I am still trying to get my head around how 'successful low tech tanks' differ from, say a community or even a single species tank? I mean 'successful' as in growing healthy plants. So we have a soil substrate, a fertiliser regime, one wpg, & recently it seems 10 x flow & even weekly water changes! In fact I have also read high lighting works too & a trickle filter helps plus tank shape with a large surface area will help.... Golly it is getting to be quite technical ...! So my question is... a shallow tank with square footprint, soil substrate, trickle filter, 10 x flow, 20 - 50% weekly water change, 10% EI & 1-2 wpg will be a good low tech design?
