Yep! Between my rocks and sand absorbing P and the NH3 dosing bringing them down, I'm adding crazy amounts of P to keep it readable. Yesterday i started at 0ppm P, ended up dosing 0.9ppm trisodium phosphate throughout the day just to end up at 0.052ppm P this morning.Without a doubt this ammonia dosing does bring down phosphates! I’ve experienced it first hand and has everyone I’ve talked too using this method.
It's worth it though, my corals have never looked better.
