If you are feeding to run off it definitely eliminates the need. I've dropped it as well after learning how much my plants feed. I too run blumats and feed 1.0-1.2 ec now withiut dc without build up problems. Its a good insurance policy if you are feeding higher ec. Before i bought a truncheon and learned about low ec feeds i was following the directions on the bottles and when i finally took an ec reading on my res it was2.8ec and the run off was off the meter crazy high, so i believe the drip clean did save my ass as a noob...or maybe i just got lucky.
