Review on YDDHHB Submersible Fountain Aquarium Hydroponics by Yalena Torres

Significantly overpriced at 80 gallons per hour. You're going to have a hard time getting 20 gallons down the hill. It wouldn't even rise 2.5 feet for my garden fountain. No water came out of the spout. I checked twice to make sure the hole on it had been adjusted the wrong way, but it was wide open. So I put it in my tank to induce directional flow in my 34 gallon tank. nothing, you can't even feel or see any flow. My smallest catfish, an inch long, swam straight at them out of curiosity, but to no avail. She threw it in the trash can. Not worth sending back either.
