Review on EcoPlus Outlets Aquarium Fountain Hydroponics by Jasmine Hart

GREAT FLOW! Slightly noisier than the previous pump, but the flow (output) is absolutely AMAZING! It's about 40 dB, so there's a little hum. But put it on a towel and it will fall 1/2. The best thing is the great flow! I have measured two pumps in the lab and this one is $1 more and twice as loud but has three times the flow. It says it delivers 7.9 l/min, but I measured 5.17. Closer than the cheaper one (allegedly 4 L/min, actually 1.58)
