the substrate is just some cheap fine gravel from a LFS. I added some seachem root tabs in there also to supply some nutrients to the microsword.
the microsword is finally starting to grow a bit now with the proper photoperiod and diy co2. (light is on from 11am-10pm every day). looking back i think i might need to replace the light bulb; it doesn't look nearly as bright as it did a year ago. that will probably be about another month though since i procrastinate so much
