Review on 🐠 Hygger Quiet Magnetic Wave Maker for Aquarium - 1600GPH & 2600GPH Powerhead with Digital LED Display Controller - Submersible Water Circulation Pump for Fish Tank 3-55 Gallon by Susan King

I bought it in May 2020 with a new AIO tank, it was really stupid to get used to it because on their (hygger) Program is based on 4 digits representing a wave, you need the power of that wave and the frequency of that burst of the wave, it was really silly at the beginning but you learned to deal with it. Now it doesn't work, it shows error 7. I don't see any kind of reset on it so I'll contact the company. I learned my lesson by cutting corners to save a buck, most powerheads average 100, spend 75, and where am I with nothing. BUY QUALITY PRODUCTS for your aquarium if it is salt and you want it to last for several years.
