quiet skimmer

Hello, I am looking to put a rubber mats under my pumps in an effort to minimize vibration and noise. Any suggestions on rubber padding I may use which will not hurt the fish or the corals? Thank you, TQ

So I filled up my system and got it cycling last week, and I was very pleased with how quiet everything was running. Standing next to the tank you could barely hear a thing-- 2 MP40QD and a Swine Jebao. Two days ago I flipped the switch on the Skimmer, Skimz Leopard SL183 with the new QPS pump...
