Don't buy it not quiet I'm making phytoplankton and this pump isn't quiet, it changes speed on its own somehow... If you turn it between the difference in noise, there's a low hum and a higher hum if you put dial between the two settings "high hum low hum" if you will call it that it somehow goes from one to another I might have to tape it until I find a better air pump... Idk how they call these things quiet.

Fantastic Company. I've now bought two items made by Hygger: A smart heater A smart light Both products were extremely well packaged and had concise instructions. The build quality of both FAR surpassed my expectations (especially considering the very reasonable price). I'm especially impressed with the light as it's so adaptab!d in its functionality. I DID have a few questions regarding the light and customer services replied with answers within a day! Great products and great company!

I have been using Hygger for years I have been using Hygger products in my aquariums for years now. From mini aerators for shrimp tanks to heaters for my trophy winning Flowerhorn they have done great for me and never caused an issue. I recommend them to anyone looking for great products without having to pay inflated prices of competitors at big box stores.

Being new to keeping Marine fish Being new to keeping Marine fish, I did research on the cost of equipment, I realised how expensive it was going to be. The Hygger heating system caught my eye, so looked into it further. If there's one thing other than a filter system I wasn't prepared to compromise on, it was the aquarium heater, so I read the reviews and watch some YouTube vids. I chose the Hygger 200W LCD aquarium heater. It was 2 weeks before I placed it in the tank and began to cycle before adding livestock. Everything was ok, until I had a problem, too late to send back to Amazon, 30 days had lapsed, so I contacted Hygger, and after a couple of emails, they have sent out a replacement. I cannot thank them enough for their understanding of the problem and acting as efficiently as they have. Their customer service is outstanding. I will have no problem in returning for further purchases and advice if I need it. Great people to deal with.

Hygger LED Extendable Aquarium Light I just received my new Hygger aquarium light. It’s much brighter than what I had before. It has multiple LED color options & is extendable, but I think my favorite option is the turn-on & shut-off programmable feature. I can’t wait to order another for my 75-gallon tank!
