I bought a 2k iceCap for my nano tank as I have a 4k! However: this pump is pushing enormous amount of water out, eventhough; I am running it in 1 percent I had to change it in setting to icecap 1000 to slow the pump down. As it did cause my tank to go upside down more less. I am running it with hudros controller and it is on 1% right now hoping to know how to fix this issue. It's pushing more water then my 4k running at higher percent.
