| 88. In the same area, what is P. striatus"? Small matters, these and a handful more, but in the life of a nit-picking editor-type, the real prey of the hunt. Oh, and worth listing to clean up for future editions. A Guide to Angelfishes & Butterflyfishes, despite my differences of opinions in aquarium survivability, has taken its soon-to-be-well-worn place on my reference shelves next to the two-volume MERGUS/Aquarium Systems and Wiley efforts in the seventies by Steene and Allen. The photos are exquisite, physical production a joy, the scientific information accurate, and listing of species and their classification up-to-date. Take a look at this bo More |
My principal "problem" with A Guide to Angelfishes & Butterflyfishes lies here. Maybe the authors derive their opinions as to aquarium suitability on the basis of stomach contents studies (zoo-plankton eaters good, coral polyp eaters bad), maybe their experience and second hand information (none are aquarists) is different coming frMore |
To use flow rate and head pressure to help you select a water pump, you first need to know: 1) how much water you need to move through your filter system (volume of your aquarium and filters combined), 2) how many times per hour you need to turn over the aquarium volume (flow rate - typically three to five times per hour), and 3) how much resistance (head) the pump will encounter as it moves water from point A to point B. The first two are easy. Calculating the resistance a pump will encounter as it does its job is a science. If you want to get precise, we recommend you purchase "Aquatic Systems Engineering" by Dr. Pa More |
New to the hobby
Hi, I'm trying to absorb as much information on Reefs, sw fish ect. So far we have a 55g tank with 2 Emperor 400 filters (minus the bio wheels), 12lb of LR (going to get more very soon), 40lb of crushed coral and two tiny black and white damsals. We have a r.
