Hey. I was looking for some help on what dosing regime I should be doing. Tank - Juwel Rio 125 (125litres, 33USgallon) Lighting - 4x18W CO2 - 2kg fire extinguisher, Rhinox 2000 at 1 bubble per second Substrate - ADA Aqua soil Malaya Ferts - TPN+ Water changes - 30% weekly. Regarding plants, I'm stocking up with plants as soon as they are availabe. Atm I've got blyxa japonica (thanks James), glosso (thanks Dan) and I've got some rotala sp. green on the way (thanks Simon). Aventually, pretty much all of the substrate will be covered with plants. So, just wanting to know how much of the TPN+ i should dose, and how often? Thanks.
