these fans are a must have! it definitely helps cool down your tank without using a chiller. it’s easy to attach to either your tank or to the sump and you can adjust the direction of it.
it really works! i plugged it in and within the afternoon, it dropped my temperature 1 degree. so when my lights come on later, it should help stop the temperature increase dramatically. love it!
one thing is that mine is the 4 fan version not this 2 fan version.
