The issues have been relatively minor thus far. I need to find some silicone aquarium sealant because my improvised seal obviously isn't doing the job.

Thanks for the compliments. Your 120 looks great!
 
I've had bad luck with some stem plants except for the anacharis, which I thinned out a few weeks ago because it was starting to look shabby. I've had moneywort and ludwigia repens.

Any suggestions for 1.8wpg?
 
Re-sealed the DIY CO2 with some aquarium silicone and everything is working great now. I'll be interested in seeing how my plants progress.
