Tray not drained completely after flood cycle
My tray does not drain completely after flood cycles because the plug is higher than the tray, like so
This site says that leaving water in the tray after floods will create problems with pythium. see here: http://www.living-learning.com/faq/homebflo.htm
i am thinking of adding gravel up to the top of the plug and having a mesh filter on the hole to prevent gravel from falling
how did you guys work around this problem ?
