it's a crappy picture, but you can see what's become of the bacopa and crypts in my tank... for some reason the plants on the left are less inclined to explode with new growth, i think it's because of the flow from the filter.
this is a low tech tank, mind you. it had DIY CO2 but it kind-of stopped working... it's got T8 stock lighting, osmocote root tabs and a mesh bag of osmocote stuffed in the filter for fertilizer.
recently the bacopa grew so high that i had to trim about six inches off three of the stalks(? is that the correct term i don't know haha)... i'm really happy with them, and honestly surprised they grew this well.
