I am going with UGF as part of my tanks filtration system. However I want plants in the tanks. And lot's of them at that! I have read conflicting experiences - some say the roots will clog the UGF, others report very few issues with plant roots. I am wondering if bigger tanks might mean less issues? I'm going to risk it anyway but I was wondering if some plants are less 'rooty' than others? Anyone know of some good plant choices for planting on UFG - bearing in mind my tanks are only 24L?
