1. TRUE or FALSE. Pond-free features, by definition, are recirculating water features with a closed reservoir and a natural look and feel.                    
2. Pond-free advantages over ponds include all of the following except...
3. Water Matrix Blocks have become popular because...
4. TRUE or FALSE. A gravel-filled reservoir holds 1/3 the water as the same size Water Matrix reservoir
5.  TRUE or FALSE. The gravel in the reservoir will occupy about 2/3 of the space, leaving only 1/3 available for water, regardless of the size of the gravel.
6. Atlantic Water Garden's Eco-Blox are capable of supporting                   tons of distributed load.
7. All of the following statements are true except:
8. TRUE or FALSE. The deeper you make the reservoir, regardless of volume, the more water you’ll have over the top of the pump to guard against overheating. 
9. TRUE or FALSE. Check valves are useless for Pond-free water features because there are no bacteria to keep submerged. 
10. TRUE or FALSE. A well-designed waterfall spillway box should diffuse the jet of water coming out of the hose, support the weight of heavy stones and secure the liner to ensure against leaks. 
11. For Pond-free features with a stream, the easy way to figure the volume a Water Matrix reservoir should hold is to take the dimensions of the stream and multiply:
12. Refering to a water feature with a stream 8’ long and an average of 2 feet in width, needing only about 3” of water depth to start recirculating when turned on... The Total Dynamic Volume of the stream, the water in motion when the pump is running, is:
13. Refering to a water feature with a stream 8’ long and an average of 2 feet in width, needing only about 3” of water depth to start recirculating when turned on... The total volume of the reservoir should be around:
14. Refering to a water feature with a stream 8’ long and an average of 2 feet in width, needing only about 3” of water depth to start recirculating when turned on... To have enough water in the reservoir you’ll need room for at least:
15. Refering to a water feature with a stream 8’ long and an average of 2 feet in width, needing only about 3” of water depth to start recirculating when turned on... If you would rather not use EcoBlox, and just backfill gravel around the pump vault, you’ll need:
16. Setting the bottom of the Pump Vault 4-6” lower than the Water Matrix Blocks serves two important functions:
17. TRUE or FALSE. Setting the top of the reservoir well below grade can add height to your waterfalls 
18. TRUE or FALSE. Installing and activating a Pump Protector without letting the feature run for a while can mask a leak.
19. TRUE or FALSE. Pond-free reservoirs and Rainwater Harvesting are a great combination, to top off water features whenever there’s measurable rainfall, and to circulate and aerate collected water. 
20. TRUE or FALSE. Grade the soil surrounding the reservoir to capture any rainwater that falls.             
21. Ponds that have both fish and plants:
22.  Koi can be costly to maintain because:
23. TRUE or FALSE. The oldest recorded nishikigoi was already 30 years old during the American Revolutionary War and lived until 1977. 
24. Rolls of EPDM Fish-Safe Pond Liner can be purchased off the shelf in sizes up to:
25. A general rule of thumb for overflowing vases or basalt columns is to provide                      .
26. The three most common components of the typical pond circulatory system are:
27. TRUE or FALSE. Water leaving a properly functioning biological filter is screened of fine particles, full of nitrates and well-aerated by the stream or falls before returning to the pond. 
28.  The best reason listed below to consider a Skimmer for your pond is:
29. A safe and responsible pond always has                               for access and safety.
30. The profile of the pond will affect:
31. All of the below are advantages of the Simple Step, Rock-and-Gravel design EXCEPT:
32. An initial 18”-24” deep step down into the pond onto a flat shelf is advantageous because:
33. The larger and deeper the pond is:
34. Dialing 811 anywhere in the country is a critical step before you dig because:
35. The pond’s pump should be located as far from the waterfall as possible for:
36. What determines the type of pump required for a pond?
37. One good way to figure the size of the liner for the pond is to add the length of the pond to twice the depth plus 2 feet, and round up to the nearest multiple of 5, then do the same for the width. How do you measure the length and width of the pond?
38. Figuring the liner for the stream is a little different because you measure length and width, add twice the height then add 5 and round up to the nearest multiple of 5’. Why?
39. TRUE or FALSE. Bogs are difficult to install in or around Koi ponds.
40. TRUE or FALSE. It’s always a good idea to leave a fold of extra liner below the attachment area of both filter and skimmer, to ensure that the weight of the water doesn’t pull the liner off the equipment, and so future settling of soil or rocks won’t pull on the liner and cause a leak.           
41. Decorative Water Features are...
42. Decorative water features are                               features that recirculate water from a closed basin.
43. All of the following are used to create Decorative Water Features except?
44. Decorative Water Features are extremely versatile because..
45. Decorative Water Features can be very economical to operate because...
46. A genreal rule of thumb for overflowing vases or basalt columns is to provide                          .
47. The Eco-Rise/ Eco-Blox system is a way to install                                 Decorative Features directly over the water reservoir.
48. One great technique to make a Decorative Water Feature appear as if it's been part of the landscape for years is to...
49. Decorative Water features can be adapted to any budget because
