I have a 90 gallon severum and Geophagus tank and the Geo is really disturbing the old substrate that has been in the tank for about 3 years now and it is time to change it. I have used laterite and gravel but over time the laterite has crushed and now the Geo is sifting up what used to granuled to sand and creating a heck of a mess. I also have lots of plants that I have enjoyed keeping with these guys. I want to use eco complete for the bottom 1/3 of the tank and wanting to use Tahitian moon sand on top . Does anyone know how this would affect the plants? Would it be ok or would I be killing them. Any suggestions would be great!!!
