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.

Water changer I’ve tried the cleaning kit and the 49 foot water changer and I really enjoy hygger quality and thoughtful construction. The faucet attachment comes with all of the adapters and the hose I a great length without being too heavy. The attachments for the siphon are awesome as they increase the suction when attached. The shut off valves are a super bonus. Love this waterchanger!

HG902 heater died after 2 months use HG902 heater died after 2 months use. No support from company. Intially responded to first email for assistance, then no response to follow up emails. Heater cost over $100. Would expect better quality and customer service when paying that amount.

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.

Waste of money… Got a hygger gravel aquarium cleaner first one made it thru ONE cleaning and was spraying water all over the place near and at the spigot end contacted the company the sent me a replacement against my better judgment.... would have preferred a refund since it barely made it thru one use. The replacement didn't even last one use. Do not waste ur money on this product... it truly is a piece of junk.
