well here is my progress so far... i've planted some peace lilly in wire baskets hung from the rim... and down in the gravel i've planted aqua fern - trichomanes javanicum - remarkably still alive and apparently thriving. also i've attached to a lava rock a fern plant - microsorium pteropus. it looks good.





i've also attached a co2 thingy and added a cap full of plant grow iron enriched...

but my water has turned a sickly shade of green...

does anyone know the cause or possible remedy?

thanks,

tws
