I'm thinking of using a kinda plant filter in my 135g when i get it running. i know its not going to be the only filter i just think it will look cool to have vines coming out of the top of the hood and watering plants w/ aquarium water. couple ?'s i was going to use PVC pipe w/ holes for draining (hoping for a rain type effect) being filled by the water out of a HOB. i'll probably just be using a few types of philodendron. i saw a type of hydroponic media called rockwool and was wondering if it is safe for aquariums and if it effects water condition. any ideas or tips would be great and i'll try to draw up some plans to post soon. oh and also any idea how to suspend this?
