Hobbyist Profile: Charlie Drew and the Elusive Red Crypt
Author: Richard Sexton
Some plant species are rarely found in the hobby, and then there are some, like the giant red crypt, that hardly exist in the hobby at all. A hobbyist discusses his decades-long search to uncover the identity of the giant red crypt found almost exclusively in a single hobbyist’s home in Canada.
In the November issue Dave Boruchowitz explores the math of water changes but please allow me me to clarify Dave's math a little to put the numbers in perspective. Additionally some comments about "pollutants" and fertilizer levels with this method are given.
