I run only Fostersmith phospur pads (cut to fit in canister filter) and purigen and have been since startup of this 14gl. I do have a chaeto/LR fuge. No PS. It stays algae free and the glass I wipe no more than once a weeks. Sand stays bleach white and clams are growing way too fast for such a small tank. I am probably going to have to get rid of them before too long. Water changes every 2 weeks. I wouldn't use bioballs myself. Use only LR.
