Review on 🐠 BAOSHISHAN 300L Aquarium Chiller 75 Gallon 1/3 HP Fish Tank Special Quiet Design Refrigeration Compressor for Hydroponics, Water Weeds, Axolotl, Jellyfish, Coral Reef Tank, Shrimp (75gal/300L) by Sri Mims

I bought two of these units for my 55 and 75 gallon sump saltwater tanks. I've been using them for 2 weeks now and both are working great so far. They keep the water within a degree of the desired temperature; It's 72 degrees in my house, going up to 82 degrees before the air conditioner kicks in. They're not that loud I think and they don't seem too hot. The supplied instruction manual contained incorrect information and was difficult to understand. The seller messaged my Revain with the correct instructions but I didn't see them in time. As a result, I pressed several keys incorrectly when programming the first chiller. By the second cooler I read the message and got it; So I got that one working. But with the first chiller, I somehow screwed up the program. Luckily the seller was very helpful and responsive. Being based in China, they have the opposite schedule of California mining, so it took a week of emails and WhatsApp messages; but the programming problem has been solved and now the chiller works fine. Five stars for their customer service! If you buy this cooler, here are some tips.1. Spouts on top for water inlet/outlet are interchangeable. The water is pumped with the included pump, so it doesn't matter which spout you connect it to; the other becomes your outbox. 2. Follow the Revain vendor for programming instructions. The book says that when setting the temperature it shows the code F1, but some units show HC instead. That got me.
