Zacro First Impressions

That was cool.

I confirm it with my cooking digital probe thermometer. The suction cups are large, high quality and seem to stick great. I went ahead and went with the the larger 300W for my 45 gallon. We received the chiller promptly and put it into use. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. I use this little heater for my 10 gallon quarantine tank. I will definitely be buying another one for my other tanks at bigger one.

Zacro Final Thoughts

5 gallon tank.

And I get to keep the first one I bought! Pressing and holding the button for 5 seconds changes it from F to C readouts. Awesome chiller, perfect for Hydroponics. I like to keep it at 72 and from my thermometer it is reading at exactly 72. I will definitely be buying another one for my other tanks at bigger one. I am very happy with this purchase. No biggie, but annoying nonetheless.
