dang won’t be able to do this then, already get yelled at for just the sound of my trident testing….I use the Neptune AFS on one tank and the eheim on another tank when I go on vacation. If you have an apex and want to make everything programmable with it then the AFS is okay. For the money the eheim works great.
Also, if you go with the AFS be aware that when it runs it makes an awful sound.
