drift wood and branches that leach tannin into the water and turn it brown or yellow. Soaking the wood prior to use will prevent some of this but it will continue to leach over time. Good old standard activated carbon should take care of it. There are a good variety of chemical medias available that can be used to remove harmful medications from the water. It is not recommended to use chemical filtration continuously, as carbon dust has been linked to HLLE (Head and Lateral Line Erosion).
  • Biological: ‘The Cycle’- Two types of bacteria are responsible for a successful cycle. The first type to develop will convert ammonia into nitrite. The second type converts nitrite into nitrate. Nitrate is why we do water changes. Some products and equipment can be used to help remove nitrate. Fish excrete ammonia in the form of respiration, defecation, and urination. Ammonia can also come from uneaten food and dead/decaying plant or animal matter. If you get an ammonia spike it will look like milky, cloudy water. The fish might be gasping for air at the surface, as ammonia is toxic and removes oxygen from the water. This will only happen in the ‘cycle’ stage of set up or if the tank starts crashing. 


Advances in the lighting field are constantly being made. Fluorescent lighting is what we were limited to in the beginning. Now we have t-5, halogen, and LED. All have pros and cons.

  • T-5 is affordable and reliable but can’t quite get light to the bottom of a deep tank as well as LED or halogens.
  • LED are only as good as the lenses. Many people feel LED is the future for aquariums. They can be expensive to purchase but cheap to run and never need to be replaced.
  • Halogens are expensive to purchase and expensive to run. They are still leading the way for best lighting for coral, especially SPS coral.

You don’t always need to have your light on. Fish only tanks that do not have photosynthetic tank mates can survive without light as long as they are exposed to ambient room lighting. Fish need a consistent photo period to be happy and healthy. Lights that go on and off at the same time every day. Less light will keep algae growth minimized.

Parasites & Diseases 

Parasites, diseases, viruses, and fungus are the enemy. Some parasites like Ich are always present in the aquarium. There are 3 stages of the Ich life cycle; cyst stage, free swimming, and the final stage when it has attached to the host. Ich will be triggered to emerge from cyst stage when fish lose the protective slime coat under stressful conditions.

A happy healthy fish has a thick coat of slime to prevent parasites and such from hosting. Quarantine is recommended for a minimum of 3 to 4 weeks. After 3 weeks’ time, you can be assured nothing unwanted came home with your new fish. Medication isn’t always necessary for quarantine, but it is recommended.

Cleaning and Maintenance

The least stressful method for fish tank cleaning service in Orange County is frequent small water changes rather than a big flush once a month. A weekly water change of 10% would keep your nitrates under 20 ppm in a perfect world if the system was not over stocked and over fed. Any water change over 50% could be detrimental to the beneficial bacteria and may cause an ammonia spike. Some fish, usually aggressive predators can handle a big flush and extreme changes in the environment. Cleaning mechanical filtration frequently will help reduce waste accumulation. Most aquariums do well with a 25% to 40% water change every other week.
