The Aquarium Buflding 



IT IS OFTEN assumed that a greenhouse might 

 constitute an ideal aquarium building. The author is 

 not in agreement with this view. An aquarium build- 

 ing does not require nearly as much Hght as is af- 

 forded by a greenhouse. In fact, the excess Hght may 

 constitute a problem. Especially where glass aquaria 

 are used, excess hght encourages algal growth and 

 makes it difficult to keep tanks reasonably clean. Al- 

 though large concrete or metal tanks can tolerate 

 considerable Hght without developing algal problems, 

 for general use, the light problem in a greenhouse 

 makes it undesirable as an aquarium building. In ad- 

 dition, a greenhouse has a very high heat loss and is 

 usually more expensive to construct than a more con- 

 ventional-type building. 



The author recommends a building of the following
