Review on 🐠 AQQA Submersible Aquarium Heater: 100W/200W/300W/500W/800W, External Temperature Controller, LED Temperature Display, Suitable for Marine Saltwater and Freshwater Tanks by Agustin Bush

This product arrived at the very last moment! I noticed my old Hygger heater was starting to fail and my wife ordered this one. I was concerned about the quality but I am totally impressed with this heater! It makes my hygger look like I got it from a dollar store and includes a lot of handy features like a hook, PVC lid, auto shut off, digital controller that sits outside, temperature memory, etc. Honestly. Just wow! I am very happy with this purchase. I have it in a saltwater tank sump that has a 1100 GPH flow and requires a higher temperature threshold to keep up with the fast flow. The quick heat feature is impressive as it quickly got my tank up from 71 after my old heater crashed and the temp later went up to 73.10/10 minutes. My down jacket is very, very happy (and curious) with the upgrade.
