MST 100: Marine Aquarium Systems

STUDY GUIDE FOR FINAL EXAM – Exam is Fri, Dec. 17, 1:00 p.m.

Bring one Scanton (1-100) and at least one pencil + eraser for the exam. 

The exam will cover: Filter Structures & Types, Protein Skimmers, Sterilization & Lighting, Acclimation & Species Compatibility, Special Marine Aquarium Systems, Feeding & Nutrition, Disease diagnosis, treatment and prevention, and Aquarium Math.

Aquariums are a dynamic process and you should be able to apply knowledge gained from the entire coursework. Emphasis will, of course, be placed on the topics listed above as well as the project goals.You should have a good understanding of the water chemistry, ecosystem and the devices used in your aquarium systems since this was  

This is a study guide that specifically covers the  last 1/2 of lecture topics (since the last exam) and should be used along with your class Manual, your lecture notes, lab exercises, quizzes, worksheets, etc.,  when preparing for the examination.

 

Filter Structures and Types:

 

Recognize, Identify and know which types (i.e. slow or rapid) of filtering is accomplished:

Undergravel filter                    Submersible             Canister filter

Foam block or Sponge Filter                External Canister filter

Fluidized bed Protein Skimmers

     What are “denitrifying” filters?

What are the problems associated with in using them?

What are problems associated with algae scrubbers?

What condition or environment do biological filters work best?

 

Protein Skimmers:

 

What are they (i.e other common names)?

What type of filtering process do they use? 

What serves as the filtering media?

What is a venturi?

What are the most important factors that affect their effieciency? 

     What types of skimmer designs are there and which work best?

What types of conditions do skimmers work best in (freshwatervs saltwater)?

     What are the advantages and disadvantages of using one?

 

Sterilization:

 

What are the types of sterilizing methods used and how does each accomplish this?

     What are the hazards and precautions with each in their use?                 

      

Why is the air dyer recommended?

How do you install air dryer with respect to the ozone unit, air pump and protein skimmer?

What factors affect the in the use of UV sterilizers efficiency?

 

Lighting:

 

What does Kelvin degrees represent and what range do we try to provide in the tank? 

Why is spectral quality important to some photosynthetic tank systems?

What region(s) of light spectrum do marine photosynthetic organisms require?

What is the most important consideration when selecting lights? 

How do you regulate photoperiod? Why is it necessary to regulate photoperiod?

Why do you need to replace bulbs, even if they still provide light? How often?

What are they and something about each type:

     Actinic                           VHO                              Full Spectrum

Metal Halide                    Compact fluorescent           10,000 K

Super lighting and custom lighting systems: 

        Height of the hood? 

        How would you set the timers for actinics, low white-lights and halides and fans?

 

Acclimation & Selection of organisms

 

What factors should you consider before selecting organisms?

     Examples of negative interactions

     Examples of neutral and positive

What can you do to eliminate potential “problems” when adding new organisms or fish?

What is the acceptable or standard “acclimation” procedure?

What is not advisable when acclimating?

What’s the big deal about rapid pH increase and high ammonia levels in the transport bag of water?

What is the biggest concern when transporting organisms? 

 

Special Aquarium Systems

 

What is “live rock”?

What are “reef systems”?

Describe the basic design features of the following “classic” marine aquarium systems

              Be able to explain the basic principles that allow the system to operate effectively.

                       (I.e. Protein skimmers, Calcium Reactors, Miracle Mud, Kalkwasser,  thick gravelbed, void, space, etc,…)

                                Berlin System                                     Plenum method

                                Natural Ecosystems (Leng Sy’s system)      Trickle Filter or trays

                                Traditional UG (Undergravel) system

Miscellaneous Hybridized Systems and other ideas (what is the purpose):

Refugium                Mangroves              Sea Grass Beds

How do you set up Mangroves (range of water, circulation, temp and light needs, how can you “plant” them?)What are Kreisel tanks?

How or what would you use them for?

 

Feeding: Food, Feeding Modes and Nutrition

 

What are the easiest “feeding modes”? Which ones are more difficult?

              Omnivore                        Active predator

Herbivores                       Passive predator

              Grazers                           Suspension and Filter feeding

Recognize the common fish & invertebrates used as examples for each of the above 

                                          

Why is nutrition such a big deal?
