I've set up my low tech tank, 2-3cm of Westland Aquatic Soil then some plastic mesh with about 3cm of large grain sand on top. I've planted a cryptocoryne wendtii, echinodorus red diamond, some bacopa australis, hydrocotyle sp Japan, a fern plant that I lost the card for (tropica plants) and I'm waiting on java moss being delivered. I have 24 watts of t5 lighting with a reflector, the tank was only set up yesterday. A few questions though, I have a HOB filter so there's no flow in the tank, what could I use to increase flow in a 15" cube? When do I start adding my Seachem Flourish ferts? How long will the tank take to stabilise with the ammonia leaching from the substrate? Should I be doing water changes? Alot of questions I know, I just want to get this right from the start!
