I was figuring out my new tanks plumbing and I figured a 1" felxtube would be easiest and the best way to plumb into my sock holdeer/sump..Any negatives or would anybody suggest not using a flextube for any reason?And of course I will hard plumb my return ...Thanks Sal
if use flex tube, avoid clear type to avoid algea growth inside the tube. other wise i dont see any disadvantage other cost. i've been using eheim for their quality tubing.
