i was having a slight problem with what i thought was brown algaea forming on the walls of my tank and on the ground and some of hte lr....everyone informed me that these were dead phytopplankton or something like that which was also the stuff floating in my water...but today i came on after having my light on for about two extra hours because i was out and now there is a slight green build up which does no wipe off as easy as the brown stuff....it kind of reminds me of sap almost...what is this?
