I need to upgrade my powerheads 30. How would this work in my 15 gal nano? I need stronger flow for my suncorals/dendros. Does it create movement from the front as well as the sides? Sorry for all the questions
Koralia pending KathyC. This is new backup unit that I never use, selling because I am ugrading my tank. I used Koralia one on my 20 gallon which is about 24 inch in length. Very strong flow that sending current all around. Bit too strong for some softy/LPS in small tank.
