I have a 40 breeder and I don’t have a hob filter or a sump that I can put the ato in. I will be running wavemakers also. I was thinking of using the smart ato micro because I have had great experience with it and it has a good price. However, being that this is 40 gallons, would that ato even work? And should it be fine with the waves? If you have a better suggestion please let me know. Thanks
